Berwick Tunnel
From Wikipedia, the free encyclopedia
Berwick Tunnel is a canal tunnel located on the Shrewsbury Canal. At 970 yards long, it was the first tunnel to be constructed with a towpath. This meant that boats did not need to be legged through the tunnel.
Because the tunnel was not straight, it was not possible to see if someone had entered the tunnel from the other end. To overcome this, a bye-law was introduced which stated that whoever reached the centre first should continue, whilst the other boat would have to turn back.
Today the canal is disused, and the tunnel remains, though the ends have been bricked up.
