A £90,000 Highways Agency project to upgrade traffic lights at eight locations along the A595 in Cumbria is currently underway.
The existing lights are being replaced by new energy-saving LED signals, which will be more visible to drivers in bright, sunny conditions and should require less maintenance.
Traffic lights at junctions as well as at pedestrian crossings are being replaced in a rolling programme of works which started on Saturday at Calderbridge junction near Sellafield and is due to be completed by Friday 3 February.
Peter Gee, Highways Agency project sponsor said: "There may be some delays for drivers while we carry out the work but there should be a long-term benefit, with the brighter lights helping to improve safety for drivers, pedestrians and other users of this route.
"The new LED lamps are also better for the environment and will help reduce the Highways Agency's carbon footprint."
The remaining works are at:
• St Thomas Cross roundabout at Egremont • Springfield Road pedestrian crossing at Bigrigg • Egremont Road and West Lakes Sciences Park junction near Whitehaven • Egremont Road pedestrian crossing near Rutland Avenue in Whitehaven • Hensingham bypass, Ribton Moor Side and Inkerman Terrace junction, Whitehaven and the Toll Bar pedestrian crossing near the A597 roundabout at Distington.
