This is the 11th in a series of combined documents the U.S. Department of Transportation (DOT) has prepared to satisfy requirements for reporting to Congress on the condition, performance, and future capital investment needs of the Nation's highway and transit systems. This report incorporates highway, bridge, and transit information required by 23 United States Code (U.S.C.) �503(b)(8) and transit system information required by 49 U.S.C. �308(e). Beginning in 1993, the Department combined two separate existing report series that covered highways and transit to form this report series; before then, 11 reports had been issued on the condition and performance of the Nation's highway systems, starting in 1968. Five separate reports on the Nation's transit systems' performance and conditions were issued beginning in 1984.This 2015 Status of the Nation's Highways, Bridges, and Transit: Conditions and Performance report to Congress (C&P report) draws primarily on 2012 data. The 2013 C&P report, transmitted on January 14, 2014, was based largely on 2010 data.In assessing recent trends, many of the exhibits presented in this report present statistics for the 10 years from 2002 to 2012. Other charts and tables cover different periods, depending on data availability and years of significance for particular data series. The prospective analyses presented in this report generally cover the 20-year period ending in 2032.
