Longbridge Island was one of many suggested sites for services on the M40.
In 1981, Esso put forward an application to build a full motorway service area at J15. At the time the M40 wouldn't have been built, but would have been under construction without any planned services. Even then this would have been a busy junction, housing the Warwick Southern Bypass, but today it is much busier and a service area would be unworkable.
Back in the 1960s, Warwickshire Council had remarked that they would have liked to have built a TRSA on the A41/A46 Warwick Bypass, but they didn't have the authority to do so. Esso's proposal wanted to turn that unfulfilled idea be turned into reality.
For a while it was suggested that the nearby Budbrooke services could be used as an alternative to building any new services here.
The site was later used to provide temporary facilities until Warwick services was built.
