State Route 43 (SR 43) is a south to north highway in Tennessee that is 56.79 miles (91.39 km) long. It begins in Madison County and ends in Obion County.[3] State Route 43 is little-known by the general public by this designation as it is overlain by U.S. Route 45E for most of its length; the "43" designation is seen largely on mileposts. Two short sections of this route at Martin and South Fulton is fully signed. SR 43 from its southern terminus to Milan is designated as a Strategic Highway Network connector route servicing the Milan Arsenal.[4]
