According to a story on WTOP Radio, congestion and traffic-filled roadways are threatening one of the biggest economic engines in the D.C. region. Traffic on three major routes around Dulles International Airport jumped 27 percent between 2000 and 2005, according to the Washington Airports Task Force. And it may get worse. The impacted roads are Routes 28, 50 and 606, known as the Dulles Loop.

Meanwhile, WTOP also reports that once travelers get to Dulles, the airport's new security screening area and train station, which have been a work-in-progress since 2001 and are part of a $7 billion improvement project at Dulles that includes a fourth runway, should speed up the process for travelers.
