Didn’t know this, thanks for the heads up
I only knew because I was stuck behind a bus on the single lane roads, and it had a poster on the back that you could only read if you were close behind.
Some are probably still paying.
I think the Ulez warning signs, that were fitted over the ones now and removed on the day, cost TFL 26 million, and they did not get the scrap money for those removed.
This fiasco if you include 3 different new lots of signs, will not be far short.
