Motorists have been warned to plan ahead as overnight closures begin at a busy Hertfordshire roundabout this evening, October 5.

The north side of the Park Street Roundabout will close from 8pm to 6am each night until Friday (October 9)

The works will close the A414 from the M1 to Park Street Roundabout eastbound, the A414 eastbound from Park Street Roundabout to the A414 slip road to Napsbury Lane and the A5183 Watling Street North.

A Hertfordshire County Council spokesperson said: "Diversion routes will be signed and clearly marked. Please plan ahead and allow extra time for your journey. Thank you for your patience."

Similar works took place on the south side of the roundabout last month.

The earlier work was part of Segro’s controversial rail freight project, but this closure is for county council works.

Segro controversially purchased 419 hectares of land at the location of the former Radlett Aerodrome in 2023 and has seen off opposition from campaigners that resulted in a failed High Court appeal.

Developers intend to build a freight terminal on the land, which opponents say will bring thousands of extra lorries and vans onto the already congested roads.

However, Segro's chief executive officer David Sleath has said it will "benefit the national and local economies".
