A £40 million motorway junction, dubbed Britain's most expensive dead end, now requires repairs despite not having carried a single vehicle in the six years since its construction began. The 'ghost junction,' located off Bristol's M49, was designed to provide access to a distribution center for retailers including Amazon, Tesco, Lidl, Next, DHL, and The Range.
Construction on the junction faced years of setbacks and remained incomplete, with motorists encountering a dead end. Despite never officially opening, defects were noted as early as 2021, less than two years after construction started. These initial issues, including loss of topsoil and surface cracking, were monitored by National Highways but later investigations commissioned in 2025 identified geotechnical problems.
Roads minister Justin Madders stated in the House of Commons that the full extent of the issues and their root cause are still under investigation, pending engagement with the contractor. The junction, situated between the M5 at Avonmouth and the M4 Prince of Wales Bridge, was intended to facilitate traffic to industrial sites in South Gloucestershire's Avonmouth Severnside Enterprise Area. Lorries currently have to travel through local villages to reach the business park.
Liberal Democrat MP Claire Young, representing Thornbury and Yate, has referred to the site as a 'ghost junction' and described the delays as an 'utterly unbelievable situation.' She noted that National Highways has acknowledged the defects require repair before the junction can open safely. Young also highlighted that while the junction is isolated, nearby roads like the A403 and B4461 are experiencing misuse by heavy goods vehicles, causing difficulties for residents, agricultural vehicles, and horse riders.
Minister Madders confirmed that the government has provided approximately £10 million to support the development of a link road to the junction. He emphasized that while funding has limits, the government will prioritize resolving the technical issues. The approach, he stated, is for National Highways to identify the correct engineering solution, agree on a delivery route that protects taxpayer interests, and provide realistic timelines. However, a definitive timeline for the remedial works is not yet possible, as responsibility, liability, and funding are subject to ongoing discussions. Madders added that the public views all related infrastructure projects as a single, delayed outcome and stressed the need for coherent infrastructure management with clear accountability and communication.
