What we're doing this spring

Since starting the project, we have reviewed 10 years-worth of safety data for the A21. This has helped us refine our proposals so there’s a tangible safety benefit for road users.

We’re looking at where best to put signs and we’re analysing how different road markings could increase safety. Our work on signs includes signs for junctions, schools, villages and hazards.

We’ve also started a review of speed limits along the route to see if those currently in place match the characteristic of the road and if they are encouraging positive driver behaviours.

Details of specific sites and interventions that are under consideration in our preliminary design stage on the A21 can be found in these documents:

Link 1 – M25 to Tonbridge

Project information

The A21 has, for many years, suffered from a significant level of collisions.

We are bringing forward a series of schemes to improve safety along this corridor, which will include, amongst others:

junction improvements
improvements to road alignment and visibility
changes to speed limits
improved signing, markings and road studs

This work is to improve safety and won't improve capacity along the A21. We'll be looking at that as part of our 'route strategy' work which is due to start shortly.
