We can now confirm these new dates for the weekend closures of the M20 to demolish and then rebuild Teapot Lane Footbridge, which crosses the M20 close to Aylesford Station. We need to replace the footbridge deck to increase its height. This is because we are converting the hard shoulder to a running lane and we need to allow space for vehicles travelling on this lane.

The first closure for demolition of the bridge takes place from 10pm Friday September 14 to 6am Monday September 17. The second closure for the installation of the new deck will be the weekend of November 9-12. We have selected these dates in collaboration with the local authorities and emergency services to avoid peak travel dates and events such as the October half term and Bonfire Night.

The local approved diversion route of the A228/M2/A229 is shown here and included on the scheme website. The long-distance diversion route will be signposted on the M25 and elsewhere as the A2/M2.

We will publicise the closures through local media, letters and leaflets as well as signs across the south east motorway network.

All lanes resurfaced with lower noise surfacing: Junction 3 to Junction Lower noise surfacing is being used for lane 1 and lane 4 as part of the M20 J3-5 smart motorway scheme. We have listened to feedback from our customers and have decided to resurface lanes 2 and 3 between junctions 3 and 4 using the same material. We are not resurfacing lanes 2 and 3 between junctions 4 and 5, as this was recently resurfaced and is still in excellent condition.

Some of the additional funding needed to complete this resurfacing will come from one of Highways England’s Designated Funds, which was established to provide environmental and social benefits to nearby communities. This will not affect the planned opening of the smart motorway scheme in spring 2020.
