The Massachusetts Bay Transportation Authority announced on Aug. 2 that it plans to delay construction of the $1-billion Green Line extension to Somerville and Medford until fall 2018 or as late as summer 2020.It plans to purchase the required land and obtain permits before putting out a bid for design and construction to avoid loss of time and money—which happened to a commuter-rail project completed south of Boston in 2007. A day after the announcement, the city of Somerville circulated a petition stating that a four-year delay was unacceptable and demanded an accurate timeline for the project. It noted, “The

A congressional battle that blocked passage of a new stopgap Federal Aviation Administration bill has caused the FAA to issue stop-work orders on about 80 airport engineering and construction contracts, totaling more than $790 million, around the country.The failure to pass a new authorization bill before the old one expired on July 22 has also tied up an additional $2.5 billion in infrastructure funds, as FAA put a hold on awarding new grants from its Airport Improvement Program (AIP). Moreover, the agency furloughed about 4,000 of its 47,000 workers.The closing of the AIP grant window is a bigger problem for
Mass. Department of Transportation crews have completed installation of high-strength support straps on approximately 25,000 tunnel light fixtures in the Boston Big Dig Central Artery tunnels as a safety measure.The system was developed as a temporary three-to-five-year solution to the tunnel light corrosion issues while engineers evaluate options for a long-term solution, the agency noted in a July 25 press release..Paul Norton, principal at TranSystems in Boston, which served as transportation consultant for Mass DOT, says the high-strength polymer support strapping wraps around the entire lighting fixture and engages the steel Unistrut structure. “We studied 10 alternatives based on cost,
At a time when cutbacks threaten surface transportation programs across the U.S., a new economic analysis from the American Society of Civil Engineers says that simply maintaining current levels of investment won't be enough to avert long-term losses in productivity, jobs and household income.Drawing on widely used transportation planning models and consumer and industry data, “Failure to Act: The Economic Impact of Current Investment Trends in Surface Transportation,” forecasts that, within the next decade, the added costs of dealing with deteriorating highways, bridges and transit systems will result in the loss of more than 870,000 jobs and cut the nation's
