Bridges

With more than 25,000 state-owned bridges, Pennsylvania has the third-largest number of bridges in the nation. The average age of bridges on the state system is over 50 years old.

PennDOT is committed to maintaining and improving bridges through bridge preservation activities, including painting, deck joint repair or replacement, rigid deck overlays, etc. In the long run, preservation saves money by extending bridge service life, thus deferring the need for major rehabilitation of bridges.

PennDOT is responsible for the safety inspection of more than 30,000 bridges owned by the state, municipalities, or other agencies. Our interactive statewide map details the condition — good, fair, or poor — of each of these bridges.
