Blisworth Tunnel is a tunnel on the Grand Union Canal between the villages of Stoke Bruerne (southern end) and Blisworth (northern end). At 3076 yards (2813 metres) long it is the third-longest navigable canal tunnel on the UK canal network. Construction started in 1793, but after three years work it collapsed due to quicksand, claiming the lives of fourteen men. It was then decided to begin again with a new tunnel, which was not complete until March 1805, five years after the rest of the canal was open. The gap was filled by a temporary horse-drawn tramway over the top of the hill, with goods being transported from boat to wagon and back again. The tramway, built in 1801, was Northamptonshire's first railway.
