SR 101 over Ohio River Bridge
This 28-span 3,612-foot-long bridge connecting Indiana SR 156 with US 42 in Kentucky was a joint effort of the Indiana State Highway Commission, the Kentucky Department of Transportation, and the Army Corps of Engineers. The bridge crosses over the dam and locks near Markland, connecting many Ohio River communities. Prior to construction, the nearest bridges had been 25 miles downriver and 30 miles upriver. The bridge piers had been placed when the dam was built, but funding problems postponed actual design of the bridge for 12 years. The span lengths range from 32 to 349 feet. Various units were composed of continuous prestressed concrete I-beams, continuous composite plate girders, and continuous composite haunched plate girders. Many of the piers exceeded 60 feet in height. The haunched girders ranged from 8 to 14 feet deep.
