Trunk roads: the T1 is known as the TANZAM highway and leads from Dar es Salaam to Zambia (and on to Lusaka). The road from Chalinze to Kenya is the T2. The main road from Dar es Salaam is the T7. Other 1-d roads are mostly main national links. Higher numbers are used for less important roads. Regional roads have 3-digit numbers. They are almost never paved. | ||||||

| History: Until the 1980's, there was a joint A road numbering system with Kenya, and B roads. Then a new system was introduced with A numbers. Only very few numbers in this system are known:
A1 Dar es Salaam - Chalinze - Moshi A6 Chalinze - Morogoro Probably around 2000, the current system was introduced. It is not known whether any or all signs have been adjusted. | ||||||
