Isaka is a small town and station on the Mwanza railway line of Tanzania which connects to the seaport of Dar es Salaam. In the 1980s a so-called dry port was established there to serve the landlocked countries of Burundi and Rwanda, since Isaka is on a highway, now paved, running 610 km from the Rwandan capital, Kigali. The dry port functions as a sub-port of Dar es Salaam. Road transport companies can collect containers coming from overseas at Isaka and clear customs there, and deliver containers going overseas to the same location.
Isaka also handles containers for the north-eastern Democratic Republic of the Congo.
In 2006, China offered funds to carry out feasibility studies to extend the Tanzanian Railway system to serve Burundi and Rwanda directly. There is an alternate plan to connect these landlocked countries to the Cape Gauge southern African railway network via DR Congo, but the DR Congo network itself is still in poor condition. Burundi and Rwanda are also connected by paved highway to Kampala which has a rail link to the seaport of Mombasa.
