INFORMATION FOR OHIO MEDIA:
Understanding Ohios Bridge Inspection and Preservation Program
COLUMBUS (August 2, 2007) The Ohio Department of Transportation
joins the nation in monitoring the recovery and investigative efforts
in Minneapolis, Minnesota. Our sympathies go out to the families
impacted by this tragic event. As we wait to hear from the National
Transportation Safety Board on what may have caused this catastrophic
failure of the I-35W bridge structure, here is some background
information on Ohios Bridge Inspection and Preservation Program.
ODOT has an aggressive bridge inspection
program and devotes a significant amount of its annual budget to
Ohio has over 42,000 bridges, the second
largest number of bridges in the country. ODOT is responsible for
14,891 bridges on the state highway system.
Federal regulations require that every
bridge be inspected once every two years. However, Ohio law requires
all bridges to be inspected on an annual basis. This applies to the
Departments bridges as well as county and city bridges.
Bridges are inspected by trained
inspectors or consultants. These trained inspectors look at several
key appraisal factors, including the bridge deck, the
superstructure, and the piers and abutments that support the bridge.
ODOT has $239 million budgeted in 2008
to the repair, replacement, and maintenance of Ohio bridges under
ODOTs authority. We also have devoted $91 million to assist Ohios
Counties and Cities on their bridge projects.
