Wikipedia has a page about Braunston Tunnel
Braunston Tunnel is on the Grand Union Canal about 830 yds (760 m) east of Braunston, Northamptonshire, England top lock. It is in the northern outskirts of Daventry, about 2 km east of the village of Braunston.
Braunston Tunnel is 2,042 yards (1,867 m) in length. Built by Jessop and Barnes, the tunnel has no towpath and is 4.8m wide by 3.76m high.
It was opened in 1796. Its construction was delayed by soil movement and it was probably the resulting movement that led to the tunnel having a slight 'S' bend. There is room for two 7 ft (2.13 m) 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.
