The work on the M25 junction 30 will start in early November and mean that the scheme, to increase capacity and reduce congestion, will now finish in summer 2016, earlier than the original planned finish of autum 2016.
Highways England project manager Lizzie Pauling said:
The improvements to the A13 and M25 junction 30 will provide drivers with safer and more reliable journeys on these already heavily congested routes. Since construction started earlier this year, we have identified an opportunity to start on the M25 earlier and finish the work in summer 2016, earlier than originally planned.
Narrow lanes and a temporary 50mph speed limit will be place on the M25 and a temporary 40mph speed limit on the roundabout itself, from Monday 2 November.
The work has been carefully planned to minimise disruption, including traffic modelling to ensure that shoppers over the Christmas period can continue to the Lakeside Shopping area.
The scheme will support economic growth in the region such as the Thames Gateway and provide drivers with safer and more reliable journeys into and out of Essex.
