It rejoins I-90 in Albany County, where I-90 leaves the mainline of the Thruway at exit 24 in Albany, which is signed for I-87 north and I-90 east. Here, the route designation of the Thruway changes from I-90 east to I-87 south. Traffic intending to continue on I-90 or reach I-87 north must exit the Thruway here. Exit numbers and mile markers for I-90 reset after exiting.

(BPR) commissioner soon announced that the toll road met all federal Interstate Highway standards, and, on August 14, 1957, most of the mainline of the Thruway was incorporated into the system as part of I-87 and I-90. Most of the connecting

was also included, but a more northerly alignment, avoiding the Berkshire Thruway, was proposed by the states of New York and Massachusetts for I-90 through Albany past Pittsfield to East Lee, Massachusetts. This alignment would be about 30 percent shorter than the all-toll alignment and would provide relief to the four-lane Castleton Bridge on the Berkshire Thruway, which had been built narrower than the rest of the system because of the planned parallel alternate. The BPR objected to the duplication, which would cost over $90 million (equivalent to $ in ), and refused to approve this alignment. The eventual route ran southeast from Albany to the Berkshire Thruway at the Nassau interchange, providing Albany with an alternate route and additional bridge but not offering any savings in distance and creating a "toll trap" for drivers accessing the Taconic State Parkway from Albany. Construction on the route of I-90 through Albany began , with both ends at existing Thruway interchanges: exit 24, which crossed the Adirondack Northway (I-87) at a

Work on the freeway began at the Northway and progressed southeasterly to the Berkshire Connector in Rensselaer County. The portion between the Northway and Everett Road was opened to traffic in the mid-1960s while the piece extending from Everett Road to US 4 east of Rensselaer was completed in the early 1970s. The last section of the highway was completed to US 9 and US 20 in Schodack Center and finished by 1977. The Northway cloverleaf was rebuilt in the late 1980s. In 1999, the New York State Department of Transportation (NYSDOT), the

(FHWA), and NYSTA discussed redesignating the

as I-90 and redesignating the non-toll part of I-90 from Thruway exit 24 to exit B1 on the connector as I-88. The section of the Thruway between exits 25 and 24 would then be codesignated as both I-90 and I-88. This was never implemented.
