Demolition of a bridge and preparations for constructing a new one will shut down several major ramps in the Mixing Bowl between 9:30 p.m. to 5 a.m. until Saturday, Virginia Department of Transportation officials said.

“The impact is for motorists heading from the Wilson Bridge on the Inner Loop [Interstate] 495 west and north to Tysons Corner and also motorists in that same direction from the Inner Loop to [exit] 169 that takes them to Springfield,” said Steve Titunik, VDOT’s Springfield Interchange spokesman.
