Construction of the Eastern Expressway, a limited-access highway connecting the Inner Loop to the Thruway in Victor, began in the early 1950s with the first section extending from NY 96 in Bushnell's Basin to NY 31F near East Rochester. It was completed by 1956 and originally designated as part of NY 96. An extension northwest to the present site of the Can of Worms was opened to traffic by the following year. The expressway remained part of NY 96 until when it was designated as part of I-490, a proposed route extending westward through downtown Rochester and southwestward through the western suburbs to Thruway exit 47 in Le Roy. The portion of the highway between the Inner Loop and Winton Road was completed in the old subway cut by this time, while the segment between Winton Road and the Can of Worms was opened .
