In New York, it was overlaid on the preexisting New York State Thruway from Pennsylvania to Albany, from where it would have continued to Massachusetts on a new freeway that bypassed the Berkshire Connector to the north. Ultimately, the freeway was built from the Thruway mainline in Albany to the Berkshire Connector in Schodack, and I-90 was assigned to the segment of the connector east of the proposed freeway. The Albany–Schodack freeway was completed in stages during the 1960s and 1970s and fully open by 1977.
