Weight limit restrictions.

A 7.5 tonne weight restriction remains in place on the M4 between Junctions 1 and 3 in both directions as a result of ongoing repair work at the Boston Manor Viaduct.

It is very important that drivers of vehicles of 7.5 tonnes or more comply with this restriction, observe the local signing and use the alternative routes available.

If you operate vehicles weighing 7.5 tonnes or more and use the M4 between junctions 1 and 3, please ensure your drivers follow the clearly signed diversion route using the dual carriageways of the A312 and A4. This applies to both eastbound and westbound traffic.

The Highways Agency is working closely with the police and VOSA to ensure compliance with the weight restriction.
