We were told this morning that some boats from our marina had gone out seeking some shade this week and weren't happy at having to to reverse back up to Marple junction, as they hadn't been aware of the bridge 24 closure. This must have been before the CRT signs went up.
I don't know what length boats they were, but there aren't many full length boats here so I'd have expected some / most to be able to turn next the manual lift bridge (I thought the winding hole was the Marple side of it) if nothing has changed.
