Alarming Number Of U.S. Bridges Deemed “Structurally Deficient”
Washington D.C. – More than 47,000 of America’s bridges are in need of immediate repair, according to a new report.
The American Road and Transportation Builder’s Association (ARTBA) recently released its annual Bridge Report and concluded 47,052 of America’s 616,087 bridges are rated “structurally deficient” and are in need immediate repair.
ARTBA’s report analyzed the recently released U.S. Department of Transportation’s 2018 National Bridge Inventory (NBI) database.
ARTBA said 235,020 U.S. bridges have been identified as needing “structural repair, rehabilitation or replacement.”
The good news is that the number of bridges deemed “structurally deficient” is down from in recent years.
However, ARTBA reports nearly two-thirds of the bridges that are structurally deficient in 2018 have been classified as “structurally deficient” since 2014.
Additionally, ARTBA reports that at the current rate of repairs, it would take over 80 years to complete the necessary improvements and cost nearly $171 billion, based on average cost data published by FHWA.
Some of the notable structurally deficient bridges in 2018 include:
- New York’s Brooklyn Bridge;
- Memorial Bridge connecting Washington, D.C. at the Lincoln Memorial with Arlington, Va.;
- San Mateo-Hayward bridge crossing California’s San Francisco Bay – the longest bridge in California;
- Robert S. Maestri Bridge over Lake Pontchartrain in Louisiana;
- Albemarle Sound Bridge and the Lindsay C. Warren Bridge crossing the Alligator River in N.C.;
- Florida’s Pensacola Bay Bridge;
- Vicksburg Bridge in Miss.; and
- Lacey V. Murrow Memorial Bridge in Washington state.
ARTBA’s report points out the most traveled structurally deficient bridges are on parts of Route 101, Interstate 405 and Interstate 5 in California, where crossings are as high as 289,000 per day.
States with the largest number of structurally deficient bridges are: Iowa (4,675 bridges); Pennsylvania (3,770); Oklahoma (2,540); Illinois (2,273); Missouri (2,116); North Carolina (1,871); California (1,812); New York (1,757); Louisiana (1,678); and Mississippi (1,603).
