This was looked at many years ago, the stumbling block was the need to get deliveries to the shops some of whom do not have access from other roads.
It was the fashionable thing to do then.
Not sure if it has been found to aid the High Streets in general or just turned ithem into an un-used wastelands.
Having said that it would be useful to have views not only on possible pedestrianisation but also what else it is possible and legal to do to keep the High Street thriving and used with lots of people walking along it.
What about the trhough traffic? I think everyone in Portishead is aware of the lack of roads and this would just cause high volumes of traffic using back roads.
The idea is good though although I suppose we do have that kind of area around Waitrose, only problem being its not the high street.
How about later opening? Its like a ghost town at times as there is no need for people to be on the high street after 6pm unless they are going to a pub or take away.
I would be tempted to bypass the High Street entirely if this happened. I would approach via Avon Way-as would anyone from above the High St-I would then turn left and head straight to Waitrose or out of town ! It would be a disaster I think for the High St. With little parking and the congestion in the back streets as much as it sounds nice it would do more harm than good. Regarding access to shops-you cannot have access where there is none but for the High St-unless you did something like Clevedon has. Clevedon has the square though so it works-it would not work on this section of the High St.
