Delayed A40 Park and Ride Costs Still Undetermined: Update

Oxfordshire County Council has confirmed that the full cost of keeping the unfinished Eynsham Park and Ride secure until its delayed opening in 2028 "has not yet been determined" – despite the facility standing empty since completion in January 2024.

The clarification came in response to a Freedom of Information request from the Oxford Mail, which asked the authority to provide updated figures for maintaining and securing the 850-space car park on the A40. The site, built as part of the wider A40 improvement programme, has been widely dubbed a "car park to nowhere" because vehicles cannot access it until a new junction is built.

In its response, the council said ongoing security and maintenance costs were originally covered under the initial delivery contract, meaning the authority is "not incurring any maintenance costs" at present. However, when asked to estimate the total expense of looking after the unused facility until it opens in summer 2028, the council said the amount had "not yet been determined."

That vagueness stands in sharp contrast to earlier figures suggesting the site costs nearly £10,000 a month to secure. The discrepancy has raised fresh questions about how the county is budgeting for a project that has repeatedly slipped down the timeline.

The Eynsham Park and Ride is a key component of the wider £126 million A40 improvement scheme, which was originally designed to ease congestion and improve public transport between West Oxfordshire and Oxford. The facility was built ahead of schedule to lock in construction prices, but it has remained out of use because the connecting junction was not included in the initial phase of work.

The county council said delays in the wider project have not pushed the scheme over budget, adding that costs remain "under review" and that the programme is "currently within budget." That statement will likely be scrutinised by local campaigners, who have long argued that phased delivery – combined with soaring inflation and rising construction prices – would ultimately make the project more expensive.

Critics have pointed to the decision to build the park and ride before the road access was approved as a false economy. The council has previously defended the move, claiming that proceeding with construction despite the missing junction "saved taxpayers millions of pounds in additional inflationary and construction costs." But with the site now idle for over a year and closure expected to stretch into 2028, those savings are becoming harder to verify.

When asked whether planning delays, planning conditions, or other unforeseen issues had inflated the overall cost, the council did not offer a direct answer. Instead, it repeated that the project was still within budget and that a full cost review would follow as the next construction phase gets underway.

That next phase moved closer to reality earlier this year when councillors approved a £70 million contract with Balfour Beatty to deliver major works between Eynsham and Wolvercote. This stage will include connecting the park and ride to the A40, upgrading a four-and-a-half-mile stretch of road, adding new bus lanes, improving crossings, and building better walking and cycling routes.

Construction is now expected to begin in spring 2027, with the park and ride opening in summer 2028. The entire A40 improvement programme is projected to continue until summer 2029 – more than a decade after the scheme was first conceived.

The project was originally funded through a mixture of government grants, local growth funding, and developer contributions. It was intended to deliver the park and ride and road improvements simultaneously, but "exceptional inflationary pressures in 2022" forced a major review. Rising costs led to a scaled-back, phased approach that separated the car park from the main roadworks.

Infrastructure experts say this case highlights a recurring problem in UK project delivery: committing to a visible but unusable asset years before the surrounding network is ready. Oxfordshire County Council is not alone in facing this challenge, but the A40 park and ride has become one of the most high-profile examples because of its prominent position on a busy trunk road.

A council spokesperson said the authority remains committed to delivering the full A40 scheme and will provide further updates as the main works progress. They did not set a date for publishing the long-awaited total cost figure.

In the meantime, residents and drivers passing the Eynsham site are likely to keep seeing the same sight – an empty, fully constructed car park, sealed off from the road, with no opening date that the council is willing to attach a final bill to.

The FOI response, while confirming that no maintenance invoices are currently being paid, leaves unanswered the most important question: how much will taxpayers ultimately spend on a facility that has been unusable for more than a year and will remain closed for at least another two?

Until the council provides a definitive figure, the A40 park and ride will continue to be a symbol of delayed infrastructure and opaque budget planning. For commuters hoping for an improved journey into Oxford, the wait – and the uncertainty – continues.
