Further restrictions are in place on the future Olympic Route Network in west London this week as the Highways Agency has been forced to impose weight limits on the M4.
The Agency introduced a 17t weight restriction between junctions two and three on the motorway following a routine inspection of the Boston Manor viaduct just west of junction two. The 19.4m long steel bridge was built in 1964.
This latest disruption comes just a few months after serious corrosion was discovered on the nearby Hammersmith flyover forcing its closure over Christmas and leaving it with only one lane open in each direction to light traffic while repairs continue.
The Boston Manor viaduct forms part of the Olympic Route Network connecting Heathrow in the west, with central London and the Olympic Park in the east.
