When I left Chesterfield in 2002 Beetwell Street bus stop were open and not enclosed by glass. Does anyone know or a rough guess when this change happened and why this was done. On a recent visit to Beetwell Street car park was going down that ramp that leads onto Beetwell Street . I noticed a very old sign on the wall a bit faded it shows the glass shelters and white buses I don't recall this at all perhaps its just a imaged scene I don't know but got me curious that's all ?
