The M4 near Slough closes this weekend for bridge beam lift.

The M4 will be closed in both directions between junction 4b (for the M25) and junction 5 (at Langley) this weekend while beams for the new Old Slade Lane bridge are lifted into place over the motorway.

The closure is from 8pm on Friday, June 26 until 6am Monday, June 29. The old bridge was demolished in February, and this weekend’s work will involve using cranes to lift and secure pairs of steel beams into place across the carriageway which will form the deck of the new bridge. The new Old Slade Lane bridge is expected to open later this year.

During the closure, long distance traffic will be directed via the M25, M3 and M40, with drivers heading for more nearby destinations following local diversions. All diversions will be clearly signed, but some delays are expected and drivers are advised to plan ahead, leave extra time for their journeys and consider alternative routes if possible.

There are several weekend closures at various points of the M4 during July, a busy month for the M4 upgrade, with five weekend closures taking place on different sections of the M4:

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