Portskewett railway station is a former station serving Portskewett, Wales, four miles south west of Chepstow and one mile east of Caldicot. It was opened as a broad gauge line with the South Wales Railway in 1850 and closed to passengers in 1964. Between 8 September 1863 and 1886 the station was known as Portskewett Junction, where the Bristol and South Wales Union Railway diverged for the New Passage Ferry crossing to Bristol. This new station was at a location 800 yards east of the original location. The opening of the Severn Tunnel in 1886 made the ferry at Black Rock redundant. The station was twin platform with a footbridge. The footbridge and the twin track line remain in use today. Portskewett Pier railway station was opened on 1 January 1864 and closed 1 December 1886.

Portskewett Pier was a station on the Bristol & South Wales Union Railway. The pier at Black Rock, near Portskewett, was the Welsh side of the New Passage Ferry across the River Severn. The ferry linked rail services between Bristol and South Wales, avoiding the previous long detour through Gloucester. The ferry service lasted for nearly twenty five years, from 1863 to 1886, until the opening of the railway tunnel beneath the river.

The Second Severn Crossing (Welsh: Ail Groesfan Hafren), officially named the Prince of Wales Bridge (Welsh: Pont Tywysog Cymru) since July 2018, is the M4 motorway bridge over the River Severn between England and Wales, opened in 1996 to supplement the traffic capacity of the Severn Bridge built in 1966. The bridge is operated by England's National Highways. It has a total length of 5,128 metres (16,824 ft). It is southwest of the Severn Bridge and because it is more closely in line with the rest of the M4, it reduces the length of the journey between England and Wales. The junctions at each end are designed for most traffic to use this crossing, and in order to use the old Severn Bridge, one has to leave the M4 at junction 21 and join the M48 near Aust or at junction 23 near Magor. The new crossing carries more traffic than the Severn Bridge, which is still in use. It is wider than the Severn Bridge, having three lanes and a narrow hard shoulder each way, compared to the two lanes, cycle path and narrow footpath of the original crossing. It is a cable-stayed bridge, whereas the Severn Bridge is a suspension bridge. The position of the bridge is close to that of the Severn Tunnel, which has carried the railway line beneath the river bed since 1886. Much of the estuary is mudflats at low tide, but at high tide these can be covered by as much as 14 metres (46 ft) of water. This presented the engineers with a constraint: packets of work were scheduled at low tide, and needed to be completed within the short windows allowed by the tides. The concession given to the consortium which financed, built and operate the bridge required them to take over the outstanding debt on the original Severn Bridge and to operate the two bridges as a single entity. Tolls were set annually by the government based on the previous year's change in the Retail Price Index. On the expiry of the concession in January 2018, the consortium was required to hand the bridge over to public ownership. The tolls on both bridges were subsequently scrapped in December 2018.
