New York State Route 347
New York State Route 347 (NY 347) is an east–west state highway located in Suffolk County, New York, in the United States. It connects the Northern State Parkway in Hauppauge to NY 25A in Mount Sinai. The route serves as a southern bypass of Smithtown and as a direct link between Nesconset and Port Jefferson, leading to the road being known as Smithtown Bypass in the Town of Smithtown, and for its entire length as the Nesconset–Port Jefferson Highway. Along the way, NY 347 intersects NY 25 in Nesconset and Nicolls Road (County Route 97 or CR 97) in Lake Grove. The westernmost 2 miles (3.2 km) of NY 347 is concurrent with NY 454 while the portion northeast of NY 25 parallels NY 25A, which follows a more northerly alignment through the Town of Brookhaven than NY 347.
The highway was built by Suffolk County in the 1950s and designated as part of two county routes. It gained a single designation in 1966 when the state of New York assumed ownership and maintenance of the highway and designated it as NY 347. Several proposals to extend or improve the highway have been developed in the years since; however, none have been implemented, mostly due to community opposition.
NY 347 begins at an interchange with NY 454 and the Northern State Parkway in Hauppauge; this interchange also serves as the eastern terminus of the Northern State Parkway. Proceeding eastbound, NY 347 and NY 454 are immediately concurrent on Veterans Highway, crossing as a six-lane arterial road through the town of Smithtown, passing south of Blydenburgh County Park. Forestwood Park soon begins nearby, while the two routes continue eastward before the two routes fork at an interchange in Smithtown. NY 347 bends to the northeast on Smithtown Bypass, intersecting with County Route 76 (CR 76; Townline Road). The route proceeds northeastward as a four-lane commercial arterial, crossing an at-grade interchange with NY 111 (Hauppauge Road).
NY 347 continues northeast as Smithtown Bypass, entering the Nesconset section of Smithtown. In Nesconset, NY 347 becomes a four-lane wooded arterial before passing east of Village of the Branch, where homes surrounded the highway from connecting roads. The route becomes commercial once again, NY 347 intersecting with CR 16 (Terry Road). The route bends to the east, crossing through Nesconset, then to the northeast and enters an at-grade interchange with NY 25 (Middle Country Road). Crossing into the Saint James section of Smithtown, NY 347 continues to the northeast as the four-lane commercial arterial, now known as Nesconset Highway. NY 347 soon leaves Smithtown for Lake Grove, where it expands to six lanes, crossing a short time into Brookhaven before re-entering Lake Grove. In the second entrance of Lake Grove, NY 347 intersects with CR 97 (Nicolls Road), which continues south as an eight-lane limited-access highway.
NY 347 continues to the northeast into the Town of Brookhaven once again, passing north of Percy B. Raynor Memorial Park. Crossing power lines, the route enters the hamlet of Terryville, and soon into Port Jefferson Station, where it intersects with NY 112 (Patchogue Road). After passing near the yard for the Port Jefferson Branch of the Long Island Rail Road before merging into the right-of-way with NY 25A (Hallock Avenue) in Mount Sinai.
What is now NY 347 was originally built by Suffolk County in the 1950s as two separate highways, along a former dairy farmer delivery route. Southwest of NY 25, it was known as Smithtown Bypass and designated as CR 85. Northeast of NY 25, it was named the Nesconset–Port Jefferson Highway and designated as CR 80. Although the road acts as an eastward extension of the Northern State Parkway (with a 2-mile or 3.2-kilometre section of Veterans Memorial Highway, now NY 454, connecting the two), Robert Moses planned an altogether different right-of-way for an extension of the Northern State. In fact, the Parkway was planned to have an interchange with Smithtown Bypass west of CR 16 (Terry Road).
In 1966, the state of New York acquired both CR 80 and CR 85 and designated the new, unified route as NY 347. Suffolk County hoped that by transferring jurisdiction to the state, it would be easier to upgrade the road into the limited-access highway as was originally intended. The CR 80 and CR 85 designations were later reused for portions of Montauk Highway, then part of NY 27A, that were transferred from the state to the county. CR 80 was reassigned to the portion of Montauk Highway between Patchogue and Hampton Bays on October 6, 1966, while CR 85 was given to the section between Oakdale and Patchogue on March 29, 1972.
In 1973, NYSDOT tried once again to transform NY 347 into a freeway; the proposal also included the widening of NY 25 west of NY 347 and the addition of frontage roads along NY 25. This, too, was cancelled by community opposition – as were subsequent, revived plans to upgrade the road between 1987 and 1988. In 1991, after an extensive study considering numerous alternative plans for rebuilding Nesconset Highway, NYSDOT selected "Alternative 12a" as its preferred option. This option retained the limited-access features of a freeway while limiting the use of frontage roads to those areas which truly needed them. The footprint of this option was kept to a minimum through the use of single-point urban interchanges rather than complex and expansive cloverleaf-type interchanges. Plans for building this option were ultimately shelved.
