The state and local share would be about $2 billion. To finance the system, the Clay Committee proposed creation of a Federal Highway Corporation that would issue bonds worth $25 billion. Revenue from gas taxes would be dedicated to retiring the bonds over 30 years. Because traffic would continue to increase during that period, revenue would also go up, and a hike in the gas tax would not be necessary.

Overview

The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, is a network of controlled-access highways that forms part of the National Highway System in the United States. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico.

History

The United States government's efforts to construct a national network of highways began on an ad hoc basis with the passage of the Federal Aid Road Act of 1916, which provided $75 million over a five-year period for matching funds to the states for the construction and improvement of highways. The nation's revenue needs associated with World War I prevented any significant i…

Standards

The American Association of State Highway and Transportation Officials (AASHTO) has defined a set of standards that all new Interstates must meet unless a waiver from the Federal Highway Administration (FHWA) is obtained. One almost absolute standard is the controlled access nature of the roads. With few exceptions, traffic lights (and cross traffic in general) are limited to toll booths

Numbering system

The numbering scheme for the Interstate Highway System was developed in 1957 by the American Association of State Highway and Transportation Officials (AASHTO). The association's present numbering policy dates back to August 10, 1973. Within the contiguous United States, primary Interstates—also called main line Interstates or two-digit Interstates—are assigned numbers les…

Statistics

• Heaviest traveled: 374,000 vehicles per day: I-405 in Los Angeles, California (2008 estimate ).
• Highest: 11,158 feet (3,401 m): I-70 in the Eisenhower Tunnel at the Continental Divide in the Colorado Rocky Mountains.
• Lowest (land): −52 feet (−16 m): I-8 at the New River near Seeley, California.

Impact and reception

Following the passage of the Federal Aid Highway Act of 1956, the railroad system for passengers and freight declined sharply, but the trucking industry expanded dramatically and the cost of shipping and travel fell sharply. Suburbanization became possible, with the rapid growth of larger, sprawling, and more car dependent housing than was available in central cities. Tourism dramatically expanded as well, creating a demand for more service stations, motels, restaurant…

Origins of The Interstate System

  • In the very early part of the last century, national highway policy was focused on getting farmers out of the mud and getting their produce to market.

In 1921, the focus shifted as Congress reshaped the program to restrict Federal-aid to a limit...
