M4 London – both directions - weight restrictions in place.

The Highways Agency has introduced a weight restriction on the M4 in west London; between junctions 1-3 westbound and junctions 3-2 eastbound.  These restrictions will remain in place until further notice.

Vehicles weighing more than 17 tonnes will be directed to follow a signed diversion route between these junctions via the A312 and the A4.

The restriction is a precautionary measure after a scheduled inspection on the Boston Manor viaduct, just west of junction 2, identified a possible need for maintenance work.

The restriction is not expected to increase journey times on the M4. Drivers on the A4 and the A312 are advised to keep up to date with traffic conditions and allow extra time for their journeys if necessary.
