High Quality Content by WIKIPEDIA articles! The Intermodal Surface Transportation Efficiency Act of 1991 (Public Law 102-240; ISTEA, pronounced Ice-Tea) 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. It 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 (TEA-21) in 1998, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) in 2005, and the Moving Ahead for Progress in the 21st Century Act (MAP-21) in 2012. ISTEA also provided funds for non-motorized commuter trails; the first trail to be so funded was the Cedar Lake Regional trail which was built in 1995 in Minneapolis, Minnesota.
