A new federal report has found that one in five Bay Area bridges is marked as a high-priority for monitoring and repair.
The study by Washington D.C.-based nonprofit Transportation for America found that the region had more “structurally deficient” bridges than the national average.
Representatives with the organization said the bridges have significant wear and tear or defects to at least one part, and they will continue to deteriorate over time.
Transportation for America also found that deferring maintenance of bridges and highways can cost three times as much as preventative repairs.
The group found that San Francisco had the highest percentage of structurally deficient bridges in the Bay Area, with more than 34 percent falling into that category.
Next was Alameda and San Mateo County, both with over 21 percent of bridges described as being structurally deficient.
