The M57, M58 and 3 A roads converge at the Switch Island, making it one of the busiest motorway junctions in England.
Connected to the traffic lights through an automatic controller unit, the LED road studs illuminate when the traffic lights turn green to guide drivers with the lane that they should follow.
These studs can be visible up to 1,000m away and prevent drivers from changing lanes thereby reducing the risk of collisions.
Highways England project manager Phil Tyrrell said: “We’re always looking for new ways to further improve journeys and safety for drivers, and I hope the new intelligent road studs will help better guide drivers around Switch Island.
“The innovative light-up road studs, along with the other improvements we’re introducing, will make it much easier to navigate the junction, benefitting the tens of thousands of drivers who travel through it every day.”
Construction work on the £3m scheme, funded from the government’s £220m congestion relief programme, is expected to take one year to complete.
Under the project, new traffic lights will be installed at a height of more than 5m so that drivers can clearly see them.
The scope of work also includes changes to the road layout and lane markings, building new barriers between carriageways, coloured high friction surfaces and better signs.
An additional 400m shared cycle path will also be created through the junction to connect the existing cycle path alongside the A5036 Dunnings Bridge Road.
Highways England recently completed the installation of LED studs at Hindhead Tunnel in Surrey.
