    This animated video shows how the Manhattan West platform will be built in New York City. The first step involves building over the open tracks at the Penn Station rail yard using post-tension precast segmental bridge technology. This makes it possible to build above the site without disturbing train operations below. The segments will form a deck over the tracks, and then construction of two 60-story towers will begin.

  • Plan would allow Va. to proceed with 16 road, transit projects
    A transportation funding plan that eliminates the gas tax and increases the sales tax in Virginia would put $3.1 billion towards 16 projects in the state. Included among the projects are the second phase of work on the Dulles Metrorail project and construction of a new Interstate 66/Route 28 interchange. "Every corner of the Commonwealth will reap the benefits of safer roads, quicker commutes and increased access to public transportation if this plan is adopted," said Gov. Bob McDonnell.

  • Diverging diamond interchange will be first in Ind.
    The first diverging diamond interchange in Indiana could be completed in 2014, according to this piece. The diverging diamond interchange stops "frequent traffic backups in a high-traffic area" and is safer and less costly to build than cloverleaf or diamond interchanges. "The design is not superior in every situation, but there are a lot of benefits to the design that can make it the preferred interchange option," said Gilbert Chlewicki, a Maryland engineer.

  • Study seeks to extend life of concrete structures using bacteria
    A study led by the University of Ghent in Belgium and sponsored by the European Union is developing new technology that combines "limestone-producing bacteria" with concrete. The intent is to combat the effects of water and chemicals on concrete and thus extend the life of structures. "As the water seeps into the concrete, the bacteria will activate and start producing limestone, which will mend the cracks before they become a threat to the structure," said Carola Edvardsen, a concrete expert for engineering consulting firm Cowi.

    On July 1, $450 million will be available for energy-efficiency upgrades and clean-energy projects at California schools. During the four following years, $550 million will be available annually. Funding is a result of the passage of Proposition 39. An average retrofit could cut 30% off energy costs and save a school between $10,000 and $16,000 each year, according to estimates from the Environmental Protection Agency.

  • Keystone XL's new route across Neb. gets governor's approval
    TransCanada's proposed new route for its Keystone XL pipeline through Nebraska was cleared by Gov. Dave Heineman. "Over the past year, we have been listening to Nebraskans as we worked to identify a new route for the Keystone XL Pipeline that avoided the Sand Hills, protected sensitive areas, and addressed as many concerns as possible," said Russ Girling, TransCanada’s chief executive officer. Meanwhile, the U.S. State Department's ruling on the pipeline won't come before the end of the first quarter, said Victoria Nuland, a spokeswoman for the department.
