Motorists have been warned to plan ahead with a four-night closure near a busy Hertfordshire roundabout set to begin this evening (September 1).

The A414 will be shut overnight eastbound between the M1 and Park Street Roundabout as part of the controversial Segro Radlett freight development.

The closure runs until Saturday morning (September 5). While the exact hours do not appear to have been listed online, overnight closures tend to be between 8pm and 6am.

An update from Segro's community liaison team reads: "Diversion routes will be in place supported by appropriate signage across the network.

"We would like to thank you for your cooperation during these works and we will continue to provide updates as the works progress."

Hertfordshire County Council has advised anyone needing to use the route to allow extra time for their journeys.

This week will bring some good news for motorists as a daytime closure at the A5183 Watling Street North exit is expected to be removed tomorrow morning (September 2). It has been closed 24/7 since the end of July as part of works on the freight project.

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".
