One of the problems with that diversion is the number of times that Ross Bridge gets closed, often with little or no warning. It's rarely to do with shipping access to the Dry Dock, or very high tides, more that Cornwall Council wishes to tinker with something, that often gets re-tinkered with the following week: keeps some in employment, i guess! If the bridge is closed, there is no way the Jubilee Pool can be served as there are no alternative roads suitable for full size buses. Westbound buses should have no problem stopping at Jubilee Pool, but for the life of me I can't see anywhere for eastbound buses. Perhaps we'll get a Greenmarket, Penzance situation, where the eastbound stop is known to drivers and regular passengers but has never existed in the form of an actual stop/timetables/bus stop markings on the road.
