Savor It, It's Not a Time Saver
I have often recommended using the Delmarva Peninsula as an alternative to I-95 for travel along the east coast, but not because it saves time. While you could conceivably save time by just hoofing it up US-13 (and DE-1 once you get up to Dover, DE) this is a route to be savored for the many side trips it offers including Chincoteague and Assateague Islands, the quaint towns of Maryland's Eastern Shore, and the many wildlife sanctuaries which dot the Chesapeake Bay to the west and the Atlantic Ocean/Delaware Bay to the east. Oh, and you want to be careful of the distinction between the Chesapeake Bay Bridge which crosses at mid-bay between Annapolis and Kent Island, and the Chesapeake Bay Bridge-Tunnel which crosses at the mouth of the bay between Chesapeake Beach (Norfolk) and Cape Charles.
