Louisville Metro Government is waiting for approval from two state agencies before repairing and re-opening a one-lane bridge in eastern Jefferson County.The nearly century-old bridge over Harrods Creek on River Road was closed in November after it was declared unsafe by a state inspector. The city announced plans to replace its guardrails. Because of the bridge’s age, the State Historic Preservation Office must approve the installation.And mayor’s office spokesperson Chris Poynter says there are now questions about the bridge’s overall structural integrity.“The Transportation Cabinet has asked us now to take a core sample from the decking of the bridge is and if this plan would work," he says.Poynter says he’s not sure when the two agencies will approve the repair plan.
