Travel through the Springfield Interchange should be easier for motorists, with the opening last week of a new bridge that carries traffic from I-95 North onto the Inner Loop toward Tysons Corner. On Thursday, Virginia Governor Tim Kaine accompanied a busload of elected officials and transportation experts during a peak hour tour of the new bridge. The ramp is 110 feet high, with four 12-foot lanes and two 12-foot shoulders, and eliminates the dangerous weaving maneuvers that challenged drivers heading north to or exiting to the Beltway’s Inner Loop. Gone is the right-hand cloverleaf exit that seemed to be headed in the opposite direction from Tysons Corner; exiting vehicles now will go up and over the highway to the left. Separated lanes will handle traffic continuing north to I-395.
