Costain wins Newport M4 junction scheme

16 Jan 15 The Welsh government has selected Costain for a £10.5m contract to design and construct improvements to the Newport junction of the M4 motorway.

The improvements to junction 28 involve the demolition of the M4 westbound on-slip underbridge over the A48 eastbound. A new gyratory system will be built to improve traffic flow at what is a notorious bottleneck.

Costain has been appointed on a ECI basis. Works are programmed to begin in 2016.
