A21 in the Motorway Database

Published on 15 July 2017

This week, a brand new flyover at Longfield Road, just east of Tunbridge Wells in Kent, was opened to traffic for the first time. It replaces a roundabout on the A21 and means that the long-awaited Castle Hill to Pembury Improvement scheme is nearly finished.

When the cones are all cleared away, the A21 will have a continuous expressway from the M25 to the Kippings Cross Roundabout south-east of Pembury, a distance of 15 miles - and now that its run is no longer interrupted by a congested and frustrating gap south of Tonbridge, it's about time it was added to the Motorway Database.

So today there's a brand new entry for the A21 in the Motorway Database, complete with construction timeline and strip map of the whole route - including that brand new flyover.

"Long Awaited" is an understatement! When the MoT held its consultations on the proposed Pembury bypass in the late 80's, we all said "Why haven't you included the Castle Hill improvement?" Our predictions were proved right, with massive queues morning and evening at the end of the Tonbridge or Pembury bypasses, caused by the Longfield roundabout. I used to commute up and down the A21 from 1986 till 2009 so the delays at this point became engraved on my soul....

Imperfectly Odd: Batheaston Bypass

It has viaducts, a tunnel and plenty of controversy, but the amazing Batheaston Bypass doesn’t really work. What went wrong?

South London's lost motorways

Completing the story of London's epic Ringways, we've just published the Southern Radials, five more motorways that never saw the light of day.

To the north east!

West Cross Route

Desperately-needed but never built, this was one of the only London urban motorway plans that were ever progressed to the construction stage.
