 Elsewhere in Maryland, it's volume delays and stretches on the Baltimore-Washington Parkway and on the Capitol Beltway. In Dickerson-Montgomery County, the closure on 109 is between Slate Quarry Road and Thurston Road because of a serious crash and now an investigation. Riding in Virginia on 267 eastbound, the crash between Hunter Mill Road and the Toll Plaza underneath Trap Road has a single lane getting by.
