New York State Route 30 (NY 30) is a state highway in the central part of New York in the United States. It extends for 300.71 miles (483.95 km) from an interchange with NY 17 in the Southern Tier to the US–Canada border in the state's North Country, where it continues into Quebec as Route 138. On a regional level, the route serves to connect the Catskill Park to the Adirondack Park. In the latter, NY 30 is known as the Adirondack Trail. Aside from the state parks, the route serves the city of Amsterdam and several villages.

New York State Route 206 (NY 206) is a 74.57-mile-long (120.01 km) state highway in the Southern Tier of New York in the United States. It runs through some lightly populated regions along the state's southern border, from Central New York to the Catskills. It begins near a busy intersection with Interstate 81 (I-81) at Whitney Point and runs east from there through Greene. The eastern terminus is located at a junction with NY 17 at Roscoe in Sullivan County. It is one of the longest three-digit routes in New York, and the only long one not associated with a two-digit route or a former U.S. Route. Yet due to its location it sees little traffic, although for much of its length it follows the route of a main 19th century thoroughfare, the Catskill Turnpike. It is primarily detour around Binghamton.
