In the early 1950s, construction began on the Sea Breeze Expressway, a mostly limited-access highway linking the Lake Ontario shoreline to the proposed I-490 east of Rochester. The first portion of the road, a divided highway extending from East Ridge Road in Irondequoit to Culver Road just west of the Irondequoit Bay Outlet, was opened to traffic by 1954 as a realignment of NY 18. Construction on a limited-access extension south to Empire Boulevard (three blocks west of NY 47's western terminus) began at some point between 1956 and 1958 and was completed by 1960 as a realignment of US 104. Another extension of the highway south to the partially complete I-490 in Brighton was completed and largely became part of a rerouted NY 47 by the following year. At the time, NY 47 left the expressway at Blossom Road and followed it west to Winton Road, where it rejoined its original routing.
