This article was adapted from and summarizes the 1993 Highway, Bridge and Transit Conditions and Performance (C&P) Report. The C&P report is a biennial report that provides Congress and other decision makers with an ongoing appraisal of the current condition and performance of the U.S. highway system. The report covers all of the nation's roads and bridges, including all public-use highway and bridge infrastructure and all privately owned toll facilities. Among other subjects, the report provides assessments of system characteristics, trends, highway investment, and investment levels needed to meet future demands. This C&P report includes, for the first time, information on environmental impacts. All investment estimates are for the period January 1, 1992, through December 31, 2011, and are expressed in 1991 dollars. |
