Oxford (Oxford Daily News) February 28, 2026 – Donnington Bridge, a vital crossing over the River Thames linking Abingdon Road to Iffley Road, may require extensive repairs or full replacement following a recent structural evaluation by Oxfordshire County Council engineers. The bridge has operated under a 7.5-tonne emergency weight restriction since August 2024, prohibiting heavy vehicles and full-sized buses, which has disrupted local bus services including the number 46 route.

Preliminary assessments indicate damaged post-tensioned cables necessitate new installations or a complete rebuild, with costs estimated at £4 million for repairs taking two years, or up to £30 million for replacement with extended timelines. Labour councillor Brad Baines, representing the Isis division, has urged swift action from the council’s cabinet member Andrew Gant, highlighting the ongoing inconvenience to residents. A council spokesperson confirmed site investigations are underway, with feasibility studies expected by spring or summer 2026 to determine the path forward.

What Triggered the Emergency Weight Restriction on Donnington Bridge?

The 7.5-tonne weight limit on Donnington Bridge was imposed as an emergency measure in August 2024 after ongoing monitoring revealed weaknesses in the structure. As reported by BBC News, Oxfordshire County Council engineers recommended the restriction “as a precautionary measure” while checks are carried out on hidden and currently inaccessible elements of the bridge. This followed routine inspections that identified the need for further assessment of critical materials, leading to the prohibition of vehicles over 7.5 tonnes, including goods vehicles and public service vehicles like full-sized buses.

The Oxford Clarion detailed in its 23 August 2024 weekly edition that the decision came from continuous monitoring work showing structural concerns, prompting immediate action to ensure public safety.

Councillor Andrew Gant, Oxfordshire County Council’s Cabinet Member for Transport Management, later acknowledged the inconvenience in an October 2024 statement on the council’s news site, saying: “The absence of buses on Donnington Bridge Road for essential safety reasons has been a huge inconvenience for people in this area who rely on public transport, especially those who find it difficult to walk longer distances to use alternative bus services.”

The restriction remains in place until at least 28 February 2026 or until the council is satisfied that necessary works are completed, as noted in a public notice portal entry.

How Has the Weight Restriction Impacted Local Bus Services?

The restriction has forced the rerouting of three bus routes, the 46, BB1A, and ST1 preventing them from operating via Weirs Lane and Donnington Bridge Road. As detailed by BBC News, the number 46 bus service now diverts through Iffley Road, breaking direct connections between Iffley Road and Abingdon Road to shops at Cowley Centre and medical and leisure facilities on Abingdon Road. This has particularly affected residents in Donnington Bridge Road, Florence Park, and surrounding areas who depend on public transport.

In response, Oxfordshire County Council introduced the off-peak shuttle service 46A using its own minibus fleet, starting Monday 14 October 2024.

Councillor Andrew Gant stated on the council’s website: “Our officers have worked hard to try to alleviate some of the problems and we’re delighted to be able to unveil this shuttle service to connect passengers with the places they need to be. By using the council’s own vehicles when they are not in use elsewhere, we are able to reduce the costs involved, improving value for money.”

The shuttle comprises four return journeys Mondays to Fridays between 10:30am and 2:30pm, linking Cowley Centre, Florence Park, Donnington Bridge, and Speedwell Street in Oxford city centre, timed to connect with the main 46 service at Cowley Centre. Timetables are available via online journey planners and bus stops. Labour councillor Brad Baines, as reported by BBC News on 1 March 2026, criticised the ongoing disruptions, stating residents “cannot afford to wait a further two years for the return of the 46 to Abingdon and Donnington Bridge roads.”

What Do Recent Structural Assessments Reveal About the Bridge?

A recent evaluation by the structural engineering team at Oxfordshire County Council has concluded that Donnington Bridge requires repairs, including the installation of new cables, or potentially a total replacement before full-sized buses can resume routes. According to BBC News reporter’s coverage on 1 March 2026, preliminary assessments indicate that “certain components of the bridge may be critical if the post-tensioned cables are found to be damaged.”

The spokesperson for the council elaborated: “However, their exact condition remains uncertain and is challenging to assess without risking structural harm.”​

The bridge, spanning the River Thames and connecting key roads, underwent these checks amid the weight limit, revealing the need for advanced monitoring until reinforcement or replacement occurs. AOL News echoed this, noting the bridge “may need lengthy repairs or have to be replaced entirely due to its condition.” Site investigations by the council’s contractor are now in progress to clarify the urgency, with feasibility studies to evaluate options and costs slated for spring or summer 2026. Decisions on strengthening or replacing will follow these results later in 2026. OxonLive’s Facebook post from 28 February 2026 highlighted councillor concerns over the two-year repair timeline.

