Interstate 90 Traffic Cameras: I-90 Live Views Coast to Coast

Interstate 90 stretches 3,020 miles from Seattle, Washington to Boston, Massachusetts, making it the longest interstate highway in the United States. The corridor handles immense volumes; a section of I-90 in Chicago reaches an Average Annual Daily Traffic (AADT) of 321,700, while profiles in other major metros show volumes up to 350,000 vehicles. According to the FHWA, real-time traffic monitoring helps drivers make safer, more informed decisions. Research indicates that real-time traveler information systems can reduce incident-related delays by up to 40% by providing drivers with the intelligence needed to find alternate routes. Every camera is plotted on an interactive map — zoom, search, and click to view any location instantly.
