|Route outline (key)|
The B3166 is a short road running between North Camp and Ash Vale on the Hampshire / Surrey border. It was originally the eastern end of the A3011 but was downgraded following construction of the A331 in 1995.
The route starts at the eastern roundabout of the A331 / A3011 GSJ and heads east, crossing the River Blackwater and the Blackwater Valley Line above North Camp station, to reach a roundabout junction with the B3165. Here we bear right and follow Lysons Avenue, passing through an industrial estate before the road becomes residential as it enters Ash Vale and ends at a mini-roundabout on the B3411.
The initial stretch of the B3166 between the A331 / A3011 and B3165 junctions – which today crosses the railway at North Camp via a flyover – dates from circa 1990 and replaces an earlier alignment (of the then A3011) which ran a few metres to the south and crossed the line on the level. The level crossing remains in use – it is said, largely to avoid the cost of providing a pedestrian bridge (with lifts, as would be required by modern access legislation) at the station. The old road is now used chiefly to provide access to the station, although a prominent notice at the western end seeks to dissuade Satnav-led HGVs from using this route to gain access to the industrial estate on Lysons Avenue.
