PennDOT announced August 23 that both the sufficiency and condition ratings for all 25,000 state-maintained bridges are now available on PennDOT's website, www.dot.state.pa.us. The release of the list of 25,000 bridges follows closely the Aug 14 release of condition rating and sufficiency rating information for the 54 steel deck truss bridges that are similar in design to the collapsed Minnesota bridge. PennDOT also made a listing of closed and posted bridges available, along with maps of the locations of structurally deficient bridges, on the www.RideonPa.org website in May. Additionally, PennDOT posted the complete list of roughly 6,000 structurally deficient bridges on Aug. 3. Sufficiency rating is a composite number rating on a scale from 0 to 100 (with 0 being worst and 100 being best), and notes a bridge's overall capability. Fifty-five percent of the rating is based on structural condition, 30 percent is based on the bridge's ability to meet current traffic conditions and 15 percent is based on how essential the bridge is for public use. Sufficiency rating is used to determine eligibility for federal bridge funds. Despite record investments over the past four years, approximately 6,000 of Pennsylvania's 25,000 state-owned bridges are considered "structurally deficient," meaning they are in need of some level of repair. Approximately 800 bridges have weight or lane restrictions and 54 are closed.
