The canal was started from the Derwent end, so that sections could be brought into use as they were completed. Work progressed quickly, and some of the shareholders protested at the frequency with which calls were made for the money, but a fast build reduced overheads. The section to Hagg Bridge opened in August 1816, and the head of navigation was extended to Walbut in the following spring. Bad weather prevented Leather from completing the work by the end of 1817, and the canal eventually opened on 30 July 1818. The final cost was £32,695, the excess over the original estimate being caused by some additional works which had to be done. £2,495 was borrowed to cover the shortfall, and Leather received a warm vote of thanks from the shareholders.
