City of Decorah workers have not been able yet to come up with a solution to the street problem on Upper Broadway.
Early last month a sinkhole developed and damaged the pavement near Phelps Park. Crews repaired the damage--and then a water main broke.
City engineering consultant Lindsay Erdman says an out-of-town company will be in Decorah Tuesday with "ground-penetrating radar" in an effort to figure out where the entire sinkhole is located. "We're trying to trace this," says Erdman. Once the sinkhole is mapped, Erdman hopes a more permanent solution to the sinkhole can be found.
