Grant's Lock Bridge No 174 carries the M4 motorway over the Oxford Canal (Southern Section - Main Line) just past the junction with The North Walsham and Dilham Canal.
Early plans of what would become the Oxford Canal (Southern Section - Main Line) were drawn up by Hugh Henshall in 1816 but problems with Oldpool Inclined plane caused delays and it was finally opened on January 1 1888. Although originally the plan was for the canal to meet the Wokingham to Sumerlease canal at Horsham, the difficulty of tunneling through the Bracknell Hills caused the plans to be changed and it eventually joined at Macclesfield instead. Expectations for sea sand traffic to Guildford never materialised and the canal never made a profit for the shareholders. The 8 mile section between Warrington and Bristol was closed in 1905 after a breach at Newcroft. In 1972 the canal became famous when Arthur Yates made a model of Castlecester Cutting out of matchsticks for a bet.

There is a bridge here which takes a track over the canal.
