To improve the design of the proposed Lower Thames Crossing, and help us plan how we build it, we are currently undertaking a series of works at locations throughout North Kent and Essex. These works are to help us refine our plans for our application for the Development Consent Order. (Read more about our survey works in our leaflet.)
Our current phase of survey works will continue until Autumn 2021.
We are continuing with the following works:
Cable percussion boreholes is the most common technique that we’re using. This involves a 7m tall frame lowering drilling tools up to 60m deep. These survey works are mainly on private farm land along or near to the proposed route.
We are digging shallow trenches with mechanical excavators to assess the archaeological features of a site. The trenches are approximately 30 metres long and 2 metres wide. These survey works are mainly on private farm land along or near to the proposed route.
We are digging small trenches either by hand-digging or with the use of a vacuum excavator, before scanning for existing below-ground utilities. Some survey locations include public roads which may require either a full road closure or lane closure with temporary traffic lights.
We have installed a number of small survey nails along and near to the proposed route, this includes on private land and public pathways or roads.
These survey nails enable us to identify the geographic coordinates of the proposed route and associated works. This is helps us with our designs which in turn also helps us to better plan how we would build the project.
It is possible that you may notice our staff visit survey nail locations for short periods on occasions.
The survey nails will be a series of points where we measure the Easting, Northings and Height at each location using a Global Navigation Satellite System (GNSS). We will then calculate the distance and angles between them.
This allows us to create a grid of known coordinates, which would allow us to position the proposed route with accuracy and help us with our designs and plans to build the project.

Information for land and property owners
Highways England have produced a series of booklets to provide assistance to land and property owners located near the proposed Lower Thames Crossing.
Legacy and benefits
We are working with our stakeholders to identify opportunities to help local communities. The design will deliver enormous benefits, but we want to do more. We want to leave a lasting legacy for both residents and visitors. That could mean new walking, cycling and horse riding networks, creating apprenticeships and jobs as well as identifying volunteering opportunities.
We have already started working with local stakeholders, organisations and groups to identify the best areas to concentrate on.
We will be publishing more information on our approach to maximising the benefits of the scheme in the future, sign up for alerts.
The Lower Thames Crossing would provide a number of benefits to local communities and the environment. It would reduce congestion at the Dartford Crossing, support economic growth locally, regionally and nationally, and provide additional capacity and more reliable journeys across the River Thames. Other benefits include:
- 80% of the new road would now be in a cutting, false cutting or tunnel to reduce its visual impact.
- Two new public parks would be created:
– Chalk Park, a 38-hectare park near Gravesend
– Tilbury Fields, a 48-hectare park overlooking the Thames in Thurrock.
- We would remove the need for over 470,000 HGV movements on local roads by beneficially reusing excavated material in the parks.
- We are replanting over 260 hectares of new woodland – six times more trees than the number lost. In addition, we’re creating a new 100-hectare community woodland in partnership with Forestry England, near Great Warley in Brentwood.
- There would be 46km of new, realigned or improved footpaths, cycleways and bridleways.
- Seven new green bridges would connect footpaths, bridleways and ecological habitats.
- New and improved habitats for wildlife would include 120% more hedgerows, 40% more ponds and 10% more ditches.
- Reduced congestion at the Dartford Crossing and approach roads would improve local air quality.
We continue to engage with a broad range of businesses across Essex and Kent, including ports, freight companies and retail organisations, as well as business representative groups, through which we can reach their member networks of thousands of businesses across the region.
We work to build relationships with these businesses and organisations, by updating them every step of the way on the development of the project, and hearing their views about how the Lower Thames Crossing will enable their businesses to grow.
