Highways Agency - Safe roads, Reliable journeys, Informed travellers

Update

Construction work started on 17 March 2008 and was completed on 18 June 2010. The work was undertaken in two phases: Phase 1 of the project, the A46 bypass of junction 15, was opened to traffic on Monday 14 December 2009.

Phase 2 of the work, which included widening and upgrading the existing roundabout at junction 15 to  reduce congestion at this busy junction, was completed and opened to traffic on Friday 18 June 2010.

A plan of the published route and the latest progress photographs can be found on the Photo Gallery and Aerial Plan page.

The Project

The completed scheme forms a dual carriageway bypass of the M40 Junction 15, allowing vehicles travelling on the A46 to avoid this busy junction. The bypass is routed to the west of the junction and connects to the existing A46, north and south of the motorway.

The northern connection between the new bypass and the A46 Warwick Bypass is a two level free flow link. A new 4 span bridge was built to take the new dual carriageway over the M40 motorway. The southern connection between the new dual carriageway and the A46 Stratford road is a roundabout, which also provides access to the B4463 and M40 Junction 15. The roundabout includes underpasses to allow the safe movement of farm vehicles and non-motorised users under the A46.

The existing M40 Junction 15 roundabout was widened to 4 lanes, the approaches to the roundabout have been improved, and new traffic lights installed. The signing, road markings, road lighting and road pavement have been updated to improve safety and driver understanding. The works also included earth mounding, noise fencing, landscaping and improved drainage measures to minimise the effects on the surrounding area.
