M4 Junction 31 was a planned junction intended to serve the Hook Road and the A469. Neither the Hook Road or the junction were built. The M4 was originally planned to take a more southerly line than it does now and the area it would have ran through has since been developed. Attempts the get the junction built keep surfacing from time to time.
Early proposal for the junction c1960s
