The River Kent is so low you can walk in it to take a picture of this bridge which I find is a scheduled ancient monument. It's not that old - built in 1818. There have been bridges on this site for centuries linking the town to the castle corn mill but most got washed away by floods. The first stone bridge was built in 1743 but it was deemed to narrow for the increased traffic they expected to get when the Lancaster canal arrived so they built this one in 1818. Just as well really, the canal was short lived but the bridge is wide enough for 20C cars. Although the width may be the reason for the one way system, in the town that is so complex I can only just about manage to navigate the town without sat nav and I've been here 2 months.
