CEAO Bridge Load Rating Projects

Project Description

CEAO Bridge Load Rating Projects

Owner: Various Ohio County Engineers
Construction Cost: NA

Description

The County Engineer’s Association of Ohio (CEAO) conducted 5 rounds of load rating projects to assist Ohio’s county engineers in completing load ratings for their federal bridges. Load rating calculations and analyses were conducted for 15 counties and totaled over 500 bridges. Bridges were first field inspected and plan information was gathered prior to performing the load rating calculations. A final report was prepared for each bridge which contained the results of the analysis and any needed recommendations for posting the bridge.
