In the 1950s, NY 96 was temporarily moved onto the Eastern Expressway as sections of the freeway opened to traffic. The first section extended from Bushnell's Basin to NY 31F and opened to traffic in November 1955, at which time NY 96 was routed onto the new highway and NY 252 and NY 64 were extended eastward and northward, respectively, to cover NY 96's old surface alignment. NY 31F, meanwhile, was truncated to begin at the expressway. A northwest extension to what is now the Can of Worms was completed as a realignment of NY 96, resulting in the re-extension of NY 31F to its original terminus and an extension of NY 64 along East Avenue to the eastern edge of Rochester. NY 64, NY 96, and NY 252 were restored to their pre-1950s alignments when the freeway was designated as I-490.
