The QEII Bridge at Dartford carries 150,000 vehicles per day and is one of the busiest sections of road in the world.
Jackson recently replaced the six original multi element expansion joints, which were installed when the bridge was built in 1991.
Due to the sheer volume of traffic that relies on the Dartford Crossing every day, the team had to devise a clever method which kept the bridge open.
The solution was a bespoke designed and built temporary expansion joint, which could be installed during a single night closure over the existing joint. Work to remove the old joint was then carried out during the day, from the underside of the bridge. The new joint was then installed, again, during a single night closure which meant that disruption to traffic was kept to an absolute minimum.
