THE next stage of an Â£80 million scheme to relieve congestion around junction 30 of the M25 and the A13 corridor near Thurrock in Essex starts next week.
Lanes on the slip roads and the junction rounadabout will be reduced to a single lane overnight, between 10pm and 5.30am, from Tuesday January 26 for approximately 10 nights.
These restrictions will be in place to keep drivers and road workers safe while they are carrying out improvement works, and also to reduce conflict from merging traffic.
The work involved in this stage of the scheme includes:
Installation and renewal of traffic signals
Road markings, road signs
Sheet piling to enable widening works
Once installed the temporary traffic management on the M25 junction 30 gyratory and associated slip roads will include:
A temporary 50mph speed restriction, enforced by average speed cameras, will be put in place to maintain the safety of road workers and travelling public
Hard shoulder running
Slip road and carriageways closures
The work is part of a major project to increase capacity at this busy junction and help unlock the multi-billion pound regeneration of the Lower Thames Valley.
The A13 through the junction is being widened from three lanes to four in each direction, and the junction itself is being upgraded by adding segregated left turns to and from the M25, and improvements to the other slip roads.
Safety barriers, drainage and lighting are also being upgraded and it is estimated that the project will help to reduce accidents by 18%. The work is scheduled to be completed by summer 2016.
In October, Highways England announced that work on the upgrade would be completed earlier than planned bringing it from autumn next year to the summer
Work on the M25 started in October, and work on the A13 has been underway since March 2015.
