I-90 would use several expressways and tollways in the Chicago area, the earliest of which was the Tri-State Expressway (now the Kingery Expressway), completed in 1950 and extended into Indiana the following year. It was followed by the

in Chicago.
The other tolled sections of I-90 were completed in the 1950s by their respective state governments. The Ohio Turnpike opened to traffic on October 1, 1955, three years after construction began. The first segment of the New York Thruway opened in June 1954 and was followed by extensions to Buffalo and the Albany area by the end of the year. It was extended to the Pennsylvania state line in 1957 and to the Massachusetts Turnpike via the Berkshire Connector in 1959. The Berkshire section linked with the Massachusetts Turnpike, which had opened in 1957 from the state line to Newton, a distance of .

Non-tolled construction
The freeway also incorporated other non-tolled expressway bypasses planned by state governments in the early 1950s and modified to meet Interstate standards. A bypass of Spokane Valley, Washington, opened in November 1956 as the first section in Washington and was extended into neighboring Spokane two years later. Wisconsin opened their first section in November 1959, connecting the terminus of the Illinois Tollway with Janesville, and extended the freeway through the Madison area to Wisconsin Dells in 1962. The Cleveland Innerbelt opened in stages from 1959 to 1962 and was originally planned to connect with the Parma Freeway, which would have carried I-90 around the northwest side of Downtown Cleveland. It was later cancelled in the 1960s amid

. The first Minnesota section, built to bypass Austin, began construction in 1957 and opened in 1961.
Wisconsin was among the first states to complete its rural Interstate system and opened its final section of I-90, from La Crosse to Tomah, in November 1969. The section around Albany, New York, built as a toll-free alternative to the New York Thruway, was completed in 1976 with a connection to the Berkshire Connector, which had been originally intended to carry the I-90 designation across the Hudson River. South Dakota completed its final section in November 1976, which created an unbroken stretch of four-lane highway from the Wyoming state line to Boston but some intersections remained. The Minnesota segment of I-90 was declared complete in September 1978 with a dedication at Blue Earth, where a golden line was painted to emulate the

The western states were the last to complete their segments of I-90. Wyoming opened its final section, from the Montana state line to Sheridan, in July 1985 and dedicated it three months later following the completion of Montana's cross-border section. The last two-lane section in Montana, near Springdale, was widened to four lanes in May 1987. One of the last rural sections of I-90 to be built was through

Completion and later projects
Washington was the last state to complete its section of I-90, primarily due to disputes and litigation over the Seattle–Bellevue section. The Snoqualmie Pass section was completed in 1981 with a viaduct for westbound traffic that stands over Denny Creek. The viaduct replaced an earlier plan for a ground-level freeway at the behest of environmentalists; the

The extension into Seattle was completed in stages between 1989 and 1993 and cost $1.56 billion (equivalent to $ in dollars) to construct. The project involved construction of a new floating bridge, expansion of the Mount Baker Ridge Tunnel, addition of lids with parks, and extensive mitigation for environmental and social impacts. The project was originally planned to be completed in 1992, but was delayed a year due to the sinking of the original floating bridge during renovations in November 1990; the bridge was rebuilt and opened for eastbound traffic on September 12, 1993.
Extensions at both termini of I-90 were completed in the early 2000s as part of separate projects. The west end at Washington State Route 519 in Seattle was rebuilt as a series of ramps near

megaproject in Boston that extended I-90 east by under Fort Point Channel and Boston Harbor to Logan International Airport opened on January 18, 2003, at a cost of $6.5 billion (equivalent to $ in dollars). The Fort Point Channel tunnel later closed in July 2006 due to a ceiling panel collapse that killed one person. It reopened in January 2007 after repairs and retrofit work.
Other sections of I-90 have been rebuilt or replaced to accommodate modern needs and meet updated safety standards. The Dan Ryan Expressway in Chicago was reconstructed over a two-year period from 2006 to 2007 at a cost of $975 million (equivalent to $ in dollars), adding auxiliary lanes and improved bridges. The section carried over 300,000 daily vehicles prior to the project. Cleveland's

The old bridge was imploded with explosives on July 12, 2014, and dismantled by the end of the year. The states of Minnesota and Wisconsin replaced the Dresbach Bridge over the Mississippi River in 2016; the project was spearheaded by Minnesota following the I-35W Mississippi River bridge collapse in 2007.
