Nyahua-Chaya Road Upgrade

Project Description

Tanzania National Roads Agency (TANROADS) assigned ECG to prepare the feasibility study and update the detailed design of “Nyahua-Chaya Road” (85.4 km) in compliance with the International Bitumen Standards. The project is funded by the Kuwait Fund for Arab Economic Development (KFAED). 

The feasibility study shall determine the technical and economic feasibility of upgrading the existing gravel/earth, taking into account environmental and social aspects. The progression of the consultancy services from phase I to Phase II is subject to the results of the feasibility study. To ascertain the technical and economic feasibility of carrying out the proposed construction works for the road, ECG undertakes the update of detailed design and preparation of tender documents for International Competitive Bidding (ICB) as per the KFAED procedures.

Nyahua-Chaya road section forms an important link with the trunk road corridor (1,539 km) that traverses Tanzania from East to West. The road corridor starts at Dar es Salaam city, on the eastern part of Tanzania, passes through three regional headquarters and ends at Kigoma, on the Lake Tanganyika. Dar es Salaam is the leading commercial city and leading port of Tanzania, providing a gateway to the hinterland of Tanzania and several neighboring countries. The eastern end of the road corridor from Dar es Salaam–Dodoma (451 km) and the western end from Kigoma–Uvinza (112 km) are asphalt-paved while the intermediate part from Dodoma–Uvinza is still unpaved.