Who Is Leading the Call for Urgent Action on Repairs?

Labour councillor Brad Baines has been vocal, contacting cabinet member Andrew Gant to demand swift repairs. As reported by BBC News, Councillor Baines stated that current estimates suggest the council may have to pay about £4m for repair works, which would take two years, adding that replacing the bridge would extend the timeline and could cost as high as £30m.

He warned: “Residents cannot afford to wait a further two years for the return of the 46 to Abingdon and Donnington Bridge roads. The county council needs urgently to work with local operators to establish a full timetable service using minibuses.”

Councillor Baines has launched a petition advocating for the bridge’s repair, emphasising collaboration with bus operators. In contrast, the council spokesperson outlined a measured approach, noting engagement with contractors for investigations.

An agenda item from Oxfordshire County Council’s Delegated Decisions by Cabinet Member for Transport on their portal reflected broader concerns, with the Chair noting: “The Chair noted the weight restrictions in place over Donnington Bridge and reflected that bridges across Oxfordshire needed repair but there was limited funding.”

This underscores the financial pressures amid multiple infrastructure needs.

What Are the Estimated Costs and Timelines for Fixing the Bridge?

Repair works are preliminarily estimated at £4 million, with a duration of two years, while a full replacement could reach £30 million with significantly longer disruptions.

BBC News quoted Councillor Brad Baines: “He said current estimates suggested the council may have to pay about £4m for repair works, which would take two years. He added that replacing the bridge would extend the timeline and could incur costs as high as £30 million.”

These figures stem from the council’s structural team’s evaluation.​

The council’s spokesperson confirmed that feasibility studies by spring or summer 2026 will refine these estimates and options. Advanced monitoring will continue in the interim. Councillor Baines stressed urgency to avoid prolonged waits for residents. Historical context from the August 2024 imposition shows costs were not then quantified, but the 2026 assessments provide the first detailed projections. Funding limitations were noted in council minutes, with the Chair highlighting repairs needed across Oxfordshire bridges.

How Is the Council Responding to the Bridge’s Critical Condition?

Oxfordshire County Council is commissioning its contractor for site investigations to assess post-tensioned cables without risking further damage. The bridge will receive advanced monitoring until resolved.​

Earlier, in October 2024, the council mitigated bus impacts via the 46A shuttle, as per their news release. Public notices extended the weight restriction formally from 30 September 2024, citing “critical bridge construction elements to be reviewed/assessed which is anticipated to be undertaken over a lengthy period.” Councillor Andrew Gant praised the shuttle’s value for money. Responses to Councillor Baines’ outreach are pending, but studies are prioritised for 2026 decisions.

What Are the Broader Impacts on Oxford Residents and Traffic?

Residents face broken direct bus links to essential services, exacerbating mobility issues for those unable to walk further. The reroute via Iffley Road has isolated Donnington Bridge Road areas from Cowley Centre shops and Abingdon Road facilities. Councillor Brad Baines, in BBC reporting, emphasised: “Residents should not have to wait an additional two years for bus services to be reinstated.” The shuttle provides partial relief, but full services await repairs.

Traffic sees heavy vehicles diverted, with signs indicating the 24-hour restriction. Local groups like the Oxford Pedestrians Association discussed works on Facebook as of 28 February 2026. Broader council agendas note strained bridge maintenance budgets. The Oxford Local Plan 2036 policies on highways (M1, RE7) frame assessments, as in related planning docs. No accidents reported directly, but safety drove the measures.

When Will Decisions Be Made on Donnington Bridge’s Future?

Feasibility studies and site investigations are targeted for completion by spring or summer 2026, with decisions expected later that year. This aligns with the weight restriction’s extension to at least February 2026.

Councillor Baines pushes for interim minibuses via petition. Historical delays, like Botley Road’s extension to August 2026, suggest timelines may slip. Council agendas indicate ongoing deliberations. Monitoring persists.

Could Similar Issues Affect Other Oxford Bridges?

While specific to Donnington Bridge, council minutes reveal wider concerns. Botley Road Bridge replacement ties into Oxford Station upgrades, delayed to August 2026. Donnington’s post-tensioned cables highlight aging infrastructure risks. No other immediate closures reported, but monitoring is routine. Councillor Gant focused on Donnington mitigations.

Planning reports for nearby Donnington Recreation Ground affirm highways safety under Local Plan policies, indirectly supporting bridge context. Residents watch for funding allocations in 2026 budgets.
