There is a marked ASL at the North End of Upper Orwell Street with a marked cycle lane leading up to it.
However, this end of Upper Orwell Street is very narrow and traffic turning left into it from St Helens Street at an acute angle often swings wide encroaching into the ASL. Very large vehicles making this turn would probably have no choice but to do so.
This makes the ASL a dangerous area for cyclists and I would generally avoid using it.
The junction either needs to be revised to avoid this issue and protect cyclists waiting in the ASL or a one-way motors / 2 way cycling system considered.
