SR 136 @ LOOKOUT CREEK

construction work program

The bridge on State Route 136 over Lookout Creek, Structure ID 083-0014-0, was built in 1940 and widened in 1988. The structure consists of four spans of steel beams on concrete caps with concrete columns on the original portion and steel piles on the widened portion. The design loading used was an H-15 truck, which is below current design standards. Overall the bridge is in satisfactory condition. The foundation elevations are unknown,classifying the bridge as scour critical. The deck is in fair condition with moderate surface abrasion on the originalportion of the deck as well as minor to moderate cracking throughout. The superstructure is in good condition with minor spalling on concrete diaphragms. The substructure is in satisfactory condition with minor cracking and random spalls on the backwall. Due to the age of the structure, not meeting current design standards, and the bridge classified as scour critical, replacement of this bridge is recommended.
