U.S. Route 92 or U.S. Highway 92 is a 181-mile (291 km.) U.S. Route entirely in the U.S. state of Florida. The western terminus is at US 19 Alt. and SR 687 in downtown St. Petersburg. The eastern terminus is at SR A1A in Daytona Beach.
Interstate 687 (I-687) was a proposed auxiliary Interstate Highway in the Capital District region of New York in the United States. The highway would have connected I-90 in to I-87 and Albany International Airport in Colonie. I-687 faced opposition from those living in the path of the highway, and ultimately all that was built of the highway was its interchange with I-90 in Albany, which now connects to a surface road, Corporate Woods Boulevard. The project was canceled in 1973, and I-687 was removed from the Interstate Highway System four years later. A small portion of what would have been I-687 is now used as a connector between the Adirondack Northway and Albany International Airport; it, however, does not have a route designation and was completed as its own separate project in November 2019.
