Sector Results and Learning:
Transportation

This Transportation Sector Results and Learning page is a repository of evidence generated by all MCC-funded transportation interventions. To promote learning and inform future program design, this page captures monitoring data from key common indicators, showcases recent and relevant evaluations, includes all agency lessons from completed transportation evaluations to-date, and links to learning that has been aggregated across completed evaluations in the sector.

What Do We Invest In?

MCC has funded $3.1 billion in transportation interventions as of December 2022. These interventions fall into the following categories: transportation infrastructure; management, funding, operations and maintenance assistance; and transportation policy, regulatory, planning, financing and institutional development assistance.

Transport Infrastructure

These programs focus on the upgrading, improvement, rehabilitation and maintenance of transportation infrastructure such as roads, ports and airports to reduce transportation costs.

Management, Funding, Operations and Maintenance Assistance

These programs focus on building the capacity of local transportation public agencies/institutions to increase funding sources and cost-effectively manage, operate and maintain transportation systems.

Transport Policy, Regulatory, Planning, Financing and Institutional Development Assistance

These programs focus on building the capacity of local transportation public agencies/institutions to set policies and build planning and implementation capacities to keep transportation costs low.

What Have We Completed So Far?

MCC and its country partners develop and tailor Monitoring and Evaluation Plans for each program and country context. Within these country-specific plans, MCC uses common indicators to standardize measurement and reporting within certain sectors. See below for a subset of common indicators that summarize implementation achievements across all MCC transportation investments as of December 2022.

What Have We Achieved?

MCC commissions independent evaluations, conducted by third-party evaluators, for every project it funds. These evaluations hold MCC and country partners accountable for the achievement of intended results and also produce evidence and learning to inform future programming. They investigate the quality of project implementation, the achievement of the project objective and other targeted outcomes, and the cost-effectiveness of the project. The graphs below summarize the composition and status of MCC’s independent evaluations in the transportation sector as of November 2022. Read on to see highlights of published interim and final evaluations. Follow the evaluation links to see the status of all planned, ongoing, and completed evaluations in the sector and to access the reports, summaries, survey materials, and data sets.

Connecting northern El Salvador through road improvements

High quality roads reduced travel time, but road usage has not met projections

  • Evaluation Type:
  • Evaluation Status: Final

MCC’s $449.6 million El Salvador Compact (2007-2012) funded the $268 million Connectivity Project to build, improve, or rehabilitate 23 bridges and 223 kilometers of road. The project was based on the theory that improving road quality would lead to reduced travel costs and decreased travel time, leading to increased use of the road. Increased usage of the road would then enable communities to participate more fully in the national and regional economy.

Unlocking Market Access via Road in Senegal 

Reduced travel times have not yet led to reduced transport costs for users

  • Evaluation Type:
  • Evaluation Status: Final

MCC’s $540 million Senegal Compact (2010–2015) funded the $324 million Roads Rehabilitation Project. The Roads Rehabilitation Project improved 372 kilometers of strategic highways and river crossings in the north and south of the country. The project was based on the theory that improvements in road infrastructure would reduce travel times and vehicle operating costs for road users, improving access to markets and services, which would in turn support economic growth and improve outcomes for local people.

Improving Roads to Reduce Transportation Costs in Mongolia

Road upgrades reduced transport costs but preventative maintenance is unlikely

  • Evaluation Type:
  • Evaluation Status: Final

MCC’s $269 million Mongolia Compact (2008–2013) funded the $75 million North-South (N-S) Road Project to reduce transportation costs along a critical corridor between Russia and China by constructing a 176.4 km all-weather road section from Choir to Sainshand and by providing the Government of Mongolia with technical assistance and equipment for road maintenance. The project theorized that these outputs would decrease road roughness, travel times, and vehicle operating costs and increase traffic.

Upgrading Transport Networks in Tanzania

Paving roads increased trade and mobility, but not all were cost-effective

  • Evaluation Type:
  • Evaluation Status: Final

MCC’s $695 million Tanzania Compact (2008-2013) funded the $405 million Transport Sector Project, which upgraded trunk roads in mainland Tanzania, rural roads on Pemba Island, and the Mafia Island Airport runway. 190 km of roads were completed at compact close, with the remaining 278 km later completed by the Government of Tanzania. The project aimed to increase cash crop revenue in mainland Tanzania and Pemba, and increase tourist spending on Mafia Island by reducing transportation costs.

