The £600m Kent Roads contract is a two-stage design and build contract for the part of the route from the A2/M2 corridor to 1km south of the southern tunnel entrance, with strategic utilities and environmental interfaces

The £1.3 billion Roads North of the Thames contract, is also a two-stage design and build contract delivering the route from 1km north of the northern tunnel entrance to Junction 29 of the M25. New link roads are required to connect the route with the M25, A13 and A1089

The shortlist for the £2bn tunnel contract connecting the two roads was revealed earlier this year.

The successful bidders will design and build a total of 14.3 miles of new roads that will connect the longest road tunnel in the UK to the strategic road network.

Matt Palmer, Lower Thames Crossing Executive Director, said “The Lower Thames Crossing is the most ambitious road project this country has seen since the M25 was completed 35 years ago.

“These contracts show our commitment to this project, which will support 22,000 jobs during its construction and provide a huge economic boost to the UK economy when it opens for traffic.

“Our challenge is to build a new crossing that not only supports the next generation of low carbon vehicles but also allows us to enhance the natural environment and leave a positive legacy for generations to come.

“We look forward to this next stage of the procurement process with the five shortlisted companies and hope the final bids match our aspirations.”
