An early (c. 1960s) proposal for the junction

Junction 31 of the M4 was a proposed junction intended to serve the Hook Road scheme and the A469. Neither the Hook Road nor the junction were built. It was originally intended that the M4 would take a more southerly line than it does now and the area it would have traversed has since been developed. Attempts the get the junction built re-surface from time to time.
