The Louisville mayor's office says the project to widen the Harrods Creek Bridge on River Road will resume soon.Mayor's spokesperson Kerri Richardson says the conservation group River Fields is dropping its legal challenges to the construction."From what we can tell the proper paperwork has not yet been filed in federal court, but we understand River Fields has decided to abandon their two federal lawsuits that have logjammed construction of the Harrods Creek Bridge and as soon as that paperwork is filed we hope to be back working on that project," Richardson said.The one-lane bridge in eastern Jefferson County was shut down by Louisville Metro Government last November after a state highway engineer deemed it unsafe for traffic.River Field has been opposed to widening the bridge. A federal appeals court recently denied the group's request for an injunction to stop the construction work, which began in June.Richardson says its not clear when the project will be completed, but it probably won't meet its original mid-December deadline.The attorney for River Fields was not immediately available for comment late Monday.
