1. Pavements that are safer to walk on (because they don't stick up all over the place)
2. Double yellow lines to prevent illegal (and legal parking) on a narrow main road
3. Buses that serve the town centre to encourage use of buses and of local shops

Beyond this I hope that a better strategy for shops to load/unload can be implemented, and there may be very slightly more parking spaces (but not many). I'm also hoping that the aesthetics of the high street will be improved with so much money spent on it.

Those are fairly limited benefits, but they are nevertheless benefits. It would have been nice to achieve more with £600k, but sadly I doubt anything more radical would get the support of the traders, neighbours, drivers, or bus companies.
