The A2 will remain as four lanes in both directions with hard shoulders throughout. The M2 will be widened from three lanes to four in both directions through junction 1.
Two one-way link roads will be provided north and south of the A2, connecting to the existing A289 and the old A2 at the eastern end. Neither of these link roads will connect to the A2 at M2 junction 1, with these connections being made at the site of the new LTC junction instead.
The A2 will be kept at its existing height and the link roads will be at approximately the same height.
We will need to rebuild a section of the M2/A2 immediately to the west of the new junction and for approximately 2 miles (3.5km) to the east, including junction 1 of the M2.
The route will pass under Thong Lane and approach a new junction with the A2, situated at the eastern edge of Gravesend. The road will be in a cutting approaching the tunnel.
The following maps show the proposals for the section south of the river in Kent.
