Intermodal Surface Transportation Efficiency Act
The Intermodal Surface Transportation Efficiency Act of 1991 is a United States federal law that posed a major change to transportation planning and policy, as the first U.S. federal legislation on the subject in the post-Interstate Highway System era.
Objective
The Act presented an overall intermodal approach to highway and transit funding with collaborative planning requirements, giving significant additional powers to metropolitan planning organizations. Signed into law on December 18, 1991 by President George H. W. Bush, it expired in 1997. It was preceded by the Surface Transportation and Uniform Relocation Assistance Act of 1987 and followed by the Transportation Equity Act for the 21st Century in 1998, the in 2005, and the Moving Ahead for Progress in the 21st Century Act in 2012. ISTEA also provided funds for the conversion of dormant railroad corridors into rail trails; the first trail to be so funded was the Cedar Lake Regional Rail Trail, built in 1995 in Minneapolis, Minnesota.High Priority Corridors

High-speed rail corridors
The legislation also called for the designation of up to five high-speed rail corridors. The options were studied for several months, and announced in October 1992. The first four were announced by United States Secretary of Transportation Andrew Card, while the last was announced by Federal Railroad Administration head Gil Carmichael.- October 15, 1992: The Midwest high-speed rail corridor with three links from Chicago, Illinois to Detroit, Michigan, St. Louis, Missouri, and Milwaukee, Wisconsin.
- October 16, 1992: The Florida high-speed rail corridor linking Miami with Orlando and Tampa.
- October 19, 1992: The California high-speed rail corridor linking San Diego and Los Angeles with the San Francisco Bay Area and Sacramento via the San Joaquin Valley.
- October 20, 1992: The Southeast high-speed rail corridor connecting Charlotte, North Carolina, Richmond, Virginia, and Washington, D.C..
- October 20, 1992: The Pacific Northwest high-speed rail corridor linking Eugene and Portland, Oregon with Seattle, Washington and Vancouver, British Columbia, Canada.
Jeff Morales one of the principal drafters of this bill, is currently serving as CEO of the California High-Speed Rail Authority, which is currently constructing a high-speed rail line along the route originally proposed in this bill.
