Route 1 is closed just south of Potomac Yard in Alexandria due to flooding in the roadway.

High water and mud spilled onto the roadway from an adjacent construction site, a tipster tells us. Earlier rains have since stopped, but so far no word as to how much longer Route 1 will remain shut down.

Traffic is reportedly being rerouted onto Potomac Avenue, which runs behind Potomac Yard and into Crystal City.
