On the A27 in Hampshire, time is running out for road gangers Steve and Robbie. They have an epic resurfacing of a dual carriageway to carry out – but it hits the skids when the late arrival of the cone lorry needed to shut off the road is closely followed by the no-show of the tar truck. In Essex, site manager Steve has a bold plan to build a new slip road and pedestrian subway under the busy Army & Navy roundabout. But could the million pound job be in danger of folding because of some specially moulded concrete blocks not fitting together like Lego as planned? And in Hampshire, likely lads Mike and Russ are in a race to stop a busy country lane cut-through falling apart at the seams – and an unsuspecting motorist ending up in the hedgerow as a result.
