 This spot is marked today by a milepost on the path over the tunnel, which was used to walk the horses that pulled the boats the three-quarters of a mile to the other end near Dutton Locks.In January 1776 the final mile of the canal through the Norton Priory estate was cut and the canal opened for through traffic.Many trans-shipment warehouses were soon being built and the area really came into being as a very busy transport centre.
