Bridge–tunnel
A bridge–tunnel is a persistent, unbroken road or rail connection across water that uses a combination of bridges and tunnels, and sometimes causeways, and does not involve intermittent connections such as drawbridges or ferries. Bridge–tunnels are a form of fixed link or fixed crossing which replaces ferry service. Fixed links are often, but not necessarily, intercontinental links between continents or transoceanic links to offshore islands. Tunnels and bridge–tunnels For water crossings, a tunnel is generally more costly to construct than a bridge. However, navigational considerations at some locations may limit the use of high bridges or drawbridge spans when crossing shipping channels, necessitating the use of a tunnel. Examples of such tunnels include the Downtown Tunnel and Midtown Tunnel under the Elizabeth River between Norfolk and Portsmouth, Virginia in the United States, the George Massey Tunnel in Greater Vancouver, Canada, and the Cross-Harbour Tunnel u ...

Chesapeake Bay Bridge–Tunnel
The Chesapeake Bay Bridge–Tunnel (CBBT, officially the Lucius J. Kellam Jr. Bridge–Tunnel) is a bridge–tunnel that crosses the mouth of the Chesapeake Bay between Delmarva and Hampton Roads in the U.S. state of Virginia. It opened in 1964, replacing ferries that had operated since the 1930s. A major project to dualize its bridges was completed in 1999, and a similar project to dualize one of its tunnels is currently underway. With of bridges and two tunnels, the CBBT is one of only 14 bridge–tunnel systems in the world and one of three in Hampton Roads. It carries US 13, which saves motorists roughly and hours on trips between Hampton Roads and the Delaware Valley compared with other routes through the Washington–Baltimore Metropolitan Area. , over 140 million vehicles have crossed the CBBT. The CBBT was built and is operated by the Chesapeake Bay Bridge and Tunnel District, a political subdivision of the Commonwealth of Virginia governed by the Chesape ...

Drawbridges
A drawbridge or draw-bridge is a type of moveable bridge typically at the entrance to a castle or tower surrounded by a moat. In some forms of English, including American English, the word ''drawbridge'' commonly refers to all types of moveable bridges, such as bascule bridges, vertical-lift bridges and swing bridges, but this article concerns the narrower historical definition of the term where the bridge is used in a defensive structure. As used in castles or defensive structures, drawbridges provide access across defensive structures when lowered, but can quickly be raised from within to deny entry to an enemy force. Castle drawbridges Medieval castles were usually defended by a ditch or moat, crossed by a wooden bridge. In early castles the bridge might be designed to be destroyed or removed in the event of an attack, but drawbridges became very common. A typical arrangement would have the drawbridge immediately outside a gatehouse, consisting of a wooden deck with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Victoria City, Hong Kong
The City of Victoria, often called Victoria City or simply Victoria, was the ''de facto'' capital of Hong Kong during its time as a British dependent territory. It was initially named Queenstown but was soon known as Victoria. It was one of the first urban settlements in Hong Kong and its boundaries are recorded in the Laws of Hong Kong.

Victoria Harbour
Victoria Harbour is a natural landform harbour in Hong Kong separating Hong Kong Island in the south from the Kowloon Peninsula to the north. The harbour's deep, sheltered waters and strategic location on South China Sea were instrumental in Hong Kong's establishment as a British colony in 1841 and its subsequent development as a trading centre. Throughout its history, the harbour has seen numerous reclamation projects undertaken on both shores, many of which have caused controversy in recent years. Environmental concerns have been expressed about the effects of these expansions, in terms of water quality and loss of natural habitat. It has also been proposed that benefits of land reclamation may be less than the effects of decreased harbour width, affecting the number of vessels passing through the harbour. Nonetheless Victoria Harbour still retains its founding role as a port for thousands of international vessels each year. The harbour is a major tourist attraction of ...

Cross-Harbour Tunnel
The Cross-Harbour Tunnel (abbreviated ''CHT'' or ''XHT'') is the first tunnel in Hong Kong built underwater. It consists of two steel road tunnels each with two lanes constructed using the single shell immersed tube method. It is the earliest of three vehicular harbour crossings in Hong Kong, opened for traffic in 1972. It was constructed under a 30-year private-sector franchise based on a build–operate–transfer model, and the title passed to the Hong Kong government in 1999 upon termination of the franchise. It has become one of the most congested roads in Hong Kong and the world, with 116,753 vehicles passing through it daily in 2013. History The Hong Kong government used the operator model "Build Operate Transfer", or "BOT", for the implementation of the tunnel project; Financing and construction was the responsibility of a private enterprise, which was granted a concession to operate and collect tolls for 30 years. The concession was given to the then Cross-Harbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
