Escalating costs across the whole of the Highways Agency programme, including the M1 project, on which costs had risen to £5.1 billion, as well as increasing opposition to major road expansion, as well as criticisms by the Transport Select Committee and the National Audit Office, led to wide-ranging re-assessments of the Agency's project costs. Widening was scaled back to the Junctions 6A to 10 scheme that was already in progress, and from Nottingham and Mansfield (Junctions 25–28), and hard shoulder running was to be used for other sections.
