The engineering marvel of its day, much altered and maligned ever since: this is the original Mersey Tunnel in all its glory.

From Zebra to Pelican and beyond: the comprehensive history of the development of the humble pedestrian crossing.

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.
