Highway 109 is a 44-mile-long (71 km) highway in western Arkansas. It runs from the Ouachita Mountains to the Arkansas River Valley in Logan and Johnson counties. There are no spur routes associated with this highway.
Mount Magazine can be seen to the east on the southern portion of the route. It can also be seen south of the Highway 22 portion of the Route.
One of the most famous feature on the route is the Morrison Bluff Bridge, also known as the Ada Mills Bridge, over the Arkansas River. This 1.6-mile (2.6 km) bridge claims to be the longest over the Arkansas River and also the longest bridge in Arkansas.[1] However, it is shorter than two current Mississippi River bridges partially located in Arkansas, the Hernando de Soto Bridge and the Greenville Bridge.
