A421 upgrade

A421 dualling

Latest update

Work starts in September 2018 and is scheduled to be complete by the end of 2020.

Our Executive Committee gave approval to award a contract for dualling the remaining section of the A421 road running from Magna Park in Milton Keynes to the roundabouts in Central Bedfordshire adjacent to junction 13 of the M1. The majority of this stretch falls in Central Bedfordshire.

About the project

We're working with Milton Keynes Council (link opens in new window) to deliver the improved section of the A421 and will now be leading on the project. Both councils will each contribute up to £3 million towards this £28.5 million project.

The new road layout will improve east-west transport links by widening this last remaining 3km section of the A421 and this stretch is used by almost 30,000 vehicles per day.
