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.
