Tanzania Opens 49km Mbeya Bypass to Boost Regional Trade and Safety
Tanzania Completes 49km Mbeya Bypass, Improving Safety and Trade on the Tanzam Highway
For decades, the Tanzam Highway has been the key economic artery linking the Port of Dar es Salaam to landlocked Southern African markets. However, the stretch through Mbeya City—especially the steep and hazardous Mlima Nyoka—has long been a major bottleneck.
In 2026, Tanzania has addressed this challenge with the launch of a 48.9-kilometre bypass designed to streamline transit and enhance safety.
The new Mbeya-Songwe bypass diverts heavy transit traffic away from the city center, avoiding the dangerous inclines of Mlima Nyoka. For years, trucks navigating the old route suffered mechanical failures, fatal accidents, and cargo theft. The bypass, spearheaded by the Tanzania National Roads Agency (TANROADS), provides a flatter, safer, and more efficient path for regional trade.
Economic and Safety Benefits
The bypass brings multiple advantages:
Reduced Transit Time: Long-distance haulers no longer congest urban streets, cutting travel times between Dar es Salaam and the Tunduma border.
Enhanced Safety: Heavy trucks avoid steep urban descents, reducing accidents.
Secure Trade: Dedicated transit routes minimize delays and risks of cargo tampering.
The Mbeya Bypass is part of Tanzania’s wider 2026 infrastructure strategy to modernize the Tunduma-Nakonde corridor. Complementary measures include the One-Stop Border Post (OSBP) and an Electronic Cargo Tracking System, ensuring smooth border processing once trucks bypass Mbeya.
Additionally, the Tunduma-Igawa road is being expanded into a dual carriageway, accommodating the increased traffic from the new bypass and preventing new congestion downstream.
With the 49km Mbeya Bypass now operational, Tanzania has transformed its portion of the Great North Road. The project not only eases traffic but also reinforces the country’s role as the primary gateway for trade to Zambia, the Democratic Republic of Congo, and other Southern African markets, making the “Highway to the South” safer, faster, and fully fit for purpose in 2026 and beyond.
