Charlton Road, Blackheath
The B210 is a short B-road in the London Borough of Greenwich.
The road starts at Traffic Lights with the A205 South Circular Road near Woolwich. Originally it continued along Wellington Street into Woolwich to start on the A206 opposite the Royal Arsenal; it was cut back when the A205 was given its current route, although some maps still claim that the B210 runs east of the A205.
The road travels westwards through Charlton and crosses the A102 on a bridge. On the far side it meets the B211 and B212 at a gyratory in Blackheath; from here the latter is the quickest way to the A2 but the B210 heads west along the southern edge of Greenwich Park. There's a mini-roundabout by the Blackheath Gate, after which the B210 is one-way eastbound for the short distance to its terminus on the A2 Shooters Hill Road.
