CHANGES to bus lane signs will cost Sheffield Council £490,000 after a decision to alter their hours.
The cost has been revealed after a request under the Freedom of Information Act.
Weekday operating hours are starting at 7.30am instead of 8am and 4pm instead of 4.30pm.
Coun Shaffaq Mohammed, Lib Dem leader on Sheffield Council, said: “It is absurd to spend nearly half a million pounds on changing bus lane signs whilst threatening to close community facilities like libraries and leisure centres.
“Increasing these restrictions is not only a waste of money, it is unnecessary tinkering that will drive away trade and harm local businesses.”
Sheffield Council said that £160,000 has been spent so far, paid for by Government funding which must be used for public transport.
Sign changes are being made as part of larger projects, officers said.
Coun Leigh Bramall, cabinet member responsible for transport, said: “We are not allowed to spend the money to stop government cuts.”
