Ports & WaterwaysDriven by expanded sea trade expected with completion of the Panama Canal expansion project in 2015, U.S. ports and waterway construction is expected to skyrocket nearly 25 percent to $2.65 billion. Increased market activity is anticipated in California, Florida, Kentucky, Maryland, Massachusetts, Mississippi, New Jersey, New Hampshire, New York, Texas, Virginia and Washington. Airport Runways & Terminals Airport runway and terminal construction is expected to show growth in 28 states, with sector growth overall of 4.5 percent, reaching $12.5 billion. Market-driving states include: Alaska, Arizona, California, Florida, Illinois, New York, Ohio, Tennessee and Texas. Funding for airport projects is anticipated to increase over the next five years, largely tracking growth in passenger enplanements. Light Rail & Subways The uncertainty caused by the 33-month long delay in passage of MAP-21 will be felt in the subway and light rail markets. Construction activity is projected to be down by eight percent overall. There will be some bright spots, however. Based on recent contract awards, these states will be moving forward on key transit projects: California, Florida, Georgia, Hawaii, Illinois, Kansas, Massachusetts, New York, Oregon, Pennsylvania, Texas and Washington. The forecast uses an ARTBA econometric model that takes into account a number of economic variables at the federal, state and local level. It is measuring the public and private value of construction put in place, published by the U.S. Census Bureau. The ARTBA estimate of the private driveway and parking lot construction market is based on data from the U.S. Census Bureau's "Economic Business Census."
