TANROADS Supervises the Building of Tanzania's Roads Worth Trillions. The Question Nobody Is Asking Is Why It Does Not Build Them.

Tanzania has spent decades and trillions of shillings building roads and transport infrastructure while simultaneously allowing the execution capability required to build that infrastructure to remain entirely in the hands of foreign contractors, creating a structural dependency whose cost is measured not in individual project budgets but in the accumulated institutional knowledge, technical workforce, and industrial capacity that never formed inside Tanzanian institutions. TANROADS manages 37,435 kilometres of roads and TARURA manages 144,429 kilometres, yet 69% of TARURA's network is earthen, budget disbursement reached only 12% of annual allocation in 2023/2024, and the Parliamentary Infrastructure Committee has proposed nearly tripling TARURA's annual budget to TZS 1.64 trillion to address the backlog. This article argues that Tanzania must make a deliberate institutional decision to build sovereign execution capacity within its road sector, identifies the structural cycle that has prevented that from happening, examines the domestic precedents that prove it is possible, and assesses what a national construction capability would require to develop at the pace that Tanzania's generational infrastructure era demands. Tanzania has been building infrastructure for decades at a pace and scale that few sub-Saharan African economies match, and the result is a road network whose physical expansion is visible, measurable, and genuinely significant for the country's economic connectivity. According to TANROADS' own institutional records published on its official website, the agency manages 37,435 kilometres of roads comprising 12,527 kilometres of trunk roads and 23,939 kilometres of regional roads under the Roads Act No. 13 of 2007, making it one of the largest road management mandates on the continent by network length. TARURA, established to manage district, feeder, and urban roads, oversees a further 144,429 kilometres of district road network, according to data reported by TARURA's Chief Executive Officer Engineer Victor Seff to the Office of Treasury Registrar in September 2024, a network that has grown by 32.6% over three years and which surpasses the CCM Election Manifesto 2020 to 2025 target of 143,881 kilometres. The government has tripled TARURA's budget from an average of TZS 275 billion over the prior four years to TZS 850 billion, according to Engineer Seff's public reporting, a genuine resource commitment that reflects the political seriousness of the infrastructure expansion agenda. The network statistics that both agencies publish contain a figure that the infrastructure expansion narrative rarely foregrounds and that any honest analysis of Tanzania's road sector requires to be stated precisely. According to Tanzania's Parliamentary Infrastructure Committee report presented by Committee Chairperson Dennis Londo in 2024, as reported by The Citizen, of TARURA's 144,429 kilometres of district roads, only 3,224 kilometres, equivalent to 2.23% of the total network, consist of tarmac roads. A further 41,107 kilometres, or 28.46%, are gravel roads. The remaining 100,098 kilometres, representing 69.31% of the entire TARURA network, are earthen roads whose passability deteriorates significantly during rainy seasons, periodically halting economic activity in the communities they are meant to serve. According to TARURA's Chief Executive Officer Engineer Victor Seff, speaking at the TARURA Workers' Council meeting in Morogoro in April 2024 as reported by IPP Media, more than 100,000 kilometres of the network are unpaved, and the agency has set a target of making 85% of roads passable in all seasons by 2025 to 2026. This is the infrastructure reality beneath the network expansion headline: Tanzania manages a road system whose overwhelming majority remains unimproved, and the budget required to change that is not being disbursed at the rate the improvement requires. The budget execution data compounds the structural argument further. According to the Parliamentary Infrastructure Committee report presented by Dennis Londo in 2024, in the 2023/2024 financial year TARURA was allocated TZS 818.02 billion for road infrastructure, of which TZS 710.31 billion were domestic funds and TZS 107.71 billion were foreign funds. Cash received as of 31 December 2023 was TZS 82.50 billion, equivalent to 12% of the annual allocation, enabling implementation of road construction and maintenance targets to reach only 38.84% of planned delivery. Londo's committee proposed raising TARURA's annual budget from TZS 710 billion to TZS 1.64 trillion for four consecutive years to address the infrastructure backlog, a proposal that reflects both the scale of the unmet need and the inadequacy of current resourcing relative to the network's condition. A system that allocates a budget and disburses 12% of it is not failing primarily because of contractor quality or procurement design. It is failing at the most basic level of public financial management, and no amount of local content policy or contractor development will fix a construction programme whose funds do not arrive in time to spend them. The