Highway in Vermont, USA
Vermont Route 22A (VT 22A) is a 44.738-mile-long (71.999 km) state highway in western Vermont, United States. It is the northward continuation of New York State Route 22A. Its southern end is at the New York state line in Fair Haven and its northern end is in Ferrisburgh at U.S. Route 7 (US 7). As it is an extension of NY 22A, VT 22A is a spur route of NY 22, which runs roughly parallel to VT 22A west of the state border. This is a rather unusual case of one state having a suffixed route of another state's primary route. Vermont does not currently have a "Route 22."
All of VT 22A north of Fair Haven was originally designated as Route 30A, a highway in the New England road marking system, in 1922. Route 30A was added to the Vermont state highway system in 1935 as Vermont Route 30A. An extension south to the New York state line was added to the route later in the decade. VT 30A was renumbered to VT 22A on December 19, 1945 when New York renumbered the continuation across the state line.
