Repair funds not keeping up with aging bridges

In the wake of the bridge collapse in Minneapolis, Patrick Garmoe of the Duluth News Tribune reported on how age has affected bridges in the St. Louis County area of Minnesota. As the costs of repairing the bridges increased, 11 bridges in St. Louis County have been rated “fracture-critical” and at risk of collapse.
The News Tribune also reported on guidelines drafted by the county for determining when a bridge should be closed.
