WASHINGTON (AP) -- District of Columbia officials say they've fixed two of five bridges in the city categorized by federal officials as both "fracture critical" and "structurally deficient."
Experts say that combination of red flags is particularly problematic.
The district's Department of Transportation says one of the two now-fixed structures is the 11th Street Bridge carrying Interstate 695 over the Anacostia River, which was replaced this year with the help of federal highway dollars. Also, the department says a bridge on New York Avenue at First Street Northeast was repaired.
Three bridges are still "fracture critical," meaning they could collapse if a single, vital component fails, and "structurally deficient," meaning at least one major component has advanced deterioration. Those include the heavily traveled Frederick Douglass Bridge and the Whitney Young Memorial Bridge, both over the Anacostia.
