This tunnel on the Grand Union Canal is wide enough to allow two narrowboats to pass in opposite directions (with care!). Wide beam boats ( up to 12ft 6in) must get permission in advance before entering the tunnel. The tunnel is 2042 yards long (about 1867 metres), and was opened in 1796. Construction was hindered by quicksands. A directional error during the building resulted in the course having a slight S bend. This image shows the tunnel looking eastwards about 100 metres in from the western portal.
