The route

The fly through shows the design of the Lower Thames Crossing at the time of the statutory consultation. This design is subject to change following the consultation.

The Lower Thames Crossing route has been divided into three sections:

  • South of the river in Kent – M2/A2 junction
  • The crossing
  • North of the river in Thurrock and Essex – Tilbury junction, A13 junction, LTC/M25 junction, M25 junction 29

What’s happening now?

In early April 2019 we will be setting up and securing the Marling Cross site compound opposite Nell’s Café. The compound is part of our work to develop plans for the Lower Thames Crossing by studying the ground conditions in the area.

Fences will start going up from early April, and we expect to complete the fencing by the end of April. After the fencing is set up we will ensure suitable security measures are in place such as CCTV and/or 24/7 security. We anticipate the site being fully operational in the summer when it will be used for storing equipment, temporary offices, welfare facilities and parking for staff. For more information click here.

The Lower Thames Crossing 2018 consultation closed at 23.59 on Thursday 20 December. All the consultation information and documentation remains on this website for your reference, but we are unable to accept any new consultation responses.

All of the issues raised during consultation will be taken into consideration as we continue develop the scheme.

If you would like to be added to our email list to be kept up to date with the project’s progress please send a request to If you responded to the consultation and have already provided an email address, we will contact you automatically with updates.

We will produce a report that explains if, and how, we have changed the proposals in response to feedback provided from the consultation. This feedback will form part of our Development Consent Order (DCO) application, which would give us the planning consent we need to start construction.

If we are awarded a DCO, it is unlikely that our design will change significantly during construction. Therefore, it is important that everyone gives us their views at this stage.

Design changes

Road height – we have lowered the height of the road in some locations by as much as 5-6 metres to reduce its visual impact. This change was made following feedback from the 2016 consultation.

Number of lanes – the route will be a motorway with three lanes in each direction, along the whole route from the M25 to the A2.

It will have no hard shoulders in common with smart motorways.

This will provide enough capacity for peak hours and to meet future demand. It will reduce journey times across the Thames and increase capacity for road users across the river by more than 90% east of London.



What areas are affected

We are already talking with landowners and occupiers affected by the Lower Thames Crossing and we will continue to work closely with them. We understand that if you live in the area, you will have concerns about how the project may affect you – and we will provide all the help and support we can.

While significant areas of land are required for the scheme, we are seeking to reduce the impact on landowners. We are talking to landowners at every stage to understand their specific concerns.

We have set out a development boundary, pictured opposite, that outlines the extent of the land we may need. Since the preferred route was announced in April 2017, we have contacted people whose land or property we believe is within the boundary. Our dedicated team is working with them to explain the proposals and rights they may have.

Within this boundary, some of the land along the route of the new road will be needed permanently and other areas, such as construction sites or land needed to divert utilities including power lines or gas pipes, may only be needed temporarily.

The updated development boundary is shown here; Large scale land use

You can also find a development boundary comparison plan which shows the changes that have been made to the boundary since it was last published in July 2018.

When work is complete, any land that is not needed permanently or for environmental purposes will be returned to its previous use wherever possible.
