Certainly a major achievement by mankind, this bridge is important, but only impressive if you consider when it was built: Construction began in 1779, and the bridge opened on New Year's Day 1781.
There isn't much to see, but you can walk across and underneath it, making it easy to observe and take some shots of the bridge. There is a tourist information desk at one end of the bridge. There's a site museum, too, which was already closed when I got there. The bridge is said to be open until sun set.
Getting there
This can easily be reached by public transport from Birmingham and other places in the area. There are some buses going from other places near, but I got off at Telford train station and took the bus to Telford bus station. Direct buses depart from there. Make sure to check the return schedule as they don't run frequently in the evening.
