We were there this past weekend. J-Rider described it well. The washout is passable on foot, but it may be dicey with a bicycle, especially if the water is a little higher like it might be after the recent rains. Regular shoes and a light bike would be easier than cleats and a fully-packed bike. We'll be doing the ride on a tandem and there's no good way to get that across the water. There are train tracks nearby that cross the washout, but if a train comes there's no good way to get off the tracks, and the tracks are up a short gravel slope - not recommended.
There isn't an official marked road detour, but if you do go on the roads around the washout it's about a 7 mile or so ride (to get you around maybe 4.5 miles of trail), hilly, with some sections curvy and 55mph with no shoulder.
Check with the bike shop in Brunswick MD to see about shuttles, I did see one operating when we were there.
