The A40 originally crossed the area on a causeway and met the A417 at a T Junction.
The A40 was dualled in the early 1970's and was rerouted slightly onto a new causeway and met the A417 at a new T Junction.
At around the time of the dualling there were plans to build a northern bypass for Gloucester to replace the existing bypass which had become urbanised. Designs from 1972 included grade separated junctions. The junction at Over was to consist of a limited access partial freeflow interchange which provides all movements to and from the west but with no access to the bypass from either of the A417 directions.
The bypass was eventually built with roundabouts so Over Roundabout was born. Unlike the earlier design for an interchange, the roundabout allows traffic from all directions to use the bypass. The existing westbound carriageway of the A40 where it rounds the curve was retained as a filter lane to avoid the roundabout. The same curve would also have been utilised as a slip road in the earlier grade separated design.
