context_page_description: Interstate 90 is an east–west transcontinental freeway, and the longest Interstate Highway in the United States at 3,020.54 miles. Its western terminus is in Seattle, at State Route 519 near T-Mobile Park and CenturyLink Field, and its eastern terminus is in Boston, at Route 1A near Logan International Airport.
  The western portion of I-90 crosses the Continental Divide over Homestake Pass just east of Butte, Montana, connecting major cities such as Spokane, Washington; Billings, Montana; Sioux Falls, South Dakota; and Madison, Wisconsin.
  Between Seattle and the Wisconsin-Illinois state line, I-90 is an Interstate without tolls. East of that border, much of I-90 follows several toll roads, many of which predate the Interstate Highway system. These include the Jane Addams Memorial Tollway, Chicago Skyway, Indiana Toll Road, Ohio Turnpike, New York State Thruway, and the Massachusetts Turnpike. The Interstate is not tolled through some segments in downtown Chicago; Greater Cleveland and the rest of Northeast Ohio; Erie and the rest of Northwestern Pennsylvania; and through brief sections near Buffalo and Albany.
context_section_description: I-90 in Massachusetts runs concurrently with the pre-Interstate-era Massachusetts Turnpike (known locally as "the Pike" or on signs as "MassPike"), which opened on May 15, 1957, from West Stockbridge at the New York state border to Route 128.
  The first section of the Boston Extension opened in September 1964 from the original Massachusetts Turnpike eastern terminus at Route 128 to the Allston/Brighton Tolls. The entire Boston Extension opened on February 18, 1965 continuing from the Allston/Brighton Tolls to I-93 in Downtown Boston. The new extension added 12 miles (19 km) to the MassPike's original 123.
  I-90 was extended again as part of the Big Dig from its terminus at I-93 to Boston's Logan International Airport and a terminus of Route 1A in January 2003 via tunnels under the Fort Point Channel and the Ted Williams Tunnel under Boston Harbor. This extended I-90 by an additional 2.3 miles (3.7 km), before finally terminating at Route 1A.
  Tractors with two 48-foot (15 m) trailers, called "turnpike doubles", are permitted to travel between exit 11 and through the New York state border.
