Please answer the following question: Information: - Interstate 264 ( abbreviated I - 264 ) is an Interstate Highway in the U.S. state of Virginia . It runs from a junction with Interstate 64 and Interstate 664 ( Hampton Roads Beltway ) near Bowers Hill in Chesapeake east into Portsmouth and through the Downtown Tunnel under the South Branch Elizabeth River into Norfolk . At the Interstate 464 interchange in the Berkley section of Norfolk , I - 264 turns north , crossing the East Branch Elizabeth River into downtown Norfolk on the Berkley Bridge , one of a small number of drawbridges on the Interstate Highway System . I - 264 then heads east through Norfolk , crossing Interstate 64 at the east side of the Hampton Roads Beltway , and into Virginia Beach , where it ends at Parks Avenue just short of the Atlantic Ocean . From this point , 21st and 22nd streets continue as a one - way pair with no route designation to U.S. Route 60 ( Pacific Avenue ) . The original section of I - 264 , designated in the late 1950s , lies between the two I - 64 junctions . The piece east to the Virginia Beach waterfront was built as the Virginia Beach - Norfolk Expressway ( a toll road until 1995 ) , and carried State Route 44 until I - 264 was extended over it in 1999 . When I - 64 was augmented in the 1990s with reversible HOV lanes , I - 264 towards Virginia Beach ( then SR 44 ) was designated as the eastern terminus of the reversible lanes and one of the few direct exits from / entrances to the HOV lanes . I - 264 is a part of the National Highway System for its entire length . A toll for use of the Downtown Tunnel began February 1 , 2014 . Tolls are collected electronically and ( as of 2015 ) set at $ 1.25 during peak hours and $ 1.00 during off - peak hours for E-ZPass users . - The Virginia Department of Transportation (VDOT) is the agency of state government responsible for transportation in the state of Virginia in the United States. Headquartered at the Virginia Department of Highways Building in Downtown Richmond, VDOT is responsible for building, maintaining, and operating the roads, bridges and tunnels in the commonwealth. It is overseen by the Commonwealth Transportation Board, which has the power to fund airports, seaports, rail and public transportation. - Open road tolling (ORT) or free-flow tolling is the collection of tolls on toll roads without the use of toll booths. An electronic toll collection system is usually used instead. The major advantage to ORT is that users are able to drive through the toll plaza at highway speeds without having to slow down to pay the toll. In some installations, ORT may also reduce congestion at the plazas by allowing more vehicles per hour/per lane. The disadvantage to ORT is the possibility of "leakage"; that is, "violators" who do not pay. Leakage may either be written off as an expense by the toll operator, or offset in part or whole by fees and fines collected against the violators. - Dominions were semi-independent polities under the British Crown, constituting the British Empire, beginning with Canadian Confederation in 1867. They included Canada, Australia, New Zealand, Newfoundland, South Africa, and the Irish Free State, and then from the late 1940s also India, Pakistan, and Ceylon (now Sri Lanka). The Balfour Declaration of 1926 recognised the Dominions as "autonomous Communities within the British Empire", and the 1931 Statute of Westminster granted them full legislative independence. - Hampton Roads is the name of both a body of water in Virginia and the surrounding metropolitan region in Southeastern Virginia and Northeastern North Carolina, United States. Comprising the Virginia BeachNorfolkNewport News, VANC metropolitan area and an extended Combined Statistical Area that includes the Elizabeth City, NC Micropolitan Statistical Area and Kill Devil Hills, NC Micropolitan Statistical Area, Hampton Roads is known for its large military presence, ice-free harbor, shipyards, coal piers, and miles of waterfront property and beaches, all of which contribute to the diversity and stability of the region's economy. - Virginia (, officially the Commonwealth of Virginia) is a state located in the Mid-Atlantic region of the United States, as well as in the historic Southeast. Virginia is nicknamed the "Old Dominion" due to its status as the first colonial possession established in mainland British America, and "Mother of Presidents" because eight U.S. presidents were born there, more than any other state. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most populous city, and Fairfax County is the most populous political subdivision. The Commonwealth's estimated population is over 8.3 million, which is slightly less than New York City. - The Hampton Roads Beltway is a loop of Interstate 64 and Interstate 664, which links the communities of the Virginia Peninsula and South Hampton Roads which surround the body of water known as Hampton Roads and comprise much of the region of the same name in the southeastern portion of Virginia in the United States. - The Downtown Tunnel on Interstate 264 crosses the Southern Branch of the Elizabeth River in the South Hampton Roads area of Virginia, US. It links the independent City of Portsmouth with the independent City of Norfolk. In conjunction with the Berkley Bridge, the Downtown Tunnel connects to Interstate 464 to the City of Chesapeake and a continuation I-264 to the downtown and Waterside areas of Norfolk, and on to Virginia Beach. Owned by the Virginia Department of Transportation (VDOT), it is operated and maintained by Elizabeth River Crossings under a 58-year publicprivate partnership concession agreement. Formerly a toll-free facility, open road tolling was implemented on February 1, 2014 by VDOT to help finance repairs and expansion to the tunnel.
