MISSOULA — A new survey finds one of every 13 highway bridges in
Montana is structurally deficient, and that an average of 80,000
motorists a day cross what the report ranks as the top three
busiest bridges in the state that are in that category.

The report released this week by Transportation for America says
federal guidelines peg a bridge structurally deficient if it has a
major defect that requires significant maintenance or
replacement.

The busiest bridges with problems are one over the Missouri
River in Great Falls, the Russell Street Bridge in Missoula, and
the Madison Street Bridge, also in Missoula.

In all, the survey found 391 Montana bridges structurally
deficient.

That’s 7.6 percent of bridges statewide. Nationally, the survey
found 11.5 percent of bridges to be structurally deficient.