institutional architecture that makes sovereignty impossible The most consequential institutional fact about Tanzania's road sector is not the network's condition or the budget disbursement failure, serious as both are. It is that the two agencies responsible for managing the country's road infrastructure were designed, and continue to operate, primarily as procurement and supervision institutions rather than as construction executors, meaning that no matter how much money flows through them, the execution capability that spending at this scale should generate never accumulates inside Tanzanian institutions. According to TANROADS, the agency's mission is to manage national roads network and airports development by planning, designing, construction, and road maintenance for socio-economic development through a competent workforce. The word construction appears in that mission statement, but TANROADS' organisational structure, which lists directorates for Business Support, Maintenance, Projects, Planning, Procurement and Contracts, Legal, and Internal Audit, describes an institution whose internal architecture is built for management and oversight rather than for direct execution. Notably, TANROADS' own stated underlying policies include support for local contractors development and labour based technology, a formal acknowledgement that the local capability gap exists and that the agency has a role in addressing it, without the institutional mechanism to do so systematically. The mission says construction. The structure says supervision. That gap between stated purpose and operational architecture is where Tanzania's sovereign execution capacity has failed to form. TARURA's institutional design reflects the same logic at the district road level. According to its mandate documentation, TARURA was established as a strategic intervention to execute non-policy government functions related to rural and urban roads network on behalf of the government, a framing that positions it as an implementing arm of government road policy rather than as a construction institution building its own technical capacity. The result is that both TANROADS and TARURA function as the interface between government budget and private contractor execution, issuing tenders, supervising delivery, processing variation claims, and managing completion documentation, while the engineers, equipment, supply chains, and project management systems that actually build Tanzania's roads belong to the contractors who hold the contracts. When those contracts close, the capability closes with them. The cycle that has prevented capability from forming The structural dynamic that sustains Tanzania's dependence on foreign construction execution is self-reinforcing in a way that procurement reform alone cannot break, because the cycle operates through the interaction of capability, scale, and capital in a sequence that each element of the current system perpetuates. Foreign contractors win major infrastructure contracts because they already possess the equipment fleets, the financing relationships, the technical workforce, and the project execution history that Tanzania's procurement framework requires bidders to demonstrate before they can qualify for large contracts. Tanzanian construction firms remain at small to medium scale because they rarely receive projects large enough to generate the revenue, the equipment investment, and the technical workforce development that would allow them to compete for larger projects in the next procurement cycle. The government then awards the next large contract to a foreign firm because local firms have not yet demonstrated the capacity to execute at the required scale, which is true, and which is true precisely because the previous contract was awarded on the same basis to a foreign firm, leaving Tanzanian firms in the same relative position they occupied before the project began. According to the Public Procurement Regulatory Authority's annual procurement statistics, local content requirements in Tanzania's infrastructure contracts have been applied with inconsistency across different contracting authorities, and the enforcement of those requirements at the subcontractor and supply chain level has been insufficient to generate the industrial learning and capacity accumulation that genuine local content policy is designed to produce. A foreign prime contractor who subcontracts a portion of earthworks to a Tanzanian firm while retaining the engineering design, the equipment provision, the project management, and the financial control within its own organisation is technically complying with local content requirements while ensuring that the strategic and highest-value elements of the project remain outside Tanzanian institutional control. According to the Tanzania National Business Council's reports on the construction sector, this pattern has been documented across multiple large infrastructure projects without producing the systematic policy response that its cumulative economic cost warrants. The financial consequence of this arrangement is not only about the margin on individual contracts. It is about the accumulated industrial value that leaves Tanzania with each completed project. Foreign contractors import