 Route 1 works as an alternate. Rejoining the parkway from 197 puts you beyond any delay. And 95 in Maryland from the Capitol Beltway through the Baltimore Beltway northbound runs freely. There is a work zone south on 95, but not much fanfare. Passing 216 across to Patuxent, the right lane will be blocked for a bridge inspection. Plenty of room to maneuver.
