The canal is 127.25 miles long and flows from the inland woollen town of Leeds to the coastal sea port of Liverpool, crossing the Pennines along the way. Work on the canal started in 1770 and built in a number of sections and was finally completed in 1816.
This bridge is a stone bridge with two round arches one above the other, designed by Robert Whitworth. and is a Grade II English Heritage
listed building. It carries A59 over the canal where the canal passes through an unusually deep gorge and was built around 1790 when the canal was extended from Gargrave to Burnley.
The bottom arch is a strainer arch and is required to help support the unusually high abutments.
Like many of the bridges on this canal the arch stones are painted white to help boat owners judge their approach through the bridge. In addition because the bridge straddles the tow path on one side of the canal the bridge keystone is not in the middle of the canal. The canal is quite shallow along this stretch and so a vertical white line painted on the bridge parapet indicates the middle of the canal itself, the deepest part of the canal.
The bridge is on a slight bend in the canal and when horses were originally used to tow the canal boats, grooves were cut into the arch. To prevent this a wooden post was attached to the arch of the bridge to protect it.
