Have your say on the proposals for the Lower Thames Crossing - Supplementary Consultation - deadline 2 April 2020

2020 Supplementary Consultation - Revised DesignIn January 2020, Highways England launched a supplementary 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.  For more background information, see Lower Thames Crossing.

The latest consultation focuses on changes proposed in response to feedback from the statutory consulation held in 2018, ground investigation works and other discussions with statutory authorities and public agencies either side of the river.

The main changes include:

  • Moving the southern portal of the tunnels 350 metres south to reduce impact on the Thames and Estuary Marshes Ramsar site
  • Revisions to the junction with the A2 and a new link road from Valley Drive in Gravesend to retain connection with the A2/M2
  • Revised development boundary (subject to ongoing refinement) to cover land required for utility diversions and construction compounds
  • Removal of the Rest and Service Area and Tilbury junction on the north side of the river
  • Redesign of the slip roads and other adjustments to the A13 and A1089 junction
  • Removing one lane on the southbound route between the M25 and A13/1089 junction.
  • Changes to the structures on the route through the Mardyke Valley
  • Changes to the M25 junction and to M25 Junction 29 to avoid the need for demolition of structures or diversion of utilities.

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 revised 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.  We 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.

On 20 March Highways England announced that they were extending the deadline for consultation responses to 2 April.  For information about the proposals and how to respond, click here.  

TGKP will be responding and we will publish our response in due course.



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:

  • Two 2.6-mile (4km) tunnels
  • Approximately 14.3 miles (23km) of new road connecting the tunnel to the existing road network
  • 3 lanes in both directions (except southbound between M25 and A13/1089) 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
