| Information | |
The M3 Chertsey Bridge is a motorway bridge across the River Thames between Middlesex and Surrey. It was built in the 1970s.
Purpose
The bridge carries medium-distance traffic along the M3 motorway between its first and second junctions across the Thames at its north-south reach above Chertsey Lock.
The bridge is 330 yards upstream of the lock and 500 yards upstream of taller Chertsey Bridge, the short-distance traffic bridge of Chertsey across the river, which is a stone-built listed structure — restored and strengthened in the early 21st century, humped and subject to an 18-ton LGV use restriction. It was erected in 1785, replacing an earlier bridge on the site.
It is one of three bridges carrying motorways across the Thames, the others being the M25 Runnymede Bridge and the M4 Thames Bridge at Maidenhead.
