What's Happening This Winter

Our appointed contractor, Winvic Construction Ltd is making good progress with both the main onsite works and the programme of highways works.

Over the winter months, you will see the following activities on site:

  • Development plateaux – major earthworks will pause during the winter months, but drainage installation and construction of on-site roads will continue. Specific temporary water control systems will be installed to prevent run-off from site.
  • Services – the primary sub-station works have commenced and will continue throughout winter. Ducting and cable works from Riverside will also continue.
  • Rail terminal – earthworks and construction of the mechanically stabilised earth bund (‘Green wall’) will be paused during the winter months, but drainage and ducting works will continue in preparation for the terminal construction programme starting next year.
  • Rail connection - construction of the new rail tunnel linking into the Northampton loop of the West Coast Mainline will continue into the autumn and winter. The tunnel will be covered and landscaped in spring.
  • M1 Junction 15a improvement works – works are continuing both day and night to widen and create the new slip roads.
  • A508 access roundabout and dualling - the new eastbound carriageway will be surfaced and the safety barrier and footway will be constructed during this time. The traffic will switch onto the new carriageway in early 2022.
  • Archaeological, Ecological and Geotechnical investigations and surveys – these have been completed to allow the design works to be finalised, ensuring construction works can commence in Spring 2022.

As part of our earthworks strategy, our aim is to transport as little excavated material from the site as possible as part of our commitment to reducing HGV movements on local roads and to minimise the impact on the environment. The material that we move will help to create ‘bunds’ around the perimeter that will help to screen the development along with the extensive landscaping programme with over 80 acres of parkland and amenity grassland, 18km of footpaths and cycleways, 20km of hedgerows and planting of 60,000 new trees.

Roade Bypass

Roade Bypass is a new 2.5km single carriageway that will be constructed to the west of Roade, tying into the A508 to the north at Northampton Road and A508 to the south at Stratford Road.

The bypass will have 3 roundabouts:

  • A508 Northampton Road
  • Blisworth Road
  • A508 Stratford Road

As part of the bypass construction, a new road bridge across the West Coast Main Line will be built to the north of Bailey Brooks Lane Bridge. Enabling works for the new bypass have commenced following completion of the preliminary investigation works to inform the detailed design of the road and to make sure that all mitigation is completed prior to starting construction in Spring 2022.

The road is scheduled to be completed in the Winter 2023 / Spring 2024. You can find out more about the phasing and timing of the upcoming works here.

  • Geotechnical Investigation Works have been completed around the Rookery Lane and remote junctions.
  • Land Acquisition has been completed and fencing has continued through the period.
  • Archaeological investigations have been completed and reporting works are on-going.
  • Site surveys have commenced.
  • Site clearance to the new railway over bridge have been partially completed and will be completed under railway possession works in January.
  • From January, site clearance to full alignment of the new bypass will commence for completion by March 2022.
  • Meadow translocation was successfully completed in the summer. Hedge translocation will be completed during winter.
  • Construction will start in Spring 2022.

A temporary entrance off the A508 has been created to provide safe access to the area where the site compound is located providing designated parking, electric charging points and welfare for those working on the site. You may see the road sweeper which is employed full time to keep the nearby roads clean following all deliveries to site. A satellite compound will be established in 2022 to facilitate the bypass construction.

Noise and Dust monitoring requirements have been agreed with the local authorities and will be monitored throughout the project. You can read more about how we are planning to minimise disruption and manage our impacts in the Traffic Management section below and in the FAQs.

You can view the timeline of works here and this section of the website will be regularly updated as the status of the works progresses. We will also be providing further updates via regular newsletters and this website.

Traffic Management

The Junction 15 improvement works approved by National Highways will be carried out off-line during the day in preparation for traffic switch in Q1 2022. Current traffic layouts will be maintained until this time, whilst we finish widening slip roads off-line, behind the existing safety barriers. Click here to see the Traffic Management sequence diagrams.

Overnight, lane restrictions continue, to allow safe access to areas in the centre of the M1 Junction 15 and the A45. Lane restrictions will only be permitted between 20:00hrs and 06:00hrs. These restrictions should not cause any delays as traffic flows are lower overnight with all lanes fully open during the daytime.

Traffic Management along the A508 and Blisworth Road will start again in the new year.


There will be some overnight closures of the slip roads during January and February. Click here for details.

The footway across Junction 15 has been closed for the safety of pedestrians during the construction works. The footway will be removed and re-built along the alignment of the new junction. Pedestrians wishing to access Grange Park area from the Collingtree side of the A45 should use Wooldale Road. You can view the Pedestrian Route Alterations here.

We appreciate any work in the public highway can be frustrating and would like to apologise in advance for any disruption – we will be getting through the works as quickly and as safely as possible.

We would like to reassure you that we will work closely with the highways authorities to ensure any disruption is minimised and we will keep you regularly updated of any potential impacts. Highway works have been planned in co-ordination with National Highways and Northamptonshire County Council and will be reviewed on a regular basis during the project.

If road closures are required, diversion routes will be put in place and we will notify you of these in advance. For the latest traffic management information see Traffic & Travel.

We are working closely with the team at National Highways who are constructing a ‘smart motorway’ on the M1 between Junctions 13 to 16, which will convert the hard shoulder into a fourth traffic lane. This is a separate scheme and will be delivered during 2019 through to 2022. Please refer to National Highways for further information.
