M11 Junction 8 Improvements


Approval Status


Fully Approved

Delivery Status


Construction In Progress

Expected Completion Date


Spring 2025

Junction 8 of the M11 is currently operating at capacity and already experiences significant queuing on some arms at peak periods. Stansted Airport is growing at an unprecedented rate of 2 million passengers per annum (mppa) and committed developments in the area, in particular in Bishop’s Stortford, will add to this congestion. Local Plans for East Herts and Uttlesford are being progressed, and this junction is key to these plans being found sound. As part of the discussions around the Uttlesford plan, the issue of M11 J8 was raised. The plan’s success through inquiry will need a clear commitment and delivery of the junction improvement.


The location of the bid is the area around Junction 8 of the M11, including, specifically, the southbound slip from the M11 for traffic accessing the A120, the northbound slip from the M11 for traffic accessing Bishops Stortford / Birchanger Services and the roundabout to the west of the M11 and to the north of the services. The project includes three schemes involving changes to M11 Junction 8 in order to improve traffic flow across the junction, improve access to Stansted Airport, the Services area and between the M11 and the A120.

The Project consists of measures at three locations to improve access to Stansted Airport, the Services area and between the M11 and the A120.  The three locations include:

  • Location 1: South-West of M11 Junction 8
  • Adds an additional inside approach lane from the M11 Junction 8 northbound exit slip onto the A120, with dedicated access into Birchanger Green Services
  • Installs upgraded traffic signals elevated on mast arm gantries
  • Location 2: West of M11 Junction 8
  • Replace the existing A120/A1250 Birchanger roundabout with a staggered signalised junction
  • Widen the A120 eastbound and westbound to three lanes on the approach to the new junction with the A1250, introducing a dedicated lane for A1250 traffic, and a new right turn lane for traffic for Birchanger Lane
  • Realign Birchanger Lane at the new A120 junction within the highway boundary
  • Install toucan crossings (shared pedestrian and cycle crossing) to connect both sides of the A120, with a new footway extending to Birchanger Village and provision of on and off ramps to the on-road cycleway
  • Realign the bus laybys on A1250 Dunmow Road with an uncontrolled pedestrian crossing
  • Create a spur link off Birchanger Lane for direct access to Bishop’s Stortford / A120 (West) for buses / taxis / ambulances
  • Reduce the speed on the A120 to 50mph through the scheme area.
  • Location 3: North-east of M11 Junction 8
  • Add an additional outside approach lane on the M11 Southbound slip road to separate traffic to London Stansted Airport, A120, Takeley, the services, and Bishops Stortford
  • Install upgraded traffic signals that will be elevated on mast arm gantries with overhead signage

The project awarded an additional £1m of LGF funding at the Accountability Board meeting on 12 March 2021. This will help the project to be delivered following cost increases due to Covid-19.
