1999 Status of the Nation's Highways, Bridges and Transit: Conditions and Performance [open pdf - 5MB]
"This document is intended to provide Congress and other decision makers with an objective appraisal of highway, bridge and transit finance, physical conditions, operational performance, and future investment requirements. This report offers a comprehensive, factual background to support development and evaluation of legislative, program, and budget options at all levels of government. It also serves as a primary source of information for national and international news media, transportation associations, and industry. This report consolidates conditions, performance, and finance data provided by States, local governments, and mass transit operators, to provide a national level summary. Some of these underlying data are available through the Department's regular statistical publications. The future investment requirements analyses are developed specifically for this document and provide national level projections only. The Department does not project future investment requirements for individual States or localities. Section 5102 of TEA-21 designated the highway and bridge portion of this document as the Infrastructure Investment Needs Report, and required several changes in the content. This edition of the report has responded to these requirements by adding estimates of the current backlog of cost-beneficial highway and bridge projects, and adding a table to each chapter that directly compares the key statistics from the current report with those from the 1997 edition. An investment requirements scenario showing the costs of maintaining the physical conditions of the highway system has been added, to improve comparability of this report to the 1993 and 1995 versions and to the bridge and transit investment requirements scenarios."
