In the 1960s, the portion of Browncroft Boulevard from the Sea Breeze Expressway to Blossom Road was upgraded into a divided highway.

It heads east through residential surroundings as a four-lane highway, proceeding through the remainder of NY 590 exit 7 as it enters the northernmost portion of the town of Brighton.

It passes into Penfield upon crossing Irondequoit Creek and curves southeast as it straddles the northern boundary of Ellison Park.

[3] The two highways loosely parallel each other southeastward for 0.75 miles (1.21 km) to White Village Drive, a residential side street branching off Browncroft Boulevard.

NY 286 continues eastward, leaving the Ellison Park area and intersecting Blossom Road.

[4] In the 1930 renumbering of state highways in New York, NY 35 was extended northeast from Canawaugus (west of the village of Avon) to Ontario by way of Scottsville, Rochester, and Walworth.

NY 35 entered Rochester on Scottsville Road and followed Genesee and Main streets through the city.

[2][10] The portion of the Sea Breeze Expressway between Empire Boulevard (at the time U.S. Route 104 and now NY 404) and Interstate 490 opened to traffic c. 1961.

A new roadway was constructed during the mid-1960s that directly connected the two portions of Atlantic Avenue and bypassed County Line Road entirely and became part of a realigned NY 286 by 1968.

[13][14] Browncroft Boulevard was upgraded into a four-lane divided highway between the Sea Breeze Expressway (NY 47) and Blossom Road during the mid-1960s.
