Commercialising the management and maintenance of trunk roads in the United Kingdom

Public funding of new infrastructure from money raised through taxes or borrowing has been questioned globally in recent years. One alternative solution has been to finance major capital projects through Build, Operate & Transfer (BOT) schemes. In the United Kingdom, the Private Finance Initiative (PFI) has become established as the procurement method of choice for many projects and services in central and local government. It is a natural development of other changes in government administration which have been introduced over the past few years. Projects delivered in this way enable government to become a buyer of services on behalf of the public rather than a direct provider of those services to the public, taking advantage of private sector management skills and resources in their delivery. The PFI has demonstrated its ability to deliver value for money solutions in projects across a range of capital-intensive public services, but the greatest success in delivering projects has been in the transport sector. This paper outlines how the British Government's Highways Agency has restructured and commercialised the management and maintenance of the strategic road network for which it is responsible, and how it has been at the forefront of developing successful privately financed projects. The paper explains the Agency's particular version of BOT – Design, Build, Finance and Operate (DBFO) projects. These projects are delivering new and improved road construction and maintenance, providing better services to users of the country's strategic road network and achieving significant value for money savings for taxpayers.
