Severn crossing is a term used to refer to the two motorway crossings over the River Severn estuary between England and Wales operated by England's National Highways.
[2] From 1966 to 1996, the first bridge, from Aust on the English side to Chepstow, carried the M4 motorway.
Before 1966 road traffic between the southern counties of Wales and the southern counties of England had either to travel via Gloucester or to take the Aust Ferry, which ran roughly along the line of the Severn Bridge, from Old Passage near Aust to Beachley.
The Severn Crossing reverted to public ownership on 8 January 2018, run by National Highways.
[5] The county of Gloucestershire's 2050 Vision was launched in 2018, and contains a proposal for a third Severn Crossing between Lydney and Sharpness.
