A supercorridor is a proposed new type of transportation infrastructure in the United States. A supercorridor would use swaths of land up to 1,200 feet (370 m) wide to carry parallel links of freeways, rails, and utility lines. The freeway portions would be divided into two separate elements: truck lanes and lanes for passenger vehicles. Similarly, the rail lines in the corridor would be divided among freight, commuter, and high-speed rail. Services expected to be carried in the utility corridor include water, electricity, natural gas and petroleum, plus
