The reopening of Osney Bridge in Oxford has been delayed again, with Thames Water now planning to keep a lane closure in place until 18 September, just days before Network Rail is expected to reopen Botley Road.
The latest delay comes after more than five years of work on the Thames crossing and means motorists, cyclists and pedestrians will face continued disruption at a time when the surrounding road network is already undergoing major changes.
Thames Water had previously been expected to complete its work on the bridge this summer, broadly coinciding with the planned reopening of Botley Road.
But the water company has now said that structural complications discovered during the project have required its designs to be revised.
“Due to structural complications that were identified on Osney Bridge, Thames Water was required to revise its designs to ensure the trunk mains could be replaced safely, while complying with the bridge’s structural requirements and avoiding any damage,” a spokesperson said.
“We are sorry for the inconvenience caused and are working to complete the project as quickly as possible, in tandem with the completion of work being carried out at Oxford Train Station to minimise disruption.”
A key route through west Oxford
Osney Bridge currently has a lane, cycle path and pavement closure on its northern side, with three-way traffic lights controlling vehicles between the Botley Road closure, Abbey Road and Osney Island.
The work dates back to April 2021, when an Environment Agency boat struck a water pipe beneath the bridge. The subsequent project has involved repairs to the water main as well as work to address what Thames Water has described as the poor condition of the footpath structure.
Signage at the bridge had given 28 August as the expected completion date, with a note saying the work would finish sooner if possible.
Last month, Thames Water was granted a two-week extension by Oxfordshire County Council, taking the permitted period for the work to 10 September. At the time, the company said the additional time would be used only if necessary.
The latest timetable extends the lane closure beyond that date.
Thames Water said it was working with Oxfordshire County Council to keep the lane closure in place until 18 September, with traffic expected to flow freely again from 20 September.
The company also expects to carry out overnight lane closures, from 8.00pm to 6.00am, for around three to four weeks if the work proceeds as planned.
Timing raises wider concerns
The timing is significant because Osney Bridge is expected to play a greater role in west Oxford’s road network once Botley Road reopens.
Network Rail’s long-running closure of Botley Road has been linked to the redevelopment of Oxford station. Its reopening has itself been delayed, with gas works among the issues affecting the timetable.
The current plan is for Botley Road to reopen on 20 September.

When it does, changes to traffic arrangements will mean Botley Road becomes the route for drivers without permits, or those who have exhausted their permitted journeys, travelling by car to the Westgate area.
The campaign group Reconnecting Oxford has highlighted the potential consequences of the overlapping delays.
“Thames Water were supposed to have finished work on the Botley Road yesterday,” the group said in a social media post. “This clearly hasn’t happened.”
The group added that, within weeks, the route would be the only way for out-of-town shoppers to reach Westgate by car without a permit.
The extended Osney Bridge works have also drawn criticism from local councillors. County and city councillor Susanna Pressel has previously described the situation as frustrating for both drivers and cyclists facing delays caused by the bridge works.
Five years after the damage
The latest timetable marks more than five years since the incident that triggered the work.
In April 2021, an Environment Agency boat hit a water pipe beneath Osney Bridge, damaging the infrastructure. The subsequent repairs have become part of a much wider period of disruption for west Oxford, where the closure of Botley Road has already reshaped traffic patterns and access to the city centre.
Thames Water said its revised approach is intended to allow the trunk mains to be replaced safely while taking account of the bridge’s structural requirements.
The company says the aim is now to complete the work in time for traffic to flow freely when Botley Road reopens.
For people travelling through west Oxford, however, the significance of the latest deadline will be measured less by the timetable than by whether the bridge is finally clear when the city’s road network enters its next phase of change.
