extension of the Keeler Street Expressway, named the Irondequoit–Wayne County Expressway, opened between the Sea Breeze Expressway (at this point designated as part of NY 47) and Five Mile Line Road. In between, US 104 crossed Irondequoit Bay by way of the Irondequoit Bay Bridge. US 104's former surface alignment between NY 47 and Five Mile Line Road was redesignated NY 404 while US 104 was temporarily realigned onto Five Mile Line Road between the expressway and Ridge Road to connect to its former alignment. Redesignation and completion The segment of I-81 through central New York was built on an alignment that closely paralleled US 11 from the Pennsylvania state line northward to the city of Watertown. The portion of I-81 near Maple View was completed in late 1961, at which time US 104 was extended eastward over NY 126 to meet the new highway. NY 126 was truncated on its west end to the I-81 interchange as a result. US 104 was redesignated as NY 104 in June 1971, making the route the third to bear the NY 104 designation. As part of the change, NY 104 was extended east to NY 13, completely supplanting NY 126. By 1978, the frontage roads between Five Mile Line Road and NY 250 in Webster were completed. NY 104 was rerouted eastward along the roadways while NY 404 was extended over NY 104's old alignment to NY 250 in Webster. The section from NY 250 to the existing expressway at the Wayne County line was built in the late 1970s while the main carriageway of NY 104 between Five Mile Line Road and NY 250 was completed in the early 1980s. NY 404 was extended east along the former alignment of NY 104 to the county line upon the total completion of the Five Mile Line Road–NY 250 segment.
