Euston approaches

The Euston Approaches is the section of track that will connect the Euston Tunnel South Portal to Euston Station.  It also encompasses the part of the Euston Tunnel that runs south of the A4201 Parkway Road.

The map below shows an overview of the HS2 route in the London Borough of Camden. A number of HS2 construction compounds have been set up between Euston Station and Adelaide Road.

Our Three month construction look ahead, Summer 2021 provides details of planned construction activity in the Camden area.

Euston Cavern headhouse

The Euston Cavern Headhouse, which will provide emergency access to the high-speed railway, is one of eight headhouses that will be built in Greater London above shafts leading down to the 26 mile-long London tunnels below.

The section of HS2 tunnel between Euston Station and Old Oak Common Station is known as the Euston Tunnel. The Euston Cavern headhouse will be located in the railway cutting at the northern end of Park Village East.

The cavern headhouse will be three-storeys with one storey visible above street level and two below. Final design is now complete and incorporates feedback received since 2018.

View the Euston Cavern Headhouse information slides from our events in March 2021, for full details of the final designs and design engagement journey.

Euston tunnel ventilation shaft head houses

Head houses provide access to the tunnels for maintenance and emergency services when needed, evacuation, electrical high voltage power supply for shaft and tunnel equipment and ventilation needs.

As part of the development of the scheme during the parliamentary process a ventilation shaft was introduced at Canterbury Works and the HS1-HS2 link was removed from the scheme. This created the opportunity to review and reassess the tunnel ventilation and emergency access needs for the Euston Tunnel, which carry HS2 trains between Old Oak Common and Euston, surfacing at the Euston Tunnel portal just south of Mornington Street.

In July 2018, information on the layout of the rail approaches and the tunnel entrances to the north of the station was shared and we sought your feedback on the proposals for the above ground structures in the approaches and at Adelaide Road.

Information about the questions asked and the feedback received from the engagement is available here.

The information on the design in the Euston approaches is available to view here.

Vehicle Holding Area

The Vehicle Holding Area (VHA) is a parking facility built within the London Zoo car park. The main purpose of the VHA is to hold HS2 construction lorries in a safe location until a nearby worksites are ready to receive deliveries. This helps to avoid lorries queueing into streets near worksites, up to 25 vehicles can wait here. We aim for as many vehicles as possible to travel directly to and from worksites without needing to visit the vehicle holding area.

  • The site due to become fully operational from August 2021 until December 2033.
  • Working hours: Monday – Friday, 8am to 6pm, Saturdays, 8am to 1pm.

Wildlife support:

  • 500m of hedgehog habitat planted in Regent’s Park in spring
  • Mammal tunnel – Europe’s largest – beneath site entrance for safe hedgehog crossing
  • Wildlife cameras in tunnel to capture hedgehog activity

Lorry routes for SCS main works construction

SCS have been developing their plans for the lorry routes that will be used for the main civil engineering construction works from Hampstead Road Bridge northwards.

The proposals are developed based on the routes described within the Environmental Statement, the most suitable routes to work sites, feedback from discussions with the community and local authority, the shortest route to the Transport For London Road Network and with a view to reducing the impact on the community and environment where possible.

In 2019 we carried out engagement on these proposals and the presentation shared at the events is available here.

The schedule 17 application for the lorry routes was been approved by Camden Council in August 2020.