equipment, engineers, and project management systems, depreciate that equipment across multiple African contracts, develop their engineers through exposure to diverse construction environments, and build the project track record that qualifies them for the next large tender. Tanzania funds all of that development through the contracts it awards and retains none of it when the contractor demobilises. The roads remain. The capability does not. What China built and why Tanzania should study it precisely The most instructive global precedent for what Tanzania needs to build is not the infrastructure that China has constructed across Africa, though that infrastructure is visible enough in Tanzania's own road and railway network, but the institutional architecture through which China transformed its domestic infrastructure execution into a globally competitive export industry. According to research published by the Johns Hopkins University School of Advanced International Studies China Africa Research Initiative, Chinese state-connected engineering corporations including China Road and Bridge Corporation, China Railway Construction Corporation, and China Communications Construction Company evolved from domestically focused state enterprises into globally operating infrastructure developers through a deliberate sequence of policy decisions that gave them the project scale, the financing support, and the technology access required to develop execution capability that eventually exceeded what private international competitors could match on cost and delivery speed. The policy sequence that produced those corporations, as documented in academic literature on Chinese industrial policy, combined large domestic infrastructure contracts that gave state enterprises the revenue and project experience to develop execution capability, preferential financing from state policy banks that allowed them to compete for contracts on terms that private firms could not replicate, and deliberate technology transfer requirements that ensured Chinese engineers and institutions accumulated the technical knowledge embedded in joint ventures with foreign firms rather than simply supervising foreign execution. The result, measured over approximately three decades of consistent policy application, is that Chinese firms now build roads in Tanzania, railways in Kenya, ports in Pakistan, and bridges across dozens of countries, having converted domestic infrastructure necessity into an exportable industrial capability whose geopolitical and commercial reach extends far beyond anything that Tanzania's current infrastructure spending is generating for Tanzanian institutions. Tanzania should study that sequence not to replicate it in its totality, which would require a different political economy and a different financial system than Tanzania currently has, but to extract the specific institutional logic that applies directly to its own situation: that infrastructure execution capability is not a natural byproduct of infrastructure spending, that it must be deliberately built through institutions that do the work rather than supervise the work, and that the distinction between a state that manages construction and a state that masters it is the distinction between a consumer of development and a producer of it. The domestic precedents that prove the model is achievable Tanzania does not need to look only to China for evidence that state institutions can develop genuine construction execution capability. Two domestic institutions demonstrate the model in sectors adjacent to road construction, and their existence is the most direct available evidence that the institutional transformation Tanzania's road sector requires is not theoretically impossible but practically precedented within the country's own government architecture. According to the Tanzania Buildings Agency's mandate documentation, TBA directly undertakes the design and construction of government buildings rather than solely supervising private contractors who do so, accumulating technical capacity, project management experience, and institutional memory through execution rather than through oversight. According to the National Housing Corporation's operational records, NHC similarly develops and constructs major real estate projects using its own institutional resources, giving it a depth of construction expertise that a pure supervisory body would not possess. The distinction between what TBA and NHC do and what TANROADS and TARURA do is the distinction between institutions that learn through building and institutions that learn through paperwork, and it is not a trivial distinction. An institution that executes a construction project absorbs technical knowledge about soil conditions, material performance, equipment behaviour, and workforce management that cannot be fully captured in a supervision report or a contract document. That knowledge accumulates across projects into an institutional capability that makes the next project cheaper, faster, and more technically sound than the previous one, compounding over time into the kind of execution expertise that Chinese construction corporations used to become globally competitive. An institution that supervises construction absorbs