The B360 is a short link road in Teddington, west London.
It starts on the A309 and heads west along Shacklegate Lane to cross the railway line. This road is liberally sprinkled with "fake" (i.e. paint-only) speed humps.
The B360 TOTSOs by taking the second turn on the left, opposite the gates to Teddington Cemetery. It continues south along the residential Church Road, ending on the A313 in the centre of Teddington. This road is also lined with (real) humps. The road is not signed at either end.
A-Z mapping (e.g as seen on high resolutions on Streetmap) suggests that the route also extends along the entirety of Shacklegate Lane and across B358 Stanley Road into Fulwell Road. Some historic OS mapping (e.g. Seventh Series and NPE) corroborates this, but both modern OS and original MOT mapping show the route as described above. So it is possible that at some stage during its life, B360 covered this extended route. Any evidence confirming this will be gratefully received.
