NY 111 and NY 347 South Jug Handle Intersection in Hauppauge — Live Traffic Webcam

NY 111 and NY 347 Intersection: Central Long Island Transportation Hub

The intersection of NY 347 and NY 111 in Hauppauge is one of those intersections that rarely make it into tourist guidebooks but handle thousands of vehicles every day. This at-grade signalized intersection sits in the heart of Suffolk County on Long Island and serves as a key junction for drivers traveling between the island's north and south shores. The live webcam captures traffic in real time, allowing you to assess the congestion at this strategic intersection.

NY 347: From Smithtown Bypass to Nesconset Highway

Route NY 347 begins at the interchange with NY 454 and Northern State Parkway in Hauppauge — the same interchange serves as the eastern terminus of Northern State Parkway. The road diverges from Veterans Highway and heads east as the Smithtown Bypass, providing a route around residential neighborhoods and connecting several communities in Suffolk County. In 1965, the New York State Department of Public Works proposed the construction of a so-called "Hauppauge Spur" — a branch from the southwestern end of Smithtown Bypass to the Long Island Expressway (I-495) in Hauppauge. This project was never realized, but the road itself remained an important transportation artery.

In 1973, NYSDOT officially removed the North Shore Expressway (NY 347) from its list of priority projects, although the Tri-State Regional Planning Commission continued to advocate for its construction. Nevertheless, the route retained its significance as a surface highway connecting several major population centers.

NY 111: Historic Route South from Hauppauge

New York State Route 111 crosses NY 347 in Hauppauge and continues south toward the hamlet of Islip. On September 13, 1966, the State Department of Public Works realigned NY 111 south of Hauppauge to follow a slightly more western route along Joshua's Path and Islip Avenue. This reconstruction gave the road its modern configuration and improved capacity on the approach to the intersection with NY 347.

Reconstruction Project: Decongesting and Going Green

In 2013, Governor Cuomo announced the start of a $25.6 million road reconstruction project in Suffolk County. The project, titled "Decongesting & Going Green," covered NY 347, NY 111, NY 25, and 12 side streets. GPI played a key role in designing this large-scale infrastructure upgrade.

The reconstruction aimed to relieve congestion and improve driver safety. The project included a comprehensive road reconstruction and widening, including intersection upgrades, updated road markings, and installation of new signal equipment. NYSDOT also considered building grade-separated interchanges at the NY 347 crossing with Nicolls Road (Suffolk CR 97) in South Setauket to increase capacity.

Pocket Park and Pedestrian Infrastructure

One of the distinctive features of the intersection is the pocket park in the southeastern quadrant — green gates and a rest area for the local community. This small park also serves as a stop for bicyclists and pedestrians crossing the busy intersection. An off-road shared-use path has been built on the south side of NY 347, providing safe passage for non-motorized road users.

Water mains run through the intersection area — 12", 8", and 6" pipes from NY 111 to Sequioa Ave — which under the Design-Build project could be relocated to the south side of NY 347. These engineering utilities highlight the complexity of the infrastructure hidden beneath the surface of this seemingly ordinary intersection.

Transportation Significance of the Intersection

The intersection of NY 111 and NY 347 is a key junction for drivers traveling through central Suffolk County. NY 347 and NY 454 compete with each other on Veterans Highway for a couple of miles after the interchange with Northern State Parkway, which adds extra load on the intersection. For residents of the North Shore and all of Long Island, this intersection provides critical connectivity between different areas.

NYSDOT documents on crash analysis and intersection capacity confirm its status as a high-risk zone with heavy traffic loads. The reconstruction project was largely motivated by the need to reduce accidents and improve traffic flow at this busy location.

Hauppauge: Location Context

Hauppauge is a hamlet in Suffolk County, located approximately 50 miles east of Manhattan. It is one of the largest commercial and industrial areas on Long Island, home to office parks, shopping centers, and manufacturing facilities. The high concentration of jobs makes Hauppauge's transportation infrastructure critical to the entire island's economy. The NY 111 and NY 347 intersection is in close proximity to major business districts, which explains its heavy congestion during peak hours.

What the Camera Shows

The webcam at the intersection of NY 111 and NY 347 South Jug Handle captures a signalized intersection with multiple travel lanes and road markings, including a crosswalk and divider lines. Vehicles travel along the road, with trees and vegetation visible along the edges. A traffic light on the right regulates the flow. The image includes text information about the camera (Camera 221 CR 83 @ RT 112). The camera captures real-time traffic at the intersection of these major highways, allowing you to assess current conditions at one of the key intersections in central Suffolk County.
