F1NAL 2008-2011 STATEWIDE TRANSPORTATION IMPROVEMENT PROGRAM Bridge Replacement and Rehabilitation State Bridge Program Funds for the Bridge Replacement and Re- habilitation Program are administered cen- trallythrough the Bridge Section of ODOT's Highway Division. Oregon has about 2,700 state-owned bridges over 20 feet long and, therefore, subject to the National Bridge In- spection Standards (NBIS). By federal law, NBIS bridges must be inspected at least once every two years. The purpose of the Bridge Replacement and Rehabilitation Pro- gram is to preserve and, when necessary, re- place these NBIS bridges. Bridges less than 20 feet long and culverts are managed through separate replacement programs. The life expectancy of a bridge depends on the design standards in place at the time it was built, the construction materials used, and environmental and operating conditions since its construction. Many bridges that were constructed in the early to mid part of the 20th century require extensive rehabilita- tion and/or replacement, in part because of the construction methods used. Given the scale of this problem, the OTC has approved a policy for prioritizing investment in bridge repairs. That policy is outlined in the Bridge Options Report, which may be viewed online at: http://e og v.oregon.gov/ODOT/COMM/bridg e options.shtml The process of identifying bridge rehabilita- tion and replacement projects for the STIP relies on the Bridge Management System (BMS). ODOT maintains a complete inven- tory of all state (and local) bridges longer than 20 feet. The aggregation of structure inventory, condition data collected on a rou- tine basis, and appraisal data assigned ac- cording to national guidelines fulfill the re- quirements of the National Bridge Inventory (NBI). Data required by the NBIS and addi- tional data collected by ODOT bridge in- spectors provide the condition and inventory data necessary for the analysis of ODOT bridges. Applying criteria in twelve sepa- rate deficiency categories, and considering OTC and program goals and requirements, projects are selected on a statewide basis. After technical review and coordination with the regions and the statewide Bridge Leader- ship Team, the State Bridge Engineer rec- ommends alist of projects for the STIP.

ODOT manages the inspection of all bridges statewide, re- gardless of ownership, that are subject to federal inspection requirements. Structures of less than 20 feet are not inspected or con- sidered for funding under the Local Bridge Program. The purpose of the Local Bridge Program is to help local governments fund the preserva- tion and, when necessary, replacement of NBIS bridges. The program is considered a local program because funding is targeted to local governments for use on non-state fa- cilities. The program is administered state- wide by ODOT's Bridge Section. The pro- gram uses data from the BMS to monitor bridge conditions, establish repair and re- placement needs, and set program priorities. The Local Agency Bridge Selection Com- mittee provides program oversight. Page 14
