 Half-mile stretch reported to be blocked right now. If you're in Virginia, on the outer loop, leaving the Georgetown Pike, headed toward the toll road, the work is in the right lane. Northbound at this point on 123, headed toward the Fairfax County Parkway, may have a single lane getting it by the work. Southbound I-95 coming past 123. That's where the left lane was blocked for the mobile work crew. Then further south coming past Dale City, that work zone is in the right lane, so watch out for that.
