This synthesis reports bridge inspection practices in the United States and selected foreign countries. The synthesis is a collection of information on formal inspection practices of departments of transportation (DOTs). These are primarily visual inspections and they provide data to bridge registries and databases. For U.S. inspection practices, this synthesis reports on inspection personnel, inspection types, and inspection quality control and quality assurance. Staff titles and functions in inspection programs are reported, together with qualifications and training of personnel, formation of inspection teams, and assignment of teams to bridges. Inspection types are described in terms of their scope, methods, and intervals. Quality control and quality assurance programs are reviewed in terms of the procedures employed, staff involved, quality measurements obtained, and the use of quality findings in DOT inspection programs. Foreign practices are presented in the same organization of inspection personnel, types, and quality programs. Comparisons of U.S. and foreign inspection practices are included. Information was obtained from a questionnaire sent to U.S. state transportation departments, similar questionnaires modified individually for transportation agencies in selected foreign countries, and formal documents used by transportation departments and agencies. These documents primarily included bridge inspection manuals, inspection training manuals, and technical memoranda, but also included blank forms for inspections, DOTs job descriptions for inspectors, and descriptions of inspection training courses. Overall, this synthesis includes information from forty U.S. state transportation departments and from roads agencies in eight foreign nations (Denmark, France, Finland, Germany, Norway, South Africa, Sweden, and the United Kingdom). The synthesis also includes, in an appendix, information from a few provincial and municipal transport agencies in Canada.

England is a litter-ridden country compared to most of Europe, North America and Japan. Levels of litter in England have hardly improved in the past 12 years and the best estimates are that litter costs the taxpayer between £717 and £850 million a year to clear up. Change is needed. There has been a 20% increase in fast-food litter in the last year. The Government should bring forward legislation requiring all shops, restaurants and retail food outlets to keep the perimeters of their premises free from litter. Responsible businesses are already doing this. In addition, the fast-food industry should introduce 'on-pack' information on all branded take-away and fast-food packaging to remind consumers to dispose of litter responsibly. The most frequently littered items are chewing gum and smokers' materials. Chewing gum and staining are difficult and costly to remove. This was a matter of considerable concern upon which the Committee deliberated at length. Levels of fly-tipping increased by 20% in the last year. There were 852,000 reported incidents but only 2,000 convictions in the courts. The Government should introduce a fixed penalty notice for fly-tipping for household items - the bulk of the incidents - and the industry must introduce a scheme to take away unwanted household appliances and furniture when replacements are delivered. In the end it is individuals who litter and fly-tip their unwanted goods, and it is this behaviour which needs to change. The Committee support a variety of behaviour-changing activities and campaigns to prevent littering.

'Privately Financed Roads in Britain: A Policy Assessment' critically examines the role of private finance in the construction, operation, maintenance and management of modern highways. The focus is on the UK's Private Finance Initiative (PFI) yet many of the lessons learned retain a currency in the context of international public-private partnerships. Separate chapters cover: Public Policy Objectives; Key Project-Level Risks (construction and traffic); Value for Money and Public Sector Comparators; The Financial Architecture of Private Sector Road Operating Companies; Strengths and Weaknesses of the Privately-Financed Roads Model; Alternative Debt/Equity Structuring; and Containing Private Financing Costs.
