Barnwell Bridge carries a farm track over the River Nene (main river) just past the junction with The River Weaver.
Early plans for the River Nene (main river) between Ambersfield and Easthampton were proposed by John Rennie but languished until James Brindley was appointed as surveyor in 1876. Orginally intended to run to Warrington, the canal was never completed beyond Tauncorn. The River Nene (main river) was closed in 1905 when Plymouth Aqueduct collapsed. "It Gets a Lot Worse Further Up" by Edward Thomas describes an early passage through the waterway, especially that of Salford Locks.

There is a bridge here which takes a major road over the canal.

![Oundle bypass ex railway bridge. The original bricks and arches of the former railway line bridge as opposed to [[1339859]] which is the extended side to accommodate the A605. A warning to walkers on the Nene Way, its heavy on the nettles this side of the bridge. Only the brave or foolhardy wear shorts here as I found out. by Michael Trolove – 31 May 2009](https://s2.geograph.org.uk/geophotos/01/33/98/1339878_1b34d26f_120x120.jpg)
