Sounds like he's a bit of a bright spark. Are there any favorable diversion routes?
There are with the obvious one taking traffic over Bristol's Downs, a huge grass area above the Avon Gorge with enough room for its own football league that has dozens of pitches. This is also an area where the public love to go walking, cycling and generally enjoying the stunning scenery. Traffic will also route through central areas if they us The Downs.
The Portway usually shuts once a year on Sundays for the cliff sides through the gorge to be inspected. That's a proper reason to close it.There is also another Sunday when it's shut for a bicycle day. It looks as though Mayor Ferguson's latest proposals are for additional closure days.
