Kent Island is the largest island in the Chesapeake Bay and a historic place in Maryland. To the east, a narrow channel known as the Kent Narrows barely separates the island from the Delmarva Peninsula, and on the other side, the island is separated from Sandy Point, an area near Annapolis, by roughly four miles of water. At only four miles wide, the main waterway of the bay is at its narrowest at this point and is spanned here by the Chesapeake Bay Bridge.
