Last summer when Blackett Street was closed each weekend in summer, Go North East amended their Next Stop Announcements on service 21, advising passengers that the next available stop would be St. Mary's Place. It was given as an alternative destination for drivers to use, so that the normal route could still be announced during the week.
Obviously Blackett Street doesn't affect Go North East nowadays - only really affects Stagecoach, who don't provide Next Stop Announcements on their buses (yet) anyway.
My bad. Forgot about Blackett St, but hopefully you get the gist.
The fact it was temporarily rolled out on the 21 last summer, really emphasises the ability to do it for other services that are affected by closures.
