What happens when there's a big accident on a trunk route? Who picks up the pieces, and why does it take so long?

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.

Those last few miles of the M1 east of Leeds were completed in 1999. It looks for the most part like a fairly average piece of road, but one of the project's engineers describes some of the challenges that were faced.

The 1920s and 30s saw a huge roadbuilding boom in London's suburbs. Some of those roads are incredibly well known, but here are five Arterial Roads that have been almost completely forgotten.

There's almost no evidence of Liverpool's 1960's plans for an inner ring road on the ground - but the motorway that never materialised would have been astonishing. The full details on the route, and the missing part the M62, are here.

Even in the 1960s heyday of roadbuilding, some people said you could never build your way out of congestion. Glasgow had plans to prove them wrong.

Today you can catch a train to France. You can even put your car on it, and be there in less than an hour. But in the 1980s, Euro Tunnel had competition - including plans to build a motorway across the English Channel.

Those funny black and yellow symbols are everywhere - and they might just get you back on track one day.

If you're on the motorway (in England at least) you might have noticed some funny blue signs down the side of the road. What are they for?
