A year after the I-35 bridge collapsed in Minneapolis, federal and state officials are speaking out about the need to repair or replace aging bridges. WFPL's Elizabeth Kramer reports.The Kentucky Transportation Cabinet says about 2,800 bridges throughout Kentucky require repairs during a time when costs are rising and state revenues are declining.The state is responsible for maintaining more than half of those bridges according to cabinet official Robin Jenkins."Some of the things that weβre facing here in Kentucky is the age of our bridges, the cost of repairing our bridges and maintaining our bridges as well as our highway system and other transportation systems that we have" says Jenkins.The announcement comes on the same day that the American Association of State Highway and Transportation Officials released a national report on the condition of 600,000 bridges nationwide. The study finds that one in four bridges need work which could cost at least $140 billion dollars.
