The William H. Harsha Bridge is a 2,100 ft long cable-stayed bridge over the Ohio River. The bridge utilizes deep steel plate girders and a precast concrete deck. It uses eight Lock-Up Devices (LUDs) between the deck and piers to allow for free thermal movement but will lock up during seismic events. This causes the connected elements to behave monolithically thereby distributing load between force resisting elements of the bridge.
