They only removed part of it - and the one on Georgia is still there.
It could be that they are refurbishing/replacing the signs with similar ones.
I noticed the one facing Georgia was backlit last night, and I can't recall if they had been backlit before.
In the pics above, the Georgia one seems to have heavier font than the Seymour one - i.e. to accommodate lighting.

Seymour was closed off today for a lift of some kind with a big mobile crane in the street.
Could be for VCII signage?
