The JV won the £27.3m contract back in January 2015, since when design details have been worked up. The overall project cost is £57m, the Welsh government says.
The new dual carriageway, designed by Capita and Cass Hayward, will provide a more direct route between the east of the city (Roverway) and Cardiff Bay (A4232 Butetown Tunnel), alleviating congestion around Tyndall Street.
Utility diversion and preparatory work to build the new Eastern Bay Link Road had already begun but the official start of work was signalled by a visit to the site yesterday (17th March) from Welsh transport minister Edwina Hart.
Completion is expected by spring 2017.
