OK 99 Blue River, Johnston Co.

Built in 1933, this bridge stands just a few miles south of the Johnston/Pontotoc County Line. It is a 160-foot long hybrid K-Parker truss, similar in design to the OK 9 Rainy Mountain Creek bridge, but much heavier. You can visit the OK 9 bridge's page for a discussion on the 8-panel Parker to K-truss evolution.

This bridge also features stringer approaches, unfortunately, the original concrete "fence" style guards have been removed. The portals too have been modified as well to secure better height clearance.

Below, two additional photos of the bridge's unusual arrangement of web members.
