Firms have until middle of next month to register interest in mammoth schemes
Highways England has started the race for two deals worth £1.9bn for approach roads to the new Lower Thames Crossing.
The design and build contract for roads on the Kent side of the river is worth £600m, with those for the Essex side valued at £1.3bn.
The contract for the Kent side of the tunnel includes connecting the A2/M2 corridor via a multi-level junction close to the tunnel’s southern portal. Other work includes widening the existing A2 and a redesigned Gravesend East junction.
Work on the Essex side will involve building a stretch road north of the tunnel’s northern portal and continuing for 12.7km to a junction with the M25.
Highways England is looking to shortlist up to four firms or joint ventures for each lot.
Firms have until 14 May to register their interest in the project.
