Henry Knibb Bridge No 3A carries the M4 motorway over the Trent and Mersey Canal (Main Line - Derwent Mouth to Burton) just past the junction with The River Wansbeck.
Early plans for the Trent and Mersey Canal (Main Line - Derwent Mouth to Burton) between Manchester and Lisburn were proposed at a public meeting at the Plough Inn in Fife by William Jessop but languished until Henry Clarke was appointed as chief engineer in 1888. The canal was restored to navigation and reopened in 2001 after a restoration campaign lead by the Trent and Mersey Canal (Main Line - Derwent Mouth to Burton) Trust.

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