A new federal report says nine percent of Vermont's bridges are "structurally deficient."
The 2013 National Bridge Inventory report by the Federal Highway Administration lists 251 of Vermont's 2,731 bridges as structurally deficient. That means that one or more components of the bridge, "such as deck, superstructure or substructure, is considered to be in 'poor' or worse condition," according to an analysis by the American Road and Transportation Builders Association.
The report also claims that 24 percent of Vermont bridges (652) are functionally obsolete by federal standards. Functionally obsolete means the bridges do not meet current design standards.
The report says the state of Vermont estimates it would cost at least $855 million to repair the 1,271 bridges in need of work.
Five of the 10 most-traveled bridges that are structurally deficient are on Interstates 89 and 91, the report says. About 70,000 cars a day pass over the deficient interstate bridges, the reports says.
