I wonder what GNE has planned, run the 20/20A so far and terminate them before at Belmont and run some sort of shuttle? or otherwise theres not going to be any buses between south shields and sunderland if the 20 gets delayed as their will be long tailbacks etc..., just have to see when GNE announcing on their facebook page or website.
The route change on service 204/208/265/865 will be due that claypath sliproad will be closed.
