Chicago Skyway

The Chicago Skyway, also known as Chicago Skyway Toll Bridge System, is a 7.8-mile-long (12.6 km) toll road in Chicago, Illinois, United States, carrying Interstate 90 from the Indiana Toll Road to the Dan Ryan Expressway on Chicago's South Side leading into the Chicago Loop.

The main feature of the Skyway is a 1⁄2-mile-long (0.80 km) steel truss bridge, known as the "High Bridge". The toll bridge spans the Calumet River and Calumet Harbor, a major harbor for industrial ships. The main span is 650 feet (200 m) long, provides for 125 feet (38 m) of vertical clearance, and is the highest road in Chicago. The bridge is heavily documented by the Library of Congress Historic American Engineering Record Survey number HAER IL-145. The survey consists of nearly 30 data pages and 21 black and white images.

Between 2001 and 2004 authorities spent US$250 million to rebuild much of the Skyway. As a result of a yearly increase in tolls, the current rate for passenger cars and other two axle vehicles is $3.50, with higher rates for vehicles with more axles. A discount is given during the overnight hours for vehicles with three or more axles. This 50 cent increase went into effect on January 1, 2011.
