Having served as a main tributary road for commuters accessing London from the M3 for decades, the multi million pound project to prolong the life of the 768m long viaduct, which was built in 1975 has been funded by Transport for London.

The 8 month long scheme allows for the replacement of all of the bearings on the piers supporting the viaduct, as well as numerous other improvements, including the installation of new safety barriers and the waterproofing and resurfacing of the viaduct itself.
