A tunnel project in Florida is unique, he says. Design and construction are
A 98-year-old, accident-prone southeast Texas bridge is being upgraded following a long and bumpy bidding process. The U.S. Coast Guard declared the rolling-lift single-leaf bascule causeway bridge connecting Galveston Island with Texas a navigational hazard in 2001. Old bascule bridge was subjected to repeated barge collisions. The 108-ft-wide bridge often is struck by barges, costing more than $2 million in repairs each year, says Raymond Butler, Gulf Coast Intracoastal Canal Association�s former executive director. A new structure�designed by Galveston County with Mechanicsburg, Pa.-based Modjeski and Masters�triples the clearance width. Bids came in higher than expected in October, resulting in value-engineering
The U.S. Dept. of Transportation has pledged to work with an influential industry group to encourage more girls and young women to embark on transportation careers. DOT Secretary Ray LaHood last month signed a memorandum of cooperation (MOC) with the Women’s Transportation Seminar International last month in Washington D.C., noting the need in particular for environmental engineers is expected to rise by 30% over the next decade.

Members met with the U.S. DOT in April. “Lightbulbs
A massive effort to revamp the American air-traffic-control system from land-based to satellite-based equipment, dubbed NextGen, could result in greater flight efficiency and fuel cost savings at all major hubs by 2014, says Randolph Babbitt, Federal Aviation Administration chief. He also stressed the need for the next generation of land-side and air-side infrastructure. div id="articleExtrasA" div id="articleExtrasB" div id="articleExtras" Babbitt urged members of the American Association of Airport Executives last month in Dallas to work toward implementing multimodalism. “We have to advance our infrastructure to NextGen standards,” he said. “It’s the only way to keep pace with the rest of
The Washington State Dept. of Transportation is creating a list of best construction practices for floating bridges, based on results of tests conducted on a pontoon built at one-sixth the typical size. The best practices will be used by the design-build team that won the contract to build new pontoons for the state Route 520 Evergreen Point Floating Bridge. At 2,285 meters, SR 520�s bridge is the longest of its kind in the world.

Prefabricated segmental bridge designs that have helped speed construction and save money in many parts of the country may also have a place in seismically active regions, according to recent tests conducted by the University of Buffalo’s Department of Civil, Structural and Environmental Engineering, and its Multidisciplinary Center for Earthquake Engineering Research (MCEER). As part of a Federal Highway Administration-funded project exploring seismic response of Accelerated Bridge Construction (ABC) systems, the research team erected a half-scale 60-ft-long, eight-segment post-tensioned superstructure supported by 10 ft, 5 in. tall hollow piers on 10 x 10 ft concrete foundation blocks. The blocks were
Florida Gov. Charlie Crist (I) wielded his veto on May 28, returning $160 million in funds to the state Transportation Trust Fund and $19 million to the Tampa-Hillsborough County Expressway Authority. “It’s awesome,” says Bob Burleson, president of the Florida Transportation Builders’ Association (FTBA) in Tallahassee. “He sent a strong message to the Legislature and future legislatures to keep their hands off the trust fund.” Dick Kane, communications director for the Florida Dept. of Transportation in Tallahassee, issued a statement responding to the governor’s veto, saying, “We appreciate that the Governor recognizes the value and job opportunities the Florida Dept.
Advocates for a 269-mile magnetically levitated rail line between Las Vegas and Anaheim, Calif., are pressing the Federal Railroad Administration for $45 million originally appropriated in the six-year federal transportation bill in 2005. In an April 7 letter to FRA Administrator Joseph Szabo, Nevada Attorney General Catherine Cortez Masto described a scenario in which Nevada Dept. of Transportation repeatedly submitted scope of work plans since 2008, without receiving any response. “[We] steadfastly insist that the FRA comply with the Congressional mandate that the USDOT and the FRA take the steps necessary to allocate funding...for the maglev project,” she wrote. “We're
Carrying both commuters and water, tunnels have long snaked through the bedrock beneath New York City, but now the labyrinth is growing: Multiple projects are under way totaling nearly $2.5 billion, with several other tunneling jobs on the horizon. Photo: Launch Box Second Avenue subway’s first phase is a $350-million, four-year contract. “Everyone wants these projects done as soon as possible, so we have a flurry of underground activity,” says Gary A. Almeraris, vice president of Skanska USA Civil, Whitestone, N.Y., which has major contracts on three of the region’s biggest tunneling jobs. “This is good news for the New
Despite the financial crisis in southern European Union countries, the Portuguese government has launched construction of a $1.9-billion high-speed railroad to the Spanish border. But it has delayed bidding for a 13-km-long bridge that would carry the line north into Lisbon over the Tagus River. Map: RAVE Photo: RAVE The financial crisis has delayed bids on 13-km-long Tagus River crossing. Portugal’s first high-speed line will extend 165 km from Poceirão, some 34 km south of Lisbon, to Caia, halfway between Elvas, Portugal, and Badajoz, Spain. Due for completion in about four years, the line will carry trains running up to
