M4 Corridor around Newport

M4 Corridor around Newport

Proposals for the M4 Corridor around Newport motorway involved a 22.7km re-routing of the M4, from Junction 23 (east) to Junction 29 (west), to the south of Newport. The project involved major junction works, stretches of new carriageway across poor ground in ecologically sensitive areas, plus significant viaducts and bridges over the River Usk and Newport Docks.

In March 2015 Welsh Government appointed CVJV (the Costain, Taylor Woodrow and VINCI Construction Grands Projets joint venture) on an Early Contractor Involvement (ECI) contract to assist in developing the scheme through its early stages. This involved developing a Preliminary Design followed by preparing and publishing of Draft Orders and the Environmental Statement for the scheme for presentation at the Public Inquiry to enable all views to be considered.

The Planning Inspector concluded there was a ‘compelling case for the scheme to be implemented in order to relieve an acute problem on the strategic motorway network’ he also said. ‘The scheme would not, to my mind, have any disproportionate adverse impacts.’

However, Welsh Government decided that cost and environmental impacts were too great for the project to progress through to construction.
