 This is the big story now, the outer loop in Bethesda. Before you get to the big curve, all traffic is being diverted at Old Georgetown Road, which is exit 36. Going either direction, going north to Democracy can put you back on. You can travel underneath of the big curve so far. Watch for any direction. If you go south, you can rejoin from River Road. A few workarounds for an early Sunday. Those at the front of the line who have been sitting now for over an hour.
