Fort McHenry Tunnel
The Fort McHenry Tunnel is a four-tube, bi-directional tunnel that carries traffic on Interstate 95 (I-95) underneath the Baltimore Harbor. The lowest point in the Interstate System under water, the tunnel is named for nearby Fort McHenry. The tunnel was constructed from May 1980 to November 1985, at a cost of about $750 million. At the time of its opening on November 23, 1985, it was the most expensive underwater tunnel project in the United States, but that figure has since been surpassed by the Big Dig project in Boston.DCRoads.net"Fort McHenry Tunnel: Historic Overview" Accessed 2011-07-11. The tunnel's annual traffic in 2009 was 43.4 million vehicles. , the toll rate for cars is $4.00 cash or $3.00 E-ZPass, paid in both directions. Vehicles with more than two axles pay additional amounts, up to $30.00 for six axles. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate 95 In Maryland
Interstate 95 (I-95) is an Interstate Highway running along the East Coast of the United States from Miami, Florida, north to the Canadian border in Houlton, Maine.

It is the longest Interstate Highway within Maryland and is one of the most traveled Interstate Highways in the state, especially between Baltimore and Washington, D.C., despite alternate routes along the corridor, such as the Baltimore–Washington Parkway, U.S. Route 1 (US 1), and US 29. Portions of the highway, including the Fort McHenry Tunnel and the Millard E. Tydings Memorial Bridge, are tolled. From the Woodrow Wilson Bridge to the community of College Park, it follows a portion of the Capital Beltway, completed in 1964 and numbered as I-95 in 1977. Prior to 1977, the route was intended to go on a n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hanover Street Bridge
The Hanover Street Bridge – officially, the Vietnam Veterans Memorial Bridge – is a bascule bridge crossing the middle branch of the Patapsco River along Hanover Street (Maryland Route 2) in Baltimore, Maryland. The bridge was built to replace the mile-long "Long Bridge" built by Richard Cromwell in 1856 to move products from his orchard in Anne Arundel County to downtown Baltimore. The Hanover Street Bridge connects the southern base of the industrialized South Baltimore to the neighborhood of Cherry Hill and Brooklyn. The bridge carries five lanes of traffic: two northbound, two southbound, and one reversible. It employs a lane control system and carries two sidewalks on either side. Designed by J. E. Greiner Company, the bridge was constructed in 1916 and is characterized as a Beaux Arts-style reinforced cantilever bridge. It is known for its beautiful arches as it spans the water. In the center of the bridge is a drawbridge span surrounded on four corners by classic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joint Venture
A joint venture (JV) is a business entity created by two or more parties, generally characterized by shared ownership, shared returns and risks, and shared governance. Companies typically pursue joint ventures for one of four reasons: to access a new market, particularly Emerging market; to gain scale efficiencies by combining assets and operations; to share risk for major investments or projects; or to access skills and capabilities. According to Gerard Baynham of Water Street Partners, there has been much negative press about joint ventures, but objective data indicate that they may actually outperform wholly owned and controlled affiliates. He writes, "A different narrative emerged from our recent analysis of U.S. Department of Commerce (DOC) data, collected from more than 20,000 entities. According to the DOC data, foreign joint ventures of U.S. companies realized a 5.5 percent average return on assets (ROA), while those companies’ wholly owned and controlled affiliates ( ...

Immersed Tube
An immersed tube (or immersed tunnel) is a kind of undersea tunnel composed of segments, constructed elsewhere and floated to the tunnel site to be sunk into place and then linked together. They are commonly used for road and rail crossings of rivers, estuaries and sea channels/harbours. Immersed tubes are often used in conjunction with other forms of tunnel at their end, such as a cut and cover or bored tunnel, which is usually necessary to continue the tunnel from near the water's edge to the entrance (portal) at the land surface. Construction The tunnel is made up of separate elements, each prefabricated in a manageable length, then having the ends sealed with bulkheads so they can be floated. At the same time, the corresponding parts of the path of the tunnel are prepared, with a trench on the bottom of the channel being dredged and graded to fine tolerances to support the elements. The next stage is to place the elements into place, each towed to the final location, in mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reinforced Concrete Box
Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beams, and wall panels for tilt up construction. In contrast, cast-in-place concrete is poured into site-specific forms and cured on site. Recently lightweight expanded polystyrene foam is being used as the cores of precast wall panels, saving weight and increasing thermal insulation. Precast stone is distinguished from precast concrete by the finer aggregate used in the mixture, so the result approaches the natural product. Overview Precast concrete is employed in both interior and exterior applications, from highway, bridge, and hi-rise projects to tilt-up building construction. By producing precast concrete in a controlled environment (typically referred to as a precast plant), the precast concrete is afforded the opportunity to prope ...
