About New York State Route 311 in brief

Summary New York State Route 311New York State Route 311 is a state highway in Putnam County, New York. The highway begins at NY 52 in Lake Carmel, and intersects Interstate 84 shortly thereafter. It crosses the East Branch Croton River at the north end of the wetland area known as the Great Swamp. Part of modern-day NY 311 was once part of the Philipstown Turnpike, a road built in 1815 to overcome a lack of transportation when the Hudson River froze during the winter months. In the 1930 renumbering of state highways in New York, the segment of former NY 39 east of West Patterson was renumbered to NY  311. A number of historic sites are located on the route, including the Patterson Presbyterian Church, the Fellowship Hall, Christ Episcopal Church, and the Maple Avenue Cemetery and the Grange Hall.

The road terminates at a junction known as Akins Corners, just south of the Dutchess County line. It is one of the few large bodies of water in putnam County not used as a reservoir by New York City. The Great Swamp is the second largest wetland in the state, extending as far north as Dover in Dutchetss County. It was created by developers in the early 20th century by damming the Middle Branch of the Croton river. The lake has a surface area of about 200 acres, and it sits at 618 feet in elevation. The route passes several historical sites, including a church and the Patterson Fire Department, which is located along the route. It parallels the Putnam–Dutcheess county line east into the hamlet of Patterson, serving as the main street of the community.
