At Tadcaster there is a very fine bridge over the river Wharfe, some 300 yrs north of the town centre road bridge. It used to carry a goods line off the Church Fenton to Wetherby line, serving a factory on the east bank of the river.
The main town bridge collapsed in floods on 29 Dec 2015. It cut the town in half. It took 13 months and £4.4 million to rebuild it. Ironically the old railway bridge withstood the flooding, but carries nothing. Built of Magnesian limestone it still looks impressive. I don't know if it is possible to cross it on foot.
