Hello Croydonian,
Welcome to Rootschat.
My brothers were at East Street, just before it closed.
All that area in Maidenhead has been flattened. East Street joined to Market Street which is the beginning of the Cookham Road.
Hope that makes sense, as you could find it on Google earth.
There you will see the town by-pass. The middle roundabout is the Cookham road.
I hope to go to Maidenhead tomorrow, if you need something looked up....
Best wishes,
Lesanne.
