Ohio State Route 316

State Route 316 (SR 316) is a 14.05 mi long state highway located in Pickaway County, Ohio. The east–west route runs from SR 56 in the Five Points section of Monroe Township to SR 752 in Ashville.

Route description
SR 316 begins at a five-point intersection with SR 56 and Palestine–Williamsport Road in the aptly-named Five Points community within Monroe Township. The route heads east-northeast through farmland for about 4 mi before entering the village of Darbyville. After its brief stint in Darbyville, the route crosses the Big Darby Creek and climbs a hill before entering more farmland. SR 316 gradually curves due east and intersects SR 104 before crossing the Scioto River and entering South Bloomfield. In South Bloomfield, the road reaches US 23 (Walnut Street) at a signalized intersection. SR 316 turns south onto US 23 for six blocks before SR 316 turns east onto Ashville Road. As the road crosses over Mud Run and exits South Bloomfield, the road name becomes Pickaway Street. The road then enters Ashville as West Main Street. In the center of town, SR 316 turns north onto Long Street. The route ends at a four-way intersection with SR 752 though the road continues ahead as County Route 28.

History
The first section of SR 316 brought into the state highway system was a 1.5 mi spur from US 23 in South Bloomfield to Ashville in 1931. By 1937, the route was extended west to Five Points at SR 56. The connection between downtown Ashville and SR 752 was added to the state highway c. 1970.
