Two fantastic engineering structures, an almost-closed services and a bypassed motorway, all at once!
A48(M)
Heading into Cardiff from the east. But what is the mysterious abandoned carriageway?
A48(M) Llantrisant Radial
Cardiff's other A48(M) - but this time it heads west!
A48(M) Morriston Bypass
Swansea's lost and forgotten motorway
A48(M) Port Talbot Bypass
One of Wales's first motorways, now just a part of the M4.
Newport Southern Bypass
