Work on junction 25 of the M25 will continue this week.
The project will be reconfigured to improve traffic flow. The A10 southbound approach into the junction is also a congestion hotspot in Broxbourne, according to Highways England.
Junction 25 already sees up to 6,300 vehicles per hour using the junction’s roundabout at peak times, causing congestion and regular delays.
Highways England Project Manager Indy Grewal said: “We’ve been busy working on developing the design and construction plan since our last public information events in June 2019 where peoples feedback helped shape our approach to delivering the scheme.
“Improving this junction will mean better journeys for the 6,300 drivers who use it every hour at peak times; it will also increase capacity and help to boost the economy.”
Most of the main construction work will start in February and will continue until summer 2022. This will include the widening of the roundabout to include an additional lane-which will be a free-flow left lane from the M25 west off slip road on to A10 north. There will also be the widening and extension of the M25 westbound off slip and a widening of the M25 eastbound off slip road and the A10 southbound at the entry to the roundabout, as well as improvement on the existig subways and new shared use routes for cyclists and pedestrians.
