MartinR, GSV is pretty rubbish sometimes at where named sections of road change. Once again the Post Office has history in this regard. For over 30years we lived in Headcorn Road, but maps always put us in Lenham Road. Never did get a definitive answer as to where each finished and the other began.
If you street view the old cinema you will see the road name sign "High Street" to the right of the building as you look at it. Constitution Hill ran from there up and into Paddlesworth Road, but the junction with Birling Road was changed to make that the major(!) route so making Constitution Hill a dog leg.
The cinema was a Bingo Hall when we played with its old Potterton BOA oil boiler in the 1970s. The place was very run down, and getting paid was an adventure. Since been a Potterty shop and now an antique centre, which got itself on TV recently on one of the Antique Roadtrip programmes - I forget which.
