All roads have now reopened on the newly constructed bridge deck at Agar Grove in Camden, north London, a key milestone in the £30 million project to modernise the 160-year-old railway structure.

The Agar Grove bridge, which spans the Midland Main Line, was fully replaced over a nine-day period in December 2024 in a tightly coordinated operation designed to enhance rail services and road infrastructure in the area. Train services resumed on schedule on 30 December following the successful installation of new beams, parapets, and deck components. Overhead line equipment and railway tracks were also reinstated during the short window of rail closure.

After the railway reopened, teams moved quickly to dismantle the crane and reinstate vital utility services. A single lane of road traffic was reintroduced in February, with the temporary footbridge removed in March. Final resurfacing of the bridge deck was completed over the weekend, allowing the entire area to reopen to road traffic from Monday 12 May.

The major bridge replacement began after the last train on 20 December 2024. Within just days, the old structure was demolished and the new deck put in place. In addition to the primary bridge works, Network Rail teams took advantage of the track closure to complete over 50 secondary tasks — including vegetation clearance, track maintenance, and power cable upgrades.

A new pedestrian route linking St Augustine’s Road across the bridge is due to open later this week, with all remaining footpath work expected to be completed by mid-June, officially bringing the transformative infrastructure project to a close.
