Islip Bridge traffic signal installation and improvement work
The project will repair the bridge and put in place improvements for pedestrians.
In June 2026 we will carry out traffic signal installation and improvement work at Islip Bridge to keep it safe, improve pedestrian access and reduce unsuitable through‑traffic in the village.
This page provides more information about this work and will be updated with any changes to the programme.
Why the work is needed
- Increasing traffic volumes and heavier vehicles have led to deterioration of the bridge.
- Action is required to protect the bridge and ensure safe use for all users.
- Feasibility studies have confirmed the most effective and best‑value solution is to direct traffic over the stronger central section of the bridge using permanent traffic signals.
- A monitored traffic signal trial took place in summer 2022 to assess traffic, air quality and noise impacts. Trial results were presented at a public exhibition in May 2023.
What the scheme includes
- Permanent 3‑way traffic signals controlling vehicle movements across Islip Bridge
- Narrowed carriageway (3.0m) to protect the bridge structure
- New 1.5m wide footway on the west side of the bridge
- Traffic calming on the southern approach
- Drainage repairs, resurfacing, footway improvements and new road markings
- Mill Street made one‑way in advance of the scheme
When will the work take place
- Start date: Monday 29 June 2026
- Duration: Approximately 10 weeks (subject to weather and site conditions)
The works have been programmed to take place during the summer school holiday period, when traffic flows are lower. This helps reduce the impact on the travelling public and increases the likelihood of better weather, reducing the risk of delays.
We recognise the scheme will cause disruption and will do everything possible to complete the work as safely and as quickly as possible.
Traffic management and bridge closure
To deliver the works safely and efficiently, construction will be carried out in two phases:
Phase 1: 29 June – 3 July 2026
- Temporary traffic signals for site setup and preparation works
Phase 2: 6 July – 28 August 2026
- Full closure of Islip Bridge to all vehicles
- Signed diversion route in place
- Pedestrian and cyclist access maintained at all times
There will be no vehicle access across the bridge during the closure, including buses. Staff will be present at either end of the closure to manage safety and provide assistance. Access to nearby properties and businesses will be accommodated where possible, though short delays may occur.
Public transport
During the bridge closure:
- The H5 service (Bicester – JR Hospital) will continue to serve Islip from the north.
- Buses will follow the signed diversion via Kidlington Road, Bicester Road, the A40 and Barton, and vice versa.
- A shuttle bus will operate between Barton and the bus stop on the south side of Islip Bridge.
- Pedestrian and cyclist access across the bridge will remain available throughout.
More information
Why are the works being carried out during the summer?
The works are scheduled during the summer school holiday period when traffic levels are lower. This helps reduce disruption and improves the chances of good weather, reducing the risk of delays.
Why can’t vehicles cross the bridge during the works?
A full vehicle closure is required to carry out the works safely and efficiently. Keeping the bridge closed avoids repeated temporary closures and helps reduce the overall programme length.
Will pedestrians and cyclists still be able to cross the bridge?
Yes. Pedestrian and cyclist access will be maintained at all times throughout the works.
How long will the bridge be closed to vehicles?
The overall project will last around 10 weeks. The bridge will be fully closed to vehicles from 6 July to 28 August 2026
Will buses still serve Islip during the closure?
Yes. The H5 bus service will continue serving Islip from the north, following the diversion route via Kidlington Road, Bicester Road, the A40 and Barton. A shuttle bus will operate between Barton and the south side of the bridge.
Why are traffic signals being installed permanently?
Traffic signals allow vehicle loads to be focused on the strongest part of the bridge, protecting the structure while also improving pedestrian safety and discouraging rat‑running through the village.
How will access to homes and businesses be managed?
Staff will be on site to manage access and safety. Every effort will be made to accommodate access to nearby properties and businesses, although short delays may sometimes be unavoidable.
