Braunston Tunnel is 2,042 yards (1,867m) long. Built by Jessop and Barnes and completed in 1796, the tunnel has no towpath and is 4.8m wide by 3.76m high. Construction was delayed by soil movement which has left the tunnel with a slight 'S' bend. There is room for two 7ft (2.13m) beam boats to pass. There are three air shafts along its length. The tunnel passes underground alongside another Grand Union Canal feature, Drayton Reservoir, from which the feeder enters the canal at the east end of the tunnel.