knowledge about contract management, procurement process, and regulatory compliance, which are genuinely important capabilities, but which do not generate the technical execution depth that sovereign infrastructure capability requires. What a Tanzanian construction capability would actually require The institutional transformation that Tanzania's road sector requires is not primarily a matter of reorganising TANROADS and TARURA's internal structures, though reorganisation would be part of it. It is a matter of making a deliberate policy decision that Tanzania will build sovereign execution capacity in its road sector, and then providing the resources, the mandate, and the protection from short-term competitive pressure that building that capacity requires. The Parliamentary Infrastructure Committee's proposal to raise TARURA's annual budget to TZS 1.64 trillion for four consecutive years, as reported by The Citizen, is the most immediate available lever, but it addresses the financing gap without addressing the execution gap. A TARURA with TZS 1.64 trillion and no internal construction capacity will disburse more money to foreign and domestic private contractors faster. It will not build the institutional execution capability that Tanzania's road sector has been lacking for two decades. A road construction division within TANROADS, beginning with the project categories where Tanzanian capability is already closest to competitive, covering feeder roads, district road maintenance, drainage systems, and emergency repairs, would generate the project revenue, equipment utilisation, and workforce development that allows execution capability to accumulate without immediately competing against the most capital-intensive foreign contractors on the largest projects. TARURA's network composition provides the natural starting point: with 100,098 kilometres of earthen roads requiring improvement, according to the Parliamentary Infrastructure Committee data, the maintenance and upgrading work available within the existing network is sufficient to sustain a meaningful domestic execution programme for years without requiring TANROADS or TARURA construction divisions to compete for major new project tenders. Technical academies attached to those construction divisions, modelled on the vocational training investment that the Government of Tanzania announced in May 2026 according to TANROADS' own news records, would address the workforce development dimension that equipment and capital alone cannot resolve. The objection that state construction entities are inherently less efficient than private contractors is addressed most directly by the evidence of the current system's own performance. Tanzania's existing model of foreign contractor dependence has produced its own documented inefficiencies across multiple Auditor General reports, in the form of contractor disputes, inflated variation claims, delayed project completion, repeated procurement cycles for the same project scope, and consultant dependency whose cumulative cost across the infrastructure programme is substantial. According to the Controller and Auditor General's 2024/25 audit report, which Uchumi360 documented in its April 2026 analysis of Tanzania's institutional governance, procurement irregularities and contract management failures in infrastructure projects represent a significant and recurring source of public resource loss. A 12% budget disbursement rate producing 38.84% of construction targets is not a standard of efficiency against which any proposed alternative should have to justify itself. The question is not whether the current model is efficient. It is whether Tanzania wants to bear the inefficiencies of a system that at least leaves capability inside its institutions or the inefficiencies of a system that does not. The generational infrastructure era Tanzania is entering The scale of infrastructure investment that Tanzania's development trajectory requires over the next three decades is not a temporary infrastructure boom whose end will allow the current model to be sustained without consequence. Dar es Salaam is moving toward megacity status according to United Nations Population Division projections. Secondary cities are expanding rapidly across all of Tanzania's 26 regions. Industrial corridors whose development Uchumi360 documented across its coverage of the SGR, Bagamoyo SEZ, and Mkuranga industrial corridor are multiplying. Logistics demand from the Central Corridor's growing regional trade flows, documented in Uchumi360's May 2026 analysis of the Tanzania-Rwanda bilateral agenda, is increasing at a pace the current road network cannot absorb without sustained investment in new construction and existing network improvement simultaneously. TARURA's own target of making 85% of its network passable in all seasons by 2025/2026, as stated by Engineer Seff at the Morogoro Workers' Council meeting, implies a construction and rehabilitation programme across more than 100,000 kilometres of unpaved road that no combination of private contractors, however well procured, will deliver without the sustained institutional execution capacity that currently does not exist inside TARURA. The industrial winners of Tanzania's generational construction era