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 section of the A421 and this stretch is used by almost 30,000 vehicles per day.