What Have We Learned from Our Results?

To link the evidence from the independent evaluations with MCC practice, project staff produce an MCC Learning document at the close of each interim and final evaluation to capture practical lessons for programming and evaluation. Use the filters below to find lessons relevant to your evidence needs.

  • Optimize value of road investment through better design and quality control during construction: Limited sections of the Samtskhe-Javakheti road have experienced premature pavement failure after rehabilitation during the Defects Notification Period.

    Optimize value of road investment through better design and quality control during construction: Limited sections of the Samtskhe-Javakheti road have experienced premature pavement failure after rehabilitation during the Defects Notification Period. The potential causes of such failure were traced to design issues and as well as to lapses in quality control during construction. Establishing and enforcing an MCC standard for design review, which incorporates a greater level of technical expertise, could help to identify possible design deficiencies early on in the project development phase. In addition to more rigorous oversight processes, it is important to strongly enforce quality assurance and control requirements, as well as consider alternative forms of engineering contracts and project delivery systems to improve the quality of contractor feasibility, design and supervision.

  • MCC should explore the use of relatively low-cost methods of monitoring key intermediate outcomes, such as continued regular traffic counts, to better inform the time-pattern and composition of road impacts.

    MCC should explore the use of relatively low-cost methods of monitoring key intermediate outcomes, such as continued regular traffic counts, to better inform the time-pattern and composition of road impacts. While few if any detectable welfare/income benefits accrued over the time period studied, longer-term impacts cannot yet be ruled out. MCC, along with other donors, have learned that the time pattern of rural road investment benefits can be slower than was projected in this study. Since these findings do not distinguish between small total benefits, or slow realization of benefits, the magnitude of the full eventual benefits remains uncertain. More frequent monitoring of key intermediate outcomes could inform the appropriate time to conduct a follow-up household survey where significant household impacts are expected.

  • Don’t force investments to fit into one stated objective and associated project/theory of change when they logically do not – separate into a different project.

    Don’t force investments to fit into one stated objective and associated project/theory of change when they logically do not – separate into a different project. The evaluation showed the N1 Highway Activity was very successful at reducing transportation costs. However, because the investment was proposed late and the compact planners wanted it to fit into the existing theory of change, the stated objective of the Transportation Project of which is was a part (“to reduce transportation costs for agricultural commerce”) did not make logical sense for the N1 Highway and it is not likely that it was achieved by the N1 Highway.

    There was an attempt to synchronize the logic of the full compact (agriculture + roads), but that did not materialize. It increases risk when the success of one investment relies on another, and this situation should be avoided. In the case of Ghana, the success of the roads investments was predicated on increased traffic resulting from the compact’s agriculture investments. The results of the agriculture investments were limited: the farmer training activities were not well targeted, and the irrigation investments induced limited shift to growing high-valued crops, and so it is not surprising that the evaluation found neither the Trunk Roads Activity nor the Feeder Roads Activity to be cost effective. Furthermore, some of the agriculture investments were spatially detached from the roads investments, making this theory of change even more unrealistic.

  • Disconnect between the Agriculture/Irrigation program logic and Roads program logic.

    Disconnect between the Agriculture/Irrigation program logic and Roads program logic. Although both projects were designed to complement each other, the evaluation findings failed to show direct connection between the two sets of activities, and as such questions on trade of agricultural products were not sufficiently addressed.

    MCC now combines evaluations of all inter-dependent activities to minimize gaps in findings between those activities.

  • It is critical to comprehensively address policy and institutional constraints in road maintenance as well as seek assurances from the partner countries that the necessary mechanisms to ensure sustainability of their existing roadway network are in place prior to MCC committing to a capital-intensive road investment project.

How Have We Aggregated Learning Across the Sector?

MCC has developed a Principles into Practice paper using evidence from completed independent evaluations in the transportation sector Principles into Practice: Lessons from MCC’s Investments in Roads. The Principles into Practice series offers a frank look at what it takes to make the principles MCC considers essential for development operational in the projects in which MCC invests. The learning captured in this paper informs MCC’s ongoing efforts to refine and strengthen its own model and development practice in the transportation sector. MCC hopes this paper will also allow others to benefit from, and build upon, MCC’s lessons.
