Project information

A12 junction 27 slip roads concrete surface repairs and maintenance - February 2021

From Wednesday 17 February 2021, we will be repairing the concrete surface on the A12 at junction 27 Spring Lane. We’ll be doing repairs and maintenance of the concrete road surface on the slip roads at junction 27 in both directions.

The work will take around four weeks, and we’ll also be clearing drains, repainting road markings, and inserting new reflective road studs (cat’s eyes). At the same time we will be resurfacing the A12 southbound carriageway between junction 27 and 26.

For safety and to minimise disruption to motorists, we will need to close the road to do our repairs. There will be diversions in place using junction 26 (Eight Ash Green) and the A1124 and A133 Cymbelline Way to Spring Lane Roundabout.

Road closures

Eastbound and westbound exit slip roads, junction 27
We will need to fully close the road on the following dates:

  • 8pm on Friday 19 February until 6am Monday 22 February inclusive
  • 8pm on Friday 26 February until 6am Monday 1 March inclusive
  • 8pm on Friday 5 March until 6am on Monday 8 March inclusive

There will also be daily overnight road closures from 8pm to 6am from Monday 22 February until Friday 5 March inclusive.


Eastbound exit slip road closures, traffic should exit at junction 26, onto the A1124, then follow London Road and join the A133 Cymbelline Way.

Westbound entry slip road closures, traffic should follow the A113 Cymbelline Way, onto London Road, then follow the A1124 and join the A12 at junction 26.

During November and December 2020, we have been resurfacing and repairing potholes and cracks in the concrete road surface on the A12 main carriageway between junction 22 and junction 24 in both the northbound and southbound directions. You can read about the work we did in our two newsletters:

We changed our initial approach to take advantage of the reduced traffic as a result of Covid 19 lockdown restrictions. We were able to complete the work earlier to avoid disruption in December, supporting people with Christmas shopping and other journeys, and to help fuel the economy.
