This report details the conditions of the nation's 3.9 million miles of roads and bridges, funding and use of the system, and travel by the nation's 190 million cars, trucks and buses and the impact of this travel on air quality. The report is based on surveys of state Departments of Transportation and data collected from the Federal Highway Administration (FHWA), the U.S. Department of Transportation (DOT), and the U.S. Environmental Protection Agency (EPA). Highlights from the report are as follows: The total 1992 capital improvement expenditure for our nation's road and bridge system was $38.7 billion -- $12.9 billion below the $51.6 billion per year needed to maintain current conditions and performance. This underinvestment in our nation's roads and bridges is further hampered by the diversion of $14.4 billion in highway user fees (such as motor fuel and registration taxes) siphoned away from road and bridge improvements to non-highway projects. The current backlog of existing road and bridge needs on major routes (arterials and collectors) is estimated to be $290 billion. More than half -- 55.7% -- of the nation's major roadways are in poor or fair condition and are in need of immediate repair. Nearly 200,000 bridges -- or 34.6% -- are in substandard condition either because they are obsolete or are structurally deficient. Capital investment per 1,000 vehicle miles of travel on the nation's highways in inflation adjusted dollars decreased 14.2% from 1986 to 1992. The proposed National Highway System (NHS) will be the foundation and backbone of the nation's transportation system in the 21st century. Consisting of 159,000 miles of mostly existing roadway, the NHS would comprise only 4% of the nation's roads but carry 40% of total vehicle traffic and 75% of heavy truck travel. If Congress does not adopt the NHS by September 30, 1995, the states will lose $6.5 billion in annual funding for NHS and Interstate routes, jeopardizing 230,000 jobs nationwide.
