The M25 Runnymede Bridge is a motorway bridge built in the 1980s, carrying the M25 motorway across the River Thames. It carries the M25 North/South just south of Heathrow Airport and crosses the Thames on the reach above Penton Hook Lock and shortly before Bell Weir Lock.

The bridge was built to complement an earlier bridge built by Sir Edwin Lutyens [ [http://www.iht.org/motorway/m25papers4.htm The Motorway Archives] ] a low wide arch bridge built of brick to carry the A30 Staines By-pass. It is an open spandrel arch of the same basic shape, but is made up of a series of parallel concrete frames. These allow light to penetrate underneath and transfer loads vertically to avoid disturbing the foundations of the earlier bridge. The motorway bridge was recently widened to six lanes each way. It is one of four bridges carrying motorway traffic across the Thames, the others being the QE2 Bridge, the M3 Chertsey Bridge and the M4 Thames Bridge, Maidenhead.
