With more than 25,400 state-owned highway bridges greater than or equal to 8 feet in length, 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 has oversight responsibility of 6,600 locally owned bridges greater than 20 feet in length, including monitoring to ensure they are inspected timely, that reports are provided to the local bridge owner, and to collaborate with the bridge owner on any required work where necessary. Our interactive statewide map details the condition — good, fair, or poor — of each of these bridges.
