Road linking St Mary Cray with Petts Wood. Old maps show a narrow lane leading from St Mary Cray to Poverest Farm, situated where Poverest Baptist Church (see
TQ4667 : Poverest Road Baptist Church) now stands. However, although the present road followed the route of part of this lane, the section here was on the route of a footpath, the original lane following the route of what is now Marion Crescent.
The area was developed before or after the Second World War, although exact timing is unclear: the 1944 Kent XVI NE 6" map based on 1938 revisions has housing shown in outline, whereas the 1946 London Sheet T also based on 1938 revisions still shows open countryside. The former map shows this section as Sherwood Road, consistent with the Robin Hood theme of much of the area, with the Poverest Road name still being applied to the then largely undeveloped Marion Crescent. By the 1960s, the names had changed, presumably reflecting the through road status of Poverest Road.