will be the institutions, public and private, that use the programme's scale to accumulate the equipment, the engineering talent, and the project execution history that make them capable of delivering more complex projects faster and at lower cost than their competitors. If those institutions are Tanzanian, the economic multiplier from the infrastructure programme, in employment, in technical capacity, in supply chain development, and in retained financial value, stays in Tanzania. If they are not, Tanzania will have built the roads and exported the development. According to TANROADS' own stated underlying policies, the agency formally recognises support for local contractors development as an institutional objective. That recognition has not yet produced the institutional mechanism required to deliver it. A country does not build economic sovereignty by outsourcing every strategic capability tied to its growth, and Tanzania has been in the infrastructure business since 2000, when TANROADS was established, long enough that the absence of a national construction champion is no longer an early-stage oversight. It is a policy choice, sustained by institutional inertia and the path dependency of a procurement system whose design makes it easier to award the next contract to a capable foreign firm than to build the domestic capability that would make that choice unnecessary. Reversing it requires a different kind of decision, one that accepts the short-term cost of developing domestic execution capacity in exchange for the long-term benefit of an institutional capability that compounds across decades rather than departing with each contractor's final invoice. FAQ What does TANROADS manage and how large is its network? According to TANROADS' official institutional records, the agency manages 37,435 kilometres of roads comprising 12,527 kilometres of trunk roads and 23,939 kilometres of regional roads under the Roads Act No. 13 of 2007. TANROADS was established on 1 July 2000 under the Executive Agencies Act No. 30 of 1997 and operates under the Ministry of Works. What is the condition of TARURA's road network? According to Tanzania's Parliamentary Infrastructure Committee report presented by Dennis Londo in 2024, of TARURA's 144,429 kilometres of district roads, only 3,224 kilometres, equivalent to 2.23%, are tarmac. A further 28.46% are gravel roads. The remaining 69.31%, more than 100,000 kilometres, are earthen roads that deteriorate significantly during rainy seasons. TARURA's CEO Engineer Victor Seff has set a target of making 85% of the network passable in all seasons by 2025/2026. Why did TARURA achieve only 38.84% of its construction targets in 2023/2024? According to the Parliamentary Infrastructure Committee report, TARURA received only TZS 82.50 billion in cash disbursements against an annual allocation of TZS 818.02 billion, equivalent to 12% of the budget, as of 31 December 2023. The failure to disburse budget at the planned rate directly constrained construction and maintenance delivery to 38.84% of targets. Parliament's Infrastructure Committee has proposed raising TARURA's annual budget to TZS 1.64 trillion for four consecutive years to address the accumulated backlog. Why does Tanzania continue to depend on foreign contractors for major infrastructure projects? Foreign contractors hold competitive advantages in equipment ownership, financing relationships, technical workforce depth, and project execution history that Tanzanian firms have not been able to match at large project scale, partly because the procurement system awards large contracts to established foreign firms rather than providing the project scale that would allow Tanzanian firms to develop equivalent capability. TANROADS' own policies formally acknowledge the need for local contractor development but the institutional mechanism to deliver it systematically has not been built. What domestic precedents exist for state construction execution in Tanzania? The Tanzania Buildings Agency directly undertakes design and construction of government buildings using its own institutional resources rather than solely supervising private contractors. The National Housing Corporation similarly develops and constructs major real estate projects. Both institutions demonstrate that state construction execution is achievable within Tanzania's institutional environment, providing a domestic precedent for the model that TANROADS and TARURA's road sector currently lacks. What would a Tanzanian national construction capability look like in practice? It would begin with dedicated construction divisions within TANROADS and TARURA, starting with project categories where Tanzanian capability is closest to competitive, including feeder roads, district road maintenance, drainage, and emergency repairs. Given that TARURA's network includes more than 100,000 kilometres of earthen roads requiring improvement, the maintenance and upgrading work available within the existing network is sufficient to sustain a meaningful domestic execution programme for years. Technical academies attached to those divisions would address the workforce development dimension. The goal is state capability operating alongside private competition, not state monopoly replacing it.
