The M4 was closed in both directions between junctions 8/9 and 6 last weekend (November 15 to 18) for the demolition of Marsh Lane Bridge.

The road underneath currently only has three lanes on each side which is not compatible with the new smart motorway design, meaning a wider bridge is required as many of these bridges were originally built in the 1960’s.

There is another full weekend closure of the motorway planned later this month between junctions 6 and 8/9, over the weekend of November 29 to December 2.

Full details of this closure will be available nearer the time.

The work is part of a project to convert the M4 between junctions 3 and 12 to a smart motorway.
