by Chris Fryer A warning to anyone wanting to get to Avon Gorge over the next months. A burst pipe has washed away one lane of the Portway (A4) so the whole road may be closed at the moment. (There´s nothing about it on the AA´s Travelwatch site, but it may be too local for that.)It looks like it is between Main Area and the turning up to Clifton, so is going to cause major tailbacks in both directions. It is going to take months to repair.
