Project General Description

The present intervention concerns the Dodoma City Outer Ring Road (110.2 Km) Construction Project. The project is a direct response to the need for improved logistics services to cope with the expected population boom and expansion of economic activities in the political capital of Dodoma. It comprises construction to bitumen standard of a new dual-carriage way Outer Ring Road of 110.2 km around Tanzania’s capital city, Dodoma.The Project provides vital infrastructure necessary for a more efficient development of the fast-growing Dodoma metropolitan region. Furthermore, it will also greatly boost regional integration for Tanzania and its neighbours given that the Project site lies at the crossroads of two major continental road corridors: (i) the Central Corridor which connects the Port City of Dar es Salaam to the Tanzanian interior and (ii) the Trans-African Highway 4 (TAH4). The Project will also contribute to easier and faster transportation of tourists and agricultural produce within and outside Dodoma City/Region. It has four main components, namely: (i) road construction and supervision; (ii) related development and empowerment of women; (iii) capacity building; and (iv) project management.

Project Objectives

The overall goal of the Project is to support Tanzania achieve more inclusive and sustainable economic growth through development of crucial transport infrastructure that significantly contributes to the country’s poverty reduction initiatives. The objectives of the Project are to provide efficient road transport access to Dodoma City, the rest of the Country as well as other countries in the EAC region.


The immediate beneficiaries of the project include the residents in Dodoma City, its suburbs and the surrounding rural areas with a population of approximately 2.4 million people (2018), of which about a third (0.8 million people) live in the City. This project will benefit road users, for local, regional and international transport, including farmers travelling to and through Dodoma city, through the reduction of traffic jams. The other beneficiaries are industrialists, traders and transporters whose operating and logistical costs will be significantly reduced due to construction of the main Outer Ring road and rehabilitation of the feeder roads.
