Bridge Inspection & Maintenance

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
