Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps her Department is taking to ensure that major regional transport infrastructure projects are delivered on schedule and within budget; what oversight mechanisms exist for monitoring project delivery; and what lessons have been learned from delays to major urban transport schemes.

The Government recognises the importance of ensuring that delivery of large infrastructure projects is underpinned by prudent spending, taxpayer value for money, and efficiency. Local Transport Authorities (LTAs) and Mayoral Combined Authorities are primarily responsible for delivering major regional transport infrastructure projects using devolved funding. The Department maintains oversight through established governance and assurance processes, including reporting on progress, risks, costs and delivery performance.

For the largest and most complex projects the Department retains investment decision-making and works closely with the LTAs to bring projects forward and monitor progress. The Department also provides funding to support LTA capacity and capability to develop and deliver schemes. In addition, the department continues to apply lessons from previous major urban transport schemes, including strengthening project governance, improving risk management, and ensuring clearer sequencing and accountability throughout delivery - to inform both current schemes and the design of future programmes.

The Department also published the James Stewart Review (June 2025), which identified lessons from delivery challenges, including delays to complex schemes. All recommendations have been accepted and are being implemented across the Department’s portfolio to improve consistency and delivery performance. The Department for Transport is using key findings to strengthen oversight of major transport infrastructure delivery, with a focus on improving cost estimation, scheduling, governance, assurance, and commercial delivery.
