Upper Holloway Bridge

Temporary closure of the A1

We will close the A1 Holloway Road between Fairbridge Road and Wedmore Gardens in separate phases until Monday 16 January 2017. A diversion route will be clearly signed at all times.

Businesses along the Holloway Road are open as usual during the closures.

Find out how the closure could affect your journey on the Upper Holloway Bridge travel advice page.

Why we are doing the work

The bridge has reached the end of its operational life and is beyond simple repair. Not replacing the bridge would mean restricting the weight of vehicles that use the bridge and closing lanes to carry out maintenance, disrupting traffic and rail operations in the long term.

We are investing around £25m to rebuild the Upper Holloway Bridge. This is part of our programme to improve London's roads and public spaces.

We will replace the bridge deck which sits beneath the road and strengthen abutments that support the bridge from below.


The new structure replacing the existing bridge will have an expected lifespan of 120 years.

Utility pipes and cables (carrying gas, electricity, water and telecommunications) in the existing carriageway will be relocated to a new service bridge. This will reduce the need to close traffic lanes on the road bridge during future maintenance of utility pipes or cables.

Key phases of the work

The project is divided into three key phases:

  • Service bridge installation: The service bridge will carry the utility pipes and cables currently buried in the carriageway of the existing bridge
  • Current works: diversion of the utility pipes and cables to the service bridge (until December 2016)
  • Highway bridge deck demolition and replacement: planned for the Christmas 2016/2017 period

Current works

Our contractor Hochtief (UK) installed the new service bridge in June 2016 during a full closure of the A1 Holloway Road at Upper Holloway station.

We are now moving the pipes and cables (carrying gas, water, electricity and telecommunications) from the existing bridge to the new service bridge.

During this move, we discovered the utility services in and around the Upper Holloway Bridge are unexpectedly complex. We also found difficult ground conditions and a leaking water main. This means we need to do more work than we had originally planned. This has delayed the project.

During the closure

To minimise the impact of traffic on the diversion route while Holloway Road is closed between Fairbridge Road and Wedmore Gardens:

  • HGVs are banned from using Tufnell Park Road
  • A HGV diversion route is signed
  • CCTV cameras to help monitor traffic conditions and enforce the HGV ban
  • Significant changes to bus services in the area
  • Upgraded traffic signals

Next steps

To ensure that we can demolish the bridge as planned at Christmas/New Year, we now need to put a series of road closures in place so the utility infrastructure can be safely moved.

This work must be finished now so the electrification of the Gospel Oak to Barking line can go ahead on schedule, improving rail services and doubling capacity on this route.

We apologise to the London Borough of Islington, residents and businesses for the extra disruption these road closures will cause. We will do absolutely everything we can to complete the work as quickly as possible.

We are re-planning all other non-emergency road works in the area and are communicating regularly with our customers and partners.

Changes to travel

Pedestrian diversions

Pedestrians at Upper Holloway can now use the western footpath. The eastern footpath is closed while we continue to divert utility pipes and cables.

Temporary advisory speed limit

For the safety of pedestrians and cyclists, a temporary 20mph speed limit has been introduced between Hampden Road and St John's Villas on the A1 Holloway Road. This will remain in place until the works finish in 2017.

Parking and loading bays

Some parking bays in Rupert Road and Hampden Road have been suspended to provide space for storage and worker facilities. The site office compound will remain in Hampden Road and Rupert Road until the works are completed.

Loading bays outside 589, 672 and 692 Holloway Road and opposite 678 Holloway Road have been suspended until 28 February 2017.

Bus routes

Bus routes 4, 17, 43, 134, 263, 271, 390, N20 and N41 will be affected. The nearest alternative bus stops will be clearly signed. Check the latest bus status updates.

We will ensure works at the station take place when train services are not running where possible.

From December 2016 there will be changes to bus services in the area as part of the Archway gyratory scheme.

Upper Holloway station closure

Upper Holloway station is closed until February 2017 while works are completed to electrify the Gospel Oak to Barking line. The electrification works are being completed by Network Rail.

We will run a replacement bus service. See London Overground closure travel advice.

Minimising noise and disruption

We will be working 24 hours a day, seven days a week. Noisy works will take place from 08:00-20:00. This has been jointly coordinated with London Borough of Islington's environmental team.

We will continue to monitor noise levels and make every effort to minimise it.

We are using a range of measures to reduce noise, vibration and disruption including:

  • Noise-reducing acoustic barriers used wherever possible
  • Compressors and generators fitted with acoustic covers to reduce noise
  • Vehicles, plant and equipment fitted with exhaust silencers
  • Turning off plant and equipment when not in use
  • Dust levels monitored on a daily basis
  • Water sprays used to reduce airborne dust
  • We ensure lights do not shine into people's homes

Our partners

This project is being delivered in partnership with Hochtief (UK) Construction, and Ramboll and Parsons Brinckerhoff.
