SPACE for Gosforth has already covered the impact of the bollards in a separate blog: https://www.spaceforgosforth.com/we-still-love-gosforth-high-street/

To answer your points though:
– The main constraint to traffic flow of Gosforth High Street is other traffic, not bollards. Specifically traffic travelling east/west at the Salters Road junction which is substantially unchanged.
– The High Street has three separate car parks. If these are full that may suggest they are under-priced. Certainly it is cheaper to park for a few hours than get the bus.
– Most recent shop closures reflect national trends, for example closure of local bank branches. This is nothing to do with the Council.
– We agree with the need for a radical plan. Big changes are needed to ensure Gosforth High Street is safe for all users, has clean air and is a great environment for people shopping.
