​Welcome to the
Structure Management System (SMS) Website

Our mission is to provide a bridge inspection and inventory data management system that enables bridge personnel to consistently monitor and effectively preserve the quality of Ohio's bridges.

email SMS@dot.state.oh.us​ for help, questions, comments or concerns.




  • In the event you have bridges in SMS that are not your inspection responsibility simply ignore them and do not manipulate, delete, create or adjust any inspection, report or inventory information whatsoever.  

  •  ​

  • Follow the link to register​ for an SMS upcoming open lab.​

  • In accordance with 23 U.S.C. 144(d)(2), commencing on October 1, 2014, agencies are to begin collecting 

    element level data as each NHS highway bridge is field inspected in accordance with 23 CFR 650 Subpart C. 

    As a supplement to the National Bridge Inventory (NBI) data submission due April 1, 2015, and every year 

    thereafter, each State agency will also provide element level bridge inspection data for bridges on the NHS to 

    the FHWA for inclusion in the NBI. 


    The following urls provide additional information on the legislated changes and FHWA oversight practices.
