LEONIA, N.J. (AP) — A town less than two miles from the George Washington Bridge is putting up the "keep out" sign for motorists seeking a shortcut to the world's busiest span. As a response to navigation apps that re-route some of the tens of thousands of vehicles headed to the bridge each morning, the New Jersey town of Leonia started barring the use of side streets to non-residents during the morning and evening commutes Monday.
