The purpose of this program is to maintain and improve our bridges. Inspections identify necessary repairs and determine current load carrying capacity.
Bridge structures are regularly inspected
Inspection data is used to prioritize replacement and repairs
We have replaced or rehabilitated over 100 bridges since 1980
Mandated by U.S. Department of Transportation
In 1971 the National Bridge Inspection Standards (NBIS) were established
In 1978 funding was made available and all bridges were required to be inspected by December 1980
In 1979 and 1980 Frederick County had 109 bridges inspected using the new NBIS standards
Currently we have 219 bridges on the state inventory
They are organized by bridge numbers (such as F-0104)
All inspection data is stored in a database and transmitted to SHA electronically
