Interstate 90 (I-90) was first authorized in 1956 as part of the Interstate Highway System, which aimed to create a network of highways across the United States. Construction began shortly thereafter, with various segments opening over the following years. The entire route, stretching from Seattle, Washington, to Boston, Massachusetts, was completed in 1992.
The longest Interstate Highway is I-90, running from Boston MA to Seatle WA with about 3100 miles.. The second longest Interstate highway is I-80, running from San Francisco CA to New York NY with about 2900 miles.
The last interstate highway was completed in 1993 in Los Angeles. The Century Freeway, Interstate 105, was completed after 37 years of construction. The route connects Los Angeles International Airport with Interstates 405, 110, 710, and 605.
The first four-lane highway in the United States is widely considered to be the Pennsylvania Turnpike, which opened in 1940. This highway featured multiple lanes in both directions, setting a precedent for future interstate roadways. The design aimed to improve safety and reduce travel time, paving the way for the development of the Interstate Highway System in the following decades.
