For the next five weeks, beginning tonight, the Inner Loop of the Capital Beltway will be reduced to one lane from 11 p.m. to 5 a.m. Sunday through Friday as crews erect a bridge for the Dulles rail project.
Big slabs of concrete will be pieced together over the Beltway at Route 23 in Virginia.
That bridge eventually will take Metro trains into the heart of Tysons Corner.
