A13 North Stifford junction improvement
Improving the A1012 North Stifford junction to reduce queuing traffic, improve operation and road user safety.
The A13 is a major road which provides vital transport links between Central London and south Essex. The A1012 North Stifford junction provides an important link to Stifford and the town of Grays, the largest town in the borough and unitary authority of Thurrock, Essex.
The junction, which links directly with Grays, was highlighted as one of the locations marked for improvements as part of our Junction Improvement Programme; a package of works aimed to better the operating and performance of eight individual junctions around the M25 and its linking roads. Most of the funds for the programme came from the Department for Transport congestion relief fund.
The layout of the North Stifford junction had a poor angle to the carriageway, meaning road users approaching the roundabout from either slip road found it difficult to check for oncoming traffic. The single-lane eastbound and westbound exit slip roads were also wide but lacked any lane markings, which could be confusing for drivers.
Our teams started preparation work in summer 2021. By carrying out these activities in advance, such as diverting existing utility services and clearing vegetation ahead of construction, we minimise the risk of any delays to the main works and increase efficiency.
We removed a small area of vegetation to enable the widening of the slip roads; however, this was minimal and confined to the area alongside the slip roads. Any vegetation that needed to be removed to facilitate the widening work will be offset by a project to replant an equivalent amount of vegetation nearby. This will follow the completion of the construction works around the junction.
To create safer and more reliable journeys around the junction, we will be:
- Widening the current single-lane eastbound and westbound exit slip roads to create an additional lane, to increase capacity and improve journey times
- Installing new street lighting, road markings and signs to reflect the new road layout
- Working with Thurrock Council, who will be installing new traffic lights to improve safety at the junction
