More bus lanes in Norwich will be monitored by cameras in a bid to catch motorists who drive into them.

Norwich City Council's highways committee agreed on Thursday for traffic regulation orders to be updated to enable all bus lanes to be enforced by camera.

A report presented to the committee said since the introduction of cameras on St Stephens Street there had been a 90pc reduction in unauthorised traffic in the bus lane.

Camera enforcement is already planned for Brazen Gate, which is likely to be operational in coming weeks. Earlham Green Lane, Bowthorpe, is also proposed for enforcement, though the council could also look at several other areas in future.

Updating traffic regulation orders to make them compatible with camera enforcement will cost £1,000.

Once all cameras are in place, it will cost £2,000 to move them to a new location.
