Section 56 Planning Act 2008
Regulation 9 of The Infrastructure Planning (Applications: Prescribed Forms and Procedure) Regulations 2009
Notice of Acceptance of an Application for a Development Consent Order
A122 Lower Thames Crossing

Notice is hereby given that the Secretary of State has accepted an application by National Highways Limited of Bridge House, 1 Walnut Tree Close, Guildford, GU1 4LZ (“the Applicant”) for a Development Consent Order (“DCO”) under the Planning Act 2008 (“the Application”). The Application was submitted by National Highways to the Secretary of State c/o the Planning Inspectorate (“the Inspectorate”) on 31 October 2022 and was accepted for examination on 28 November 2022. The reference number applied to the Application by the Inspectorate is TR010032.

Summary of the Project

The DCO would authorise the A122 Lower Thames Crossing (the “Project”), located within ten administrative areas: Brentwood Borough Council, Dartford Borough Council, Essex County Council, Gravesham Borough Council, Kent County Council, London Borough of Havering, Maidstone Borough Council, Medway Council, Thurrock Council and Tonbridge and Malling Borough Council. The Project would provide a new road connection between the A2 and M2 in Kent, east of Gravesend, crossing under the River Thames through two bored tunnels, before joining the M25 south of junction 29, as set out in the plans which accompany the Application. The Project in summary involves:

  • A new road, the A122, approximately 23km long connecting to the existing road network from the A2/M2 to the M25.
    • 4.25km of the new road would be in two tunnels, one southbound and one northbound.
    • The new road would have three lanes in both directions, except for link roads, stretches of the carriageway through junctions and the southbound carriageway from the M25 to the junction with the A13/A1089, which would be two lanes.
    • a maximum speed limit of 70mph would apply to the new road.
    • The new road would be an all-purpose trunk road, with additional vehicle restrictions imposed and managed through signage so that walkers, cyclists, horse-riders and slow-moving vehicles would be prohibited.
    • Junctions are proposed at the following locations: the A2 to the south-east of Gravesend; the A13/A1089 in Thurrock; and the M25 between junctions 29 and 30.
  • Modifications will be made to a number of local roads to accommodate the new road, and modifications to the A2, the A13 and the M25 to connect with the A122. There would also be adjustments to a number of public rights of way, used by walkers, cyclists, and horse riders.
  • New structures will be constructed, and changes made to existing ones (including bridges, buildings, tunnel entrances and viaducts) along the length of the new road and the modified roads.
  • Construction of the Project would also require the diversion of a number of utilities, including gas pipelines, overhead and underground electricity cables, as well as water supplies and telecommunications assets.

The DCO would authorise the compulsory acquisition of land, interests in land and rights over land, and the powers to use land permanently and temporarily for the construction, operation, and maintenance of the Project.

The DCO also includes provision for a number of ancillary matters, such as road user charging, the diversion and stopping up of lengths of existing highways and private means of access in the vicinity of the Project route, the classification of highways including trunking and the application of speed limits, the provision of byelaws applying to the tunnel and tunnel approaches, as well as the application, disapplication and modification of legislation relating to the Project.
