The larger Chalinze - Morogoro Road section forms part of the 921km long TANZAM (Tanzania – Zambia) Highway designated as Trunk Road T1 in the Tanzanian Road Network. The existing road comprises a dual carriageway road from Bibititi road junction to Kimara (13.7 Km) whilst the remaining 94.3 km section from Kimara to Chalinze comprises a single carriageway. The Project requires the construction of a new road, adjacent to the existing road, that will give drivers the choice between paying for a superior toll road, constructed to expressway standards, or making use of the existing road.
