An update has been published by developer Segro as significant roadworks continue for its Rail Freight Interchange.
Commencing on March 23, Park Street Roundabout has been targeted for a series of "improvement works".
According to Segro, a complex traffic management system will be installed over three night -being March, 23, 24 and 25. These will remain in place for the majority of time during the roundabout works.
In order to carry out this work the Park Street Roundabout will be closed between 8pm - 6am on each of the three nights, with diversion routes in place and appropriate signage on the network. Arrangements will be in place for emergency vehicles.
Nearby, 65 weeks of works are under way, affecting the A414 North Orbital Road and London Colney Roundabout.
The developer said there has been a "significant amount of planning undertaken for this project" to minimise disruptions for road users and residents.
"The works require a complete overhaul and remodelling of the Highway assets which can only be delivered with extensive peak, off‑peak and night time traffic management," a statement published by Herts Connected reads.
Scope of Works
The main activities include:
- Installation of new deep drainage systems, including chambers, gullies, filter drains, and a large attenuation tank.
- Utility ducting and diversions (Openreach, Cadent, UKPN and BPA).
- Carriageway widening with new foundations, kerbs, and full tarmac construction.
- Resurfacing works, including high‑friction surfacing and new road markings.
- Installation of new traffic signals, detection loops, and associated cabling.
- Footway upgrades including grassed areas, concrete paving, and tactile paving.
- New permanent bollards and galvanised street lighting.
Segro expressed its gratitude for the community's co-operation during these works.
