The B7018 is a largely rural route in central Lanarkshire.
The B7018 near to Brocketsbrae
The B7018 starts at a T junction on the B7078, Lesmahagow Bypass, towards the southern end of the surviving dual carriageway section. It heads northeast along Eastwood Road, passing Eastwood Farm before crossing over the M74 without a junction. The tiny village of Brocketsbrae lies just beyond, although most of the houses lie off to the right. The route then bears left at a realigned bend then right to find its original route, now severed by the motorway. A long straight across fields leads into the tiny settlement of Dillarburn, beyond which the route becomes windier as it climbs into the hills, passing below a small wind farm. A short straight across the summit offers some great views to east and west across the Clyde and Nethan valleys. The highest point is around 240m before the route starts to descend, dropping down to a crossroads where it bears sharply right.
After a short straight, the route becomes much windier as it descends into the valley of the River Clyde. It winds around the head of a small tributary valley, with views across the Clyde to Lanark, perched on the hillside beyond. Lanark disappears again as the road winds through the wooded area to cross the wee burn, but reappears as the route approaches Linville. The road snakes downhill to ease the gradient past this small village where the houses are stepped down the slope. At the bottom of the hill, the B7018 ends at a T-junction on the A72 a short distance west of Kirkfieldbank.
The route was originally unclassified but had gained its number by 1932. It originally started on the A74, Carlisle Road (now the B7078) further north at Craighead, where a short stub of it survives leading into the garage before being cut by the motorway formation. Beyond the motorway, the old road can again be traced, running up between fields to a gated access onto the current line of the B7018. Indeed, the old white lines survive in the dirt and grass here, proving that this was not a TOTSO junction. The current line follows a pre-existing road, albeit with a couple of bends eased, and obviously a realignment as it crosses the motorway.
