According to Dar es Salaam Rapid Transit (DART) executive director Ronald Rwakatare, the 360 billion/- expansion will link the city centre with the Mbagala suburb.
The new trunk lane will run along Kilwa road and part of Kawawa road, for a total of 19.3 kilometres up to Mbagala Rangi Tatu, which is expected to reduce travel time by 15-20 minutes, from the current of 60-90 minutes.
The project tender will be announced early January and a winner chosen to begin the construction job soon afterwards, Rwakatare told The Guardian in an interview over the weekend.
The African Development Bank has already released $141 million for the project and the government will cover the remaining part.
According to the DART boss, the project costs will also cover compensation payments for people who will be affected, he said.
The BRT project has been described as one of its kind in East Africa, transforming mobility and accessibility for increased productivity in a city of over five million people.
Phase One of the project covered 16km from the city centre to the Kimara suburb, with dedicated trunk lanes for its special buses, five terminals, 27 stations, three connector stations, and two bus depots.
It was funded by the World Bank to the tune of $180 million, and initially featured 39 trunk buses with a carrying capacity of 160 passengers each and 101 feeder buses with 80-passenger capacities each.
The entire BRT project will cover a total of six phases which, upon completion in 2035, is expected to greatly reduce traffic congestion in the nation’s commercial capital.
The third phase is set to cover 33.6km from Nyerere Road to Gongolamboto, and the fourth phase will cover Ali Hassan Mwinyi Road to Tegeta (22.8km).
It is estimated that by 2030, Dar es Salaam will have at least 7.8 million inhabitants generating 10 million trips per day.
