context_page_description: Interstate 70 is a major east–west Interstate Highway in the United States that runs from I-15 near Cove Fort, Utah, to a Park and Ride lot just east of I-695 in Baltimore, Maryland. I-70 approximately traces the path of U.S. Route 40 east of the Rocky Mountains. West of the Rockies, the route of I-70 was derived from multiple sources. The Interstate runs through or near many major cities, including Denver, Kansas City, St. Louis, Indianapolis, Columbus, Pittsburgh, and Baltimore. The sections of the interstate in Missouri and Kansas have laid claim to be the first interstate in the United States. The Federal Highway Administration has claimed the section of I-70 through Glenwood Canyon, Colorado, completed in 1992, was the last piece of the Interstate Highway system, as originally planned, to open to traffic. The construction of I-70 in Colorado and Utah is considered an engineering marvel, as the route passes through the Eisenhower Tunnel, Glenwood Canyon, and the San Rafael Swell. The Eisenhower Tunnel is the highest point along the Interstate Highway system, with an elevation of 11,158 ft.
context_section_description: Besides being the first Interstate to receive a contract for pavement, other oddities happened with I-70 as well.
  As first proposed, the western terminus of I-70 was to be Denver. However, Utah and Colorado pressured the federal government to extend the planned freeway farther west, arguing a direct link between Denver and Salt Lake City was vital for an effective highway system. The proposal was to follow what is now US 6 west and connect to I-15 at Spanish Fork, Utah. Federal planners (influenced by the military) agreed to extend the proposed route of I-70, but not to serve Salt Lake City; the military wanted to better connect Southern California with the Northeast. This led to I-70's constructed route through the San Rafael Swell terminating at Cove Fort. Many motorists include I-70 as part of their cross-country drives between New York City and Los Angeles (which are accessible to I-70 via other Interstates).
  As a result of freeway revolts in the Baltimore area, I-70 was not completed east of MD 122 to its planned terminus at I-95 within the city of Baltimore, and it now ends at a four-way symmetrical stack interchange with I-695, the Baltimore Beltway. Until November 2014, I-70 ended at a Park and Ride lot at MD 122 as the freeway enters the city of Baltimore at exit 94. Commuters park on the pavement where high-speed freeway lanes were to be. The former freeway from I-695 to MD 122 is being converted into a two-lane parkway to be renamed Cooks Boulevard, maintained by the Maryland State Highway Administration.
  The highway gave its name to the I-70 Killer, a serial killer who committed a string of murders within a few miles of it in several Midwestern states in the early 1990s. No suspect has ever been apprehended despite the widespread publicity the murders generated, including their being featured several times on the television show America's Most Wanted and Unsolved Mysteries.
  John Allen Muhammad and Lee Boyd Malvo, the duo responsible for the Beltway sniper attacks, were apprehended at a rest stop on I-70 near Myersville, Maryland, in 2002.
  The 1985 World Series was a contest between the St. Louis Cardinals and the Kansas City Royals, and won by the Royals. As these cities are primarily connected by Interstate 70, the media often called series the I-70 Series.
