Seaford–Oyster Bay Expressway (NY 135)
The Seaford–Oyster Bay Expressway (NY-135) is a limited-access north–south expressway running through central Nassau County, Long Island. Stretching approximately 15 miles, it connects the South Shore community of Seaford to Jericho and Syosset on the North Shore.
Opened between 1959 and 1962, NY-135 was originally planned to extend north across Long Island Sound as part of the proposed Oyster Bay–Rye Bridge, a project later canceled in the 1970s. The expressway today remains a vital commuter route linking Sunrise Highway (NY-27), Southern State Parkway, Bethpage State Park, Northern State Parkway, and Jericho Turnpike (NY-25).
