Have your say on the proposals for the Lower Thames Crossing - Consultation Closed

In autumn 2018, Highways England launched a ten-week consultation on the Lower Thames Crossing – a major new road which would nearly double road capacity across the river Thames and almost halve northbound journey times at Dartford Crossing.

The 14.5 mile route connecting Gravesham, Kent and Thurrock, Essex would be a three lane motorway connecting the M2 near Rochester and the M25 in Essex between North and South Ockendon. It would include a 2.4 mile-long tunnel under the Thames between the east of Gravesend and Tilbury – the longest road tunnel in the UK – and, at over 50 feet wide, the third largest bored tunnel in the world.

Commenting on the positive impact the new Crossing could have for businesses and residents in North Kent, TGKP's Chief Executive Matthew Norwell said:

“The Lower Thames Crossing is perhaps the most important highways infrastructure investment affecting Kent and Essex, but its significance goes far wider than that. We desperately need relief from the congestion at the Dartford Crossing, with all the negative impact that has on economic productivity and on the health and wellbeing of local residents. We welcome this consultation on the detail of the proposed scheme.  We want to make sure that Highways England get the design right, not just on the Crossing itself but also on the local connections and other network improvements that are needed in Kent and Essex to ensure the whole system works smoothly and delivers net benefits to North Kent. 

“I would encourage businesses and residents alike to look at the plans and respond to the consultation on this once in a generation project so that the final scheme is as good as it can be and addresses any concerns people may have.”

Launching the consultation on 10 October, Tim Jones, Project Director for Lower Thames Crossing, said:

“For too long the Dartford Crossing has been the only way to get across the Thames east of London. It is a vital gateway, but carries more traffic than it was ever designed for and drivers there suffer from regular delays, severing communities and holding back economic growth.

“The Lower Thames Crossing is the most ambitious project of its kind ever in the UK and the biggest single road upgrade since the M25 was completed more than 30 years ago. It would almost double road capacity across the Thames to cut congestion, end the daily delays at the Dartford Crossing and boost the resilience of the whole road network. This consultation is an important opportunity for people to share their views on our proposals and help shape the Lower Thames Crossing.”

On the south side of the Thames, the new road will link the tunnel to the A2 and M2 in Kent. On the north side of the river, it will link to the A13 in Thurrock and then junction 29 of the M25 in the London Borough of Havering.

The Lower Thames Crossing will comprise:

  • A 2.4-mile (4km) tunnel
  • Approximately 14.5 miles (23km) of new road connecting the tunnel to the existing road network
  • 3 lanes in both directions with a maximum speed limit of 70mph
  • New structures (including bridges, viaducts and an underpass) along the length of the new road
  • Improvements to the M25, A2 and A13, where the Lower Thames Crossing connects to them

The consultation ran for 10 weeks, closing on 20 December 2018. Highways England are now analysing responses to the consultation to inform decisions about next steps.  For information on the LTC consultation visit:
