The invitation of bids kick starts the process to procure a contractor for implementation of the ambitious project, which is part of government efforts to ease traffic congestion in the city’s major roads.
Tanroads stated in its bid invitation issued recently that the works consist of construction of 1 km six-lane elevated bridge along Sam Nujoma/Nelson Mandela Road with its approach up and down ramps.
According to Tanroads, the work also involves construction of a second elevated bridge for right-turn traffic from the two intersecting roads, comprising a platform served by eight up and down two-lane ramps, and bituminous standard approach and left turning roads, other ancillary works, diversion road and construction of up-country bus station.
“The Government has applied for a credit from the International Development Association towards the cost of the Dar es Salaam Urban Transport Improvement Project (DUTP) and intends to apply part of the funds to cover eligible payments under the works contract for the construction of Ubungo Interchange and Associated Works,” reads the Tanroads notice.
The notice further stated that the bids must be delivered to Tanroads headquarters in Dar es Salaam by 10.00 hrs local time on April 29, this year. Tanroads has already signed an agreement with Japan’s Sumitomo Mitsui Construction Company (SMCC), for the construction of a flyover at Tazara Junction along Mandela and Nyerere roads in the city.
The government said in Parliament last year that a total of 900m/- had been earmarked for compensation of property in order to pave the way for construction of the interchange. Dar es Salaam is on track to become Africa’s fastest-growing urban center according to United Nation.
According to the 2012 national census, the region had a population of 4,364,541, which was much higher than the pre-census projection of 3,270,255.
The African Development Bank says Dar es Salaam population could reach 21.4 million people by 2052 and is likely to achieve ‘mega city’ status—10 million residents or more—by the early 2030s.
