A Costain and Vinci joint venture has been appointed by the Welsh government to provide design development for the 拢750m M4 corridor around Newport.

The proposals would include 24km of new motorway and a 2.5km long cable-stayed viaduct crossing of the River Usk, as well as major remodelling of M4 junctions 23 and 29.

The joint venture includes Costain, which has a 50% stake, Vinci Construction Grands Projets and Taylor Woodrow.

Scheme development work will start immediately, leading up to an anticipated public local inquiry in winter 2016/7. Construction could start in spring 2018.
