Nassau Expressway (NY 878)

The Nassau Expressway, designated NY 878, is a short but strategically important state highway with two disconnected sections in southern Queens and western Nassau County. Closely tied to Rockaway Boulevard, North Conduit Avenue, and the Belt Parkway corridor, the route serves as a major access road for John F. Kennedy International Airport while also carrying everyday commuter and commercial traffic through Inwood, Lawrence, Cedarhurst, and the broader Five Towns area. Although the road was once planned as part of a longer east–west expressway, only portions of that original vision were built.
History
- Initial Planning: The Nassau Expressway was conceived in the mid-20th century as part of a broader regional highway network intended to improve east–west travel between southern Queens and Nassau County.
- Phased Construction: Segments were developed over time, with the airport-adjacent Queens section emerging as the most clearly expressway-style portion of the route.
- Unbuilt Extensions: Much of the larger plan was never completed, a common outcome for proposed New York-area expressways affected by changing priorities, local opposition, environmental concerns, and funding limits.
- Current Form: Today, NY 878 is best understood as a split route: a limited-access highway section near JFK Airport and a separate at-grade arterial segment serving western Nassau County.
Route and Significance
- Queens Expressway Section: The western section functions as a limited-access connector in the JFK area, linking airport approaches with the Belt Parkway, the Van Wyck Expressway (I-678), Rockaway Boulevard, and nearby local roadways.
- Nassau Surface Section: In Nassau County, NY 878 generally follows the Rockaway Turnpike/Nassau Expressway corridor through Inwood, Lawrence, Cedarhurst and adjacent communities toward the Valley Stream area.
- Length: The two signed sections together total roughly 10 miles, though exact mileage references can vary slightly by source.
- Regional Role: The route is important not only for airport access, but also for freight movement and daily east–west travel in a densely developed part of western Nassau County.
- Travel Pattern: Congestion is common during rush hours, school travel periods, and peak flight times, so checking traffic conditions ahead of time is a good idea.
Key Interchanges and Connections
| Connection | Destinations / Notes |
|---|---|
| Belt Parkway / Van Wyck Expressway (I-678) | Major regional links for traffic heading toward Brooklyn, Staten Island, the Bronx, and the broader New York City expressway network. |
| Rockaway Boulevard | Provides access to South Ozone Park, airport-adjacent businesses, cargo areas, and local streets near JFK. |
| North Conduit Avenue | Useful for Howard Beach and nearby local access routes that parallel parts of the airport corridor. |
| JFK Airport Roadways | Signs direct drivers toward terminals, parking, rental car facilities, and airport service roads. Terminal access patterns may change, so follow current posted signage. |
Notable Facts
- NY 878 is unusual because it exists as two separate signed sections rather than one continuous highway.
- The route remains one of the more important non-parkway corridors in the area, making it especially useful for trucks and other vehicles restricted from parkways.
- In western Nassau County, the corridor is a major east–west route for the Five Towns and nearby neighborhoods, so backups can develop quickly.
- Near JFK, traffic patterns can shift with airport construction, terminal road changes, and security-related roadway adjustments.

The Nassau Expressway (NY 878) is short and incomplete by original planning standards, but it remains a highly practical road for drivers moving between JFK Airport, southern Queens, and western Nassau County. For travelers, commuters, and commercial traffic alike, it continues to provide an important alternative to nearby parkways and local streets. Because airport access patterns, construction activity, and traffic volumes can change, it is wise to check current conditions before heading out and to follow posted signs once you are on the road.
