The B213 is an alternative route between Woolwich and Erith.
This shortish road starts at a traffic-light-controlled crossroads on the A206 near Bostall Woods in South East London. Basildon Road becomes McLeod Road around a bend. Both are wide enough to act as a bus route. At a roundabout junction with the A2041, the road cannons by taking the first exit, then takes a turn under the elevated and dualled part of the A2041.
Abbey Road is next and that is initially wider still, marked out as a bicycle lane running on the outside of a lane designed for parking and still space for two running lanes. After a section with two lanes and wide central hatching we reach Belvedere, where there is another section with four lanes plus a cycle lane, this time with a central reservation, so an urban D2. Here we meet the B250 heading off to the right then pass a DIY superstore to a roundabout where the left turn is the B253.
Just after going over the railway line we reach traffic lights which form the first half of a grade-separated junction with the dualled A2016. Straight across the lights there is a flyover across that road before the road sweeps right and negotiates a local roundabout to reach a second roundabout and the other half of the junction with the A2016, where the B213 terminates.
