Wales

Two lanes each way don't make a dual carriageway. What does? Let's go to Wales and find out.

The A40 travels more than 260 miles west from St Paul's Cathedral in London. This is what a journey along its whole route, from start to finish, looks like.

Upgrade work on the A465 through the Clydach Gorge is taking longer and costing more than expected. Should lessons have been learned from the last engineers to take it on?

The A465 Heads of the Valleys Road is one of the most spectacular trunk roads in the UK, and building it required some of the most remarkable civil engineering. This is the story of how the road was built in the 1960s, and how it's being rebuilt today.

Today two motorways cross the Severn near Chepstow. But as recently as 1965, the only crossing was a ferry that carried six cars at a time, from Aust to Beachley.

The road that connects Wales together, but which nobody really uses... All five hours of the A470, from Llandudno to Cardiff, are here.

One man's account of the building of the M4 through Wales, seen as he grew up in Swansea and witnessed it stage by stage - a tour of the motorway from its construction to the present day.
