Drivers face disruption as part of a key M25 junction is set to close tonight for the first of seven weekend closures.
The clockwise slip road at junction 28 in Essex will be shut from 11pm tonight (September 6) until 5am on Monday, September 9, with diversions in place.
The closure is expected to cause knock-on disruption around the major motorway as up to 7,500 vehicles pass through the junction roundabout at peak times, according to National Highways.

The closure will allow the highways authority to build a new gantry base in order to build a new two-lane loop road to the A12 eastbound towards Brentwood, which will include the construction of new bridges over other roads.
National Highways hopes the major works will increase capacity and reduce congestion, as well as minimising air and noise pollution in the local area by smoothing traffic flow.
It believes the weekend closures are the least disruptive option compared to continuous traffic management over several weeks.
