I-90 crosses the Continental Divide over what Pass in the Rocky Mountains of Montana?
Interstate 90 Interstate 90 (I-90) is a transcontinental freeway, and the longest Interstate Highway in the United States at 3,020.54 mi . Its western terminus is in Seattle, at State Route 519 near Safeco Field and CenturyLink Field, and its eastern terminus is in Boston, at Route 1A near Logan International Airport. I-90 crosses the Continental Divide over Homestake Pass just east of Butte, Montana. East of the Wisconsin-Illinois border, much of I-90 follows several toll roads, many of which predate the Interstate Highway system. The Jane Addams Memorial Tollway, Chicago Skyway, Indiana Toll Road, Ohio Turnpike, New York State Thruway, Massachusetts Turnpike, and the Ted Williams Tunnel are all toll roads used by I-90 in the eastern half of the country. The Interstate is not tolled through some segments in downtown Chicago; Greater Cleveland, and the rest of Northeast Ohio; Pennsylvania; and through brief sections near Buffalo and Albany. Erie, Pennsylvania; Madison, Wisconsin; Billings, Montana; and Spokane, Washington are other major cities on I-90.
Medicine Bow Mountains The Medicine Bow Mountains are a mountain range in the Rocky Mountains that extend for 100 mi from northern Colorado into southern Wyoming. The northern extent of this range is the sub-range the Snowy Range. From the northern end of Colorado's Never Summer Mountains, the Medicine Bow mountains extend north from Cameron Pass along the border between Larimer and Jackson counties in Colorado and northward into south central Wyoming. In Wyoming, the range sits west of Laramie, in Albany and Carbon counties to the route of the Union Pacific Railroad and U.S. Interstate 80. The mountains often serve as a symbol for the city of Laramie. The range is home to Snowy Range Ski Area.
