 It looks like one of those alternates is likely going to be your best bet from Upper Marlboro towards the Beltway for at least the next little while. Anyway, at least three vehicles involved in that serious crash on Route 4, Pennsylvania Avenue. On the Beltway, going past Branch Avenue towards 210 and the Woodrow Wilson Bridge, your lanes are open. Outerloop looks good as you head up past Commanders Field.
