Portsmouth Bypass Disktron Installation

Ohio DOT’s First P3 Project Uses Disktron Bearings

 

The largest project in the history of Ohio, The Portsmouth Bypass, is a 16-mile long bypass of Portsmouth, Ohio via State Route 823/Southern Ohio Veterans Memorial Highway. 

Three of the steel plate girder bridges featured Disktron Bearings which ranged from 225 kips to 900 kips in vertical load capacity. One of the bridges also required uplift restraint, which was easily accommodated with the Disktron design.  The rotational capacity of these bearings was 0.025 radians and the displacements on the expansion bearings ranged from 3 to 6 inches.
