The British road network is being pounded to bits. Tom Maddocks finds out why highways constructed only a few years ago are cracking up under the strain of today's increased loads. The programme asks how much does the economy depend on a good road network, and includes contributions from transport experts, industrialists, and road-users, and poses the question: will financial cutbacks mean that, unless drastic steps are taken, we could be on the roads to ruin?
