If you don’t know Durham, it is well worth an outing with two big medieval bridges and magnificent cathedral, plus a railway viaduct that will feature here soon. The two bridges, Elvet and Framwellgate carry a now pedestrianised road across the narrow neck of land which isolates the castle and cathedral in a loop of the River Wear. Elvet has a row of modest pointed spans but Framwellgate crosses the river in two enormous segmental arches declared to be 26.5 and 25.1m span. There is actually a third, much smaller, span on the city
side which is now hidden by surrounding buildings.
