Traffic in a mid 1950s town

A photo of traffic at a junction in a town taken sometime in the mid 1950s or possibly the early 1960s. The road to the left looks like it is a bridge, and the lights may give a clue as to the location.

When I zoom in on the car number plates, none seem to have a registration letter which is why I think this may have been taken in the 1950s rather than the 1960s.
