Alow-profile 350-meter-long, 15-m-wide suspension bridge designed by a U.K.-French team will carry part of a 25.5-kilometer planned light-rail system, called Metro West, across Dublin’s Liffey River to the city’s northeast corner. The Irish government’s Railway Procurement Agency, which oversaw design competition, wanted a low-key design. “Because it’s sensitive, we didn’t want [tall] towers,” says Davood Liaghat, technical director at Buro Happold Consultants Ltd., Bath, U.K. The structural firm, with Paris-based Explorations Architecture S.A., won RPA’s com-petition and a $190,000 prize.

Preliminary design of the world’s longest sunken tube tunnel is to begin following a recent contract award covering the roughly 30-km Hong Kong-Zhuhai-Macao fixed highway sea link, China. At 5.6-km, the tunnel will be some 2-km longer than the current record holder, on the Denmark-Sweden Øresund crossing, according to the Scandinavian tunnel’s designer, Copenhagen-based Cowi A.S. Cowi is also in the design consortium just hired by the Chinese government, which includes the Hong Kong office of Arup Group, Chinese Highway Plan and Design Institute Ltd. and Shanghai Tunnel and Design Institute.

With no prospect of quick action on a multi-year Federal Aviation Administration bill, the House has approved another in a series of extensions for FAA programs, including the agency's Airport Improvement Program construction grants.

The U.S. Dept. of Transportation has formally committed $900 million to help construct the first phase of the Silver Line, a 23-mile extension of Washington, D.C.’s Metrorail system to Dulles International Airport in Virginia. The funding, which has been closely scrutinized due to concerns about the $5.2-billion project’s schedule and cost, allows the Metropolitan Washington Airports Authority (MWAA) to move ahead with the initial $3.1-billion, 11.6-mile above-ground segment from the existing East Falls Church Station to Wiehle Road in Reston, Va. Dulles Transit Partners, the design-build consortium owned by Bechtel Infrastructure Inc. and Washington Group International, expects that phase to
