M25 reopens after a damaged bridge near Junction 3 brought traffic to a standstill

Vehicles were redirected off the M25 and back on at Junction 3

Emergency repair work to a damaged bridge on the M25 brought traffic to a standstill today, with motorists forced to use alternative routes for more than five hours.

As teams worked to repair the bridge, it meant that Junction 3, where the M25 meets the M20 had to be closed.

This led to traffic backing up on the QE2 bridge and clockwise London Orbital, to the Dartford Crossing.

The diversion caused traffic to tailback for over 10km.

While contractors carried out an emergency inspection, cars were forced off the motorway slip-road and then re-joined the motorway. The process caused over an hour of delays to motorists.

Civil Engineer, Bill Harvey, said that as bridges are often exposed to both high and low temperatures, this variation can cause parts to fail.
