The B7070 follows what was the route of the A725 East Kilbride to Coatbridge road through the centre of Bellshill before construction of the town's bypass in the late 1960s.
The road starts at a modified trumpet GSJ at the southern end of the A725 bypass; there's an additional roundabout on the southbound onslip to serve a housing estate. The three other slip roads come in at a large roundabout after which the B7070 heads northeast along Hamilton Road: a wide, tree-lined avenue with service roads on both sides for the houses. After losing the service roads we reach traffic lights where an unclassified road heads off right to reach the A721. Our road then becomes lined with shops and goes under a railway line near the station.
The shops become more affluent as we continue north, then a further set of lights is reached, where the A721 comes in from the right, although it is one-way towards us. The shops are immediately left behind and we head north past Tesco to a large roundabout, where the A721 bears left and the A775 right. The B7070 regains its number by continuing ahead.
We continue north along the residential North Road, although after a while no houses actually front onto our road. Presently we enter open country, then the road ends shortly afterwards back on the A725. Originally the B7070 was the straight road through the junction, with the A725 having to turn off southbound and merge in (at traffic lights) northbound but the junction is currently being redesigned as part of the M8 extension and so this layout no longer exists.
