M40 J15 Longbridge Island

Scheme outline

Improvement to the existing roundabout interchange (currently featured in Bad Junctions) by providing a bypass for A46 traffic. The finished layout will effectively be a three-level stacked roundabout but instead of building the A46 flyover across the existing junction, it will be built slightly to the north-west.

However, to maintain access between the new road, existing roundabout and the B4463, a roundabout is included in the south end of the A46's new mainline instead of a merge/diverge. The north end is of a more standard design.

This scheme was completed in and we're no longer accepting updates or changes to this page.

Work on the junction is now expected to commence in April 2007.

The Secretary of State has now approved the scheme following the end of the public inquiry, and construction is now due to start in March 2008. It is thought that funding has been allocated but not formally announced yet.

Work is now under way on this project, with the first phase to build the new bridge over the M40 north of the roundabout. The completion date is now estimated at 2010.

23 January 2009

Work is still progressing with some closures and narrow lanes on the M40. New gantries are also visible through the work site.

23 September 2009

The new bridge over the M40 is substantially complete and the Highways Agency have announced that the bypass is to be opened by Christmas 2009. Northbound A46 traffic is already using the new bridge.

14 December 2009

The new bypass bridge over the M40 was opened to traffic today. Work will continue on improvements to the roundabout into 2010.

12 June 2010

Scheme, in the main, is now completed. Weekend closures for residual works still taking place. The main motorway junction roundabout still has works taking place with frequent lane closures for remodelling.
