With thousands of acres of land to spare, Denver International Airport is setting its sights on becoming what officials dub an "airport city"—an aerotropolis featuring logistics and trade facilities, hotels, retail, museums, schools and intermodal connections. The concept of an airport-oriented "city" is not new, but recently it has become a hot topic.
The successful completion this spring of twin 2.1-mile-long bored tunnels in Seattle marks a literal breakthrough in that city's troubled history of light-rail construction. It also represents the halfway mark in the 3.15-mile, $1.9-billion project to connect downtown with the University of Washington.The 21-ft-dia tunnels run between Capitol Hill and the university.

States and localities are getting more active in advancing more infrastructure projects as deficit pressure prompts the federal government to pull back on its public works spending, says a new report on infrastructure trends.The study, “Infrastructure 2012: Spotlight on Leadership,” released on May 9 by the Urban Land Institute and consulting firm Ernst & Young LLP, also says financial stresses and economic slowdowns have caused some other countries, such as India, Brazil and even China, to scale down their infrastructure funding.Looking at the U.S., the report’s authors cite several examples of

New Jersey Gov. Chris Christie (R) is once again defending his October 2010 decision to kill the nearly $9-billion Trans-Hudson Express passenger-rail tunnel project that was, at the time, the country's largest public-works project.The federal Government Accountability Office released on April 10 a report claiming that Christie—a vocal anti-debt Republican—had exaggerated New Jersey's share of the tunnel's cost.The tunnel, nicknamed the Access the Region's Core (ARC) project, was expected to double commuter-train capacity between New Jersey and Manhattan. In September 2010, Christie shut down construction, which had started a year before, to conduct a 30-day review of the project. Less

The $3.25-billion effort to build massive new locks on both entrances of the Panama Canal has been delayed by six months beyond the previously announced schedule, said officials with the Panama Canal Authority, the agency that oversees the canal.The international consortium handling the lock's construction, Grupos Unidos por El Canal, notified the authority—known by its Spanish-language acronym, ACP — of the new altered schedule on April 3.The delay follows a weeklong work stoppage in January organized by SUNTRACS, one of Panama's largest construction labor unions.
