That looks roughly as it was proposed when I was a parish councillor in Kewstoke, on the route. Controversial with local farmers but not residents of WsM. It will turn a 16 mile journey into a 4 mile journey!
It seems like a disgrace that it has taken about 45 years of campaigning by some very committed local residents, with the creation of the England Coast Path being what seems to have finally pushed it through because otherwise that would use a long stretch of fairly poor A road to reach the next nearest walkable bridge at Hewish, in sight of the M5.
