Discover Over Bridge

The medieval bridge at Over was replaced in the Tudor period by an 8-arched stone bridge. By the 19th century the Tudor Bridge was proving to be an obstruction to river traffic due to its narrow arch spans. Then in 1818 the Tudor bridge was damaged by ice, and the city decided it was time to replace it with a modern bridge that allowed better traffic flow on land and by river. They called in Thomas Telford (1757-1834) to design a new bridge, with a single span to avoid obstructing river traffic.

Two designs were presented, one cast iron and the second in stone. The city council decided that the cast iron bridge was not dignified enough for the main western approach to Gloucester, and opted for the stone design.
