Work to repair a roughly 20-by-40-foot sinkhole at North Oakland and East North avenues in Milwaukee will continue for up to six weeks, according to the Milwaukee Department of Public Works.
A 66-inch diameter combined city sewer main collapsed Thursday night as a result of the heavy rains, leading to the sinkhole’s creation, said Cecilia Gilbert, communications manager for the Milwaukee DPW.
When the ground opened up, it took a city streetlight and a Cadillac Escalade with it. City crews were on site Friday, working to remove the vehicle and shut off affected utilities.
City utilities affected by the collapse included: sewer, water, traffic signals and street lighting, according to a release attributed to the Milwaukee DPW. Electrical conduits belonging to We Energies, Milwaukee, and AT&T Corp. also were affected, according to the release.
Milwaukee has hired Edward E. Gillen Co., Milwaukee, to build a containment shaft to stabilize the area.
Efforts to repair the area will continue on a 24-hour basis, according to the release. Sheet piling installation for improved stability was expected to continue into the beginning of this week.
The city also hired Rawson Contractors Inc., Sussex, to restore underground city facilities, including sewer and water mains, according to the release. Underground restoration work will begin after the sheet piling stabilization work is completed.
It could be up to six weeks until the area is restored and open to traffic, according to the release. For now, the intersection will remain closed and streets within a block of the site may remain closed. Pedestrians will be allowed in areas deemed safe.
