 River Road. So those are your choices. Not a huge delay any longer with a Sunday morning. This is the only thing on the Beltway, but not the only thing in Maryland. One other note, there is a work zone that will slow you on 97. They're working south again this weekend in Glen Burnie, passing Route 100 toward New Cut Road. Only a single file to the right will get you by. Your workarounds, the Baltimore-Washington Parkway and Route 2.
