  • Description: Generally negative prevailing views of infrastructure delivery performance is sclerotic and in need of an evidence-based reappraisal. This study evaluated the project delivery performance of National Highways, the government company responsible for delivering England's road investment strategy which completed 138 road/highway major schemes over 16 years between 2001 and 2016.93% of major schemes had a benefit-cost ratio, BCR, of 1 or more which means most projects delivered more benefit than their cost. 69% have a high BCR of 2 or more, delivering benefits at least twice the cost of the project. Typical cost performance was a 2.4% overrun with 42% of projects delivered on or under budgeted cost. The overall value of cost overruns was compensated for by the value of underruns so the net cumulative balance was below zero. Cost performance improved over time, with a typical cost underrun of −6% observed in projects completed in the latter half of the studied time period. The improvement to delivery cost performance is most likely to be explained by changes in policy and practice, including: improved estimation of costs; Strengthened appraisal and approval; Developing procurement strategy; Improving programme management; Implementing lessons learned. •93% of English roads major schemes have a positive BCR and typically delivered within budget. Changes to policy and practice improved cost performance over time.
