Guildford will be the first non-motorway location in the country to trial “smart” traffic lights.
The new lights will be installed at the A3 Dennis Interchange and will monitor traffic flow and adjust their timings appropriately, Guildford Borough Council says.
It will mean a series of overnight road closures on the A3 while the lights are installed and other improvement work is carried out by Highways England.
Councillor Matt Furniss, lead councillor for infrastructure and governance at Guildford Borough Council, said: “We are very pleased that Guildford has been chosen as the first place in the country to trial these new traffic signals, which aim to bring benefits to all local residents and visitors who use the A3 Dennis Interchange.
“We are committed to working with partners to improve the borough’s transport infrastructure and hope the new smart traffic signals will help improve traffic flow at this busy spot on our road network.
“We are working with Highways England and Surrey County Council to help improve journey times prior to the Roads Infrastructure Scheme A3 upgrade.”
The borough council says it will be the first non-motorway trial of the new traffic signals. Dennis Interchange is the junction near the Guildford business park, which enables motorists to access the southbound A3, and northbound A3 users to come off the motorway.
The lights will include LED technology to help reduce their carbon footprint.
Lane closures will be in place at the Dennis Interchange overnight, between 10pm and 6am, on Tuesday (March 20) and Wednesday (March 21).
The A3 southbound carriageway from the Stoke Interchange to the University Interchange will be closed overnight, between 10pm and 6am, until Friday (March 23). A clearly signed diversion will be in place via Guildford.
The northbound entry slip road at the Burpham Interchange will be closed overnight, between 9pm and 6am, from Wednesday (March 21) for three nights. A clearly signed diversion will be in place via Guildford.
