Unused highway

  (Redirected from Stub road)

An unused highway is a highway or highway ramp that was partially or fully constructed, but went unused or was later closed. An unused roadway or ramp may often be referred to as an abandoned road, ghost road, highway to nowhere, stub ramp, ghost ramp, ski jump, stub street, stub-out, or simply stub.[2]

An unused section of divided highway approaching Interstate 189 in Burlington, Vermont (looking southward from: 44°26′57″N 73°13′3″W / 44.44917°N 73.21750°W / 44.44917; -73.21750); some lanes are now blocked by discarded electronics.
The 1956 span of the Gandy Bridge between Tampa and St. Petersburg was closed to traffic in 1997 and used as a recreational trail from 1999 until 2008, when it was closed for safety reasons. It remained in place as officials decided between demolition or renovation. In 2015, demolition of the unused bridge began.

Some examples of reasons for unused highways include:

  • An older portion of roadway being left unused by a highway realignment. The Abandoned Pennsylvania Turnpike is one instance of this, where two 2-lane tunnels and 4-lane approaches were bypassed with 4-lane cuts. The old tunnels and approach roadways in this case are being rehabilitated for a multi-use trail. Some parts of the A1 and A3 motorways in Italy have been recently abandoned after some dangerous, curvy and narrow mountain stretches were replaced by wider and straighter alignments through new viaducts and tunnels. In many roads in the Alps, some dangerous sections were replaced by tunnels and the abandoned parts are usually closed to traffic and used as hiking trails.
  • A road which existed to serve a bridge becomes a dead-end once the bridge is demolished or left to deteriorate to the point where it can no longer be safely used. This is common on some older alignments of U.S. Route 66 which were bypassed, as the route was changed through multiple realignments before becoming a decommissioned highway in 1985.
  • A road becomes a dead end once a level railway crossing is closed and replaced by an overpass/underpass some distance away from the former level crossing (common in Greece).
  • A highway being closed and demolished, where stubs remain on intersecting roads. Examples include ramps from the Embarcadero Freeway that remained on the Bay Bridge approach (Interstate 80) in San Francisco after the demolition of the Embarcadero Freeway proper. The remaining ramps were demolished in 2010–11 during demolition of the old Transbay Terminal to make way for the new Transbay Transit Center.
  • Highway construction begins but is cancelled, possibly because of a freeway revolt. Examples include:
  • Stubs are built to connect to a highway that is not yet constructed. These stubs are very common in the state of North Carolina, where they will eventually connect to new stretches of I-73, I-74, and I-840, among others, along the Greensboro Urban Loop. Remnants of stub ramps can be seen on the Massachusetts Turnpike in West Stockbridge. The ramps were used to connect the newly built highway, completed in May 1957, with local roads prior to the connection with the New York State Thruway, completed to the NY-MA state line in May 1959.[8] Also, in Melbourne, Florida, the westernmost point of Pineda Causeway will eventually connect to Wickham Road, but for the meantime, it has been blocked westward of the I-95 ramp.
  • A part of the highway can become unused due to changes in national borders. Some stretches of the Berlin–Königsberg autobahn are unused after the partition of East Prussia because the highway lacks a border crossing between Poland and Russia. Some small roads between different European countries didn't have border crossing facilities and were closed to traffic until those countries joined the Schengen Agreement. Some border roads are closed when the two countries have bad relations or are at war with each other, for example between Algeria-Morocco, North Korea-South Korea, Israel-Lebanon, Israel-Syria, Turkey-Armenia, and Azerbaijan-Armenia.
  • The highway is used for a purpose different from what was originally intended. The east end of I-70 in Baltimore[9] and the stub of I-95 inside the Capital Beltway northeast of Washington, DC, are two examples because of the cancellations of their alignments within the inner city. Both of these stubs are used for park-and-ride facilities. In England, improvement works in 1987 rerouted the A47 in Rutland near Wardley, resulting in an unused stretch of carriageway that was left behind, which functions only as access to a transmitting station.[10] Part of the A2 in Kent was realigned in 2009, leaving a substantial part of the original road intact. Part of the road has been made into a public park. On I-90 near Albany, New York, an interchange was built for the never-to-be I-687; that interchange (labeled as exit 5A off I-90) now serves as an exit for Corporate Woods Boulevard. The exit ramps occupy nearly as much space as the area they serve.[11]
  • The highway has unused lanes. The 1000 Islands Parkway contains two "ghost lanes" for its entire 40 kilometres (25 mi) length. Its right-of-way is four-lane divided, as it was part of Highway 401, Canada's busiest highway, during that freeway's construction. When Highway 401 was ultimately completed in 1968, the final 1000 Islands bypass took a path further inland. Two lanes of the original four-lane waterfront right-of-way were retained and used for the scenic parkway, the rest becoming small pedestrian or bicycle trails laid out in an otherwise-vacant freeway-grade right-of-way.
