摘要：	Optimization of bridge selection and design traditionally has been sought in terms of the finished structure. This study presents a more comprehensive risk-based analysis that includes user costs and accidents during the construction phase. Costs for bridge projects include actual comprehensive costs, both to the funding agency, the Colorado Department of Transportation (CDOT), and to the public at large, including assessments associated with accidents and user delay times during the construction phase. Bridges were selected to represent a cross section of structure types, ADT (average daily traffic volumes), bridge overall length and CDOT region. A total of 43 bridges were targeted for study, and data were able to be compiled on 20 of these. A questionnaire was developed and sent to CDOT bridge personnel, in order to collect general project information as well as detailed information on construction duration, construction traffic control plans (including detour types and mileposts, time of day scheduling and speed reductions), observed congestion and accidents during construction. / Title Note: Final rept. / Supplementary Notes: Sponsored by Colorado Dept. of Transportation, Denver. and Federal Highway Administration, Denver, CO.
