A scheme to reduce traffic congestion on the M1 has been given the go-ahead.
Officials have said the scheme will benefit all drivers
Some of the busiest sliproads in Leicestershire and Derbyshire are to be fitted with traffic lights.
The Highways Agency said lights on junctions 24, 25, 28 and 29 would help prevent vehicles coming onto the motorway creating a bottleneck.
Similar systems on other UK motorway sliproads have reduced congestion and improve journey times by up to 9% officials said.
The system, known as ramp metering, will be installed on the northbound entry slip roads at Junctions 24, 28 and 29 and the southbound entry slip roads at junction 25 and 29.
Sensors in the road monitor the congestion and adjust the timing of the lights.
Highways Agency project manager Jack Warner said: "We have seen the system work well where it has already been implemented on other parts of the motorway network.
"Motorists joining the motorway may have a few seconds delay at the slip road lights, but there will be an overall benefit for all motorway users."
Work will begin on 4 February and the system should go live in the spring.
