Unity Bridge, International road bridge at Ruvuma River border, Mozambique and Tanzania.

Unity Bridge crosses the Ruvuma River a few kilometres downstream of where the Lugenda joins it, linking Mtambaswala in Tanzania's Mtwara Region with Negomano in Mozambique's Cabo Delgado. The 720-metre road bridge is 13.5 metres wide, with 6.5 metres for vehicles and 1.5-metre shoulders for pedestrians on each side. Five kilometres of paved road were built on each bank.

The bridge concept emerged in 1975, shortly after Mozambique's independence, when leaders from both nations envisioned a physical link between their countries. Construction was completed in 2010, creating lasting infrastructure for cross-border movement and commerce.

The name Daraja la Umoja means "Bridge of Unity" in Swahili, recalling the 1975 accord between Julius Nyerere and Samora Machel. Near the Tanzanian end lies Mtambaswala, reached from Masasi via Nangomba; the Mozambican side faces Negomano in Mueda district, Cabo Delgado. The crossing carries the Mtwara Development Corridor traffic.

Crossing requires valid travel documents and passage through border control facilities that operate during specific hours. Visitors should expect longer waiting times during peak periods and should verify current entry requirements before traveling.

The structure forms part of the Mtwara Development Corridor, connecting remote regions while accounting for wildlife in the nearby Niassa Reserve. Its design demonstrates efforts to balance infrastructure development with conservation of wild populations.
