The Ohio Prestressers Association is an industry trade association organized to provide useful technical assistance to the precast/prestressed concrete bridge industry of producers, suppliers, and designers doing business in the State of Ohio. We promote the industry by being a trusted partner and resource, and work to make prestressed concrete the type choice for bridges.

My name is Mary Ellen Kimberlin, and as Executive Director, I am the point of contact for OPA. If I cannot answer your questions myself, I get timely input from the right people and share the information with you.

We offer plant tours at several locations:

Mount Vernon, Ohio
Columbus, Ohio
Melbourne, KY
Lexington, KY
Decatur, IN

Plant tours are very educational and give an up-close experience of the production process. For Professional Engineers, the credit counts for continuing education requirements.
