Markerposts are meant to start at one end of a road and count the kilometres to the other. But things are never that simple.

The A625 used to cross the Peak District - then nature got involved. Now the slopes of Mam Tor are accessible only on foot.

The A52 Clifton Bridge's major emergency repairs are bringing chaos to Nottingham. What's gone wrong - and how could it be a total surprise? Civil engineer Alex Romankiw explains.

Nobody likes a concrete road. Promises have been made time and again to get rid of them all - but perhaps there’s another solution.

The A90 Aberdeen Western Peripheral Route is the biggest road construction project the UK has seen for years - but there's something very wrong with the bridge over the River Don.
