The Harrods Creek Bridge construction site in eastern Jefferson County remains idle this week after a federal judge ordered that renovation work on the one-lane span be halted.The environmental group River Fields has filed two lawsuits in an attempt to prevent Louisville Metro Government from widening the nearly century-old bridge to two lanes.The city went ahead with some work on the project in late June before a judge ordered construction halted last week.Kerri Richardson with the mayor's office says she's not sure what will happen next."It is a temporary restraining order. Unfortunately, a temporary restraining order doesn't come with an expiration date. it could be two days, it could be two weeks, it could be longer than that. It's up to the judge's discretion for him to take the time for him to review all aspects of the case and make a change as he sees fit," Richardson said.River Fields Don Cox says he's hopeful the two sides can hold discussions toward settling their dispute.The bridge has been closed to automobile traffic since a state engineer declared it unsafe late last year.
