London Bridge Bus Station Closure

Anyone know why London Bridge Bus Staion was closed this morning and through till lunchtime...and if it is still closed or not this evening?

Notices said "due to an incident" the bus staion was closed and everyone should head over to London Bridge itself to pick up their buses but as far as I could see there was no incident...only a crane blocking the exit road being used on the new The Place building!

There was something mentioned about urgent sewer repairs on the TfL travel news feed.

Thanks James for the info....I didn't see any sewer work/repairs being done yesterday lunchtime...maybe I missed something

Sewers tend to be underground.....
