Canada: Manitoba Highway closed by giant sinkhole

 A sinkhole 200 meters wide and more than five meters deep has closed Manitoba Highway 83 near Asessippi Provincial Park. Recent heavy rainfall may be responsible for the hole caused by an underground slide.
    The area has had problems for some time however from underground springs  that cause erosion. The highway is constantly being repaired. A dip will be filled in paved and then it starts to sink again. However this time the huge hole made the highway impassable.
   The hole was continuing to sink as of  Tuesday. Infrastructure and Transportation Department geotechnical experts are on site to determine the extent of the slide. The highway is closed from the park valley to the town of Roblin. However there is a detour and local traffic can still use other parts of the highway. No one knows when the highway can be reopened. For more see this article. The site if a little more than a half hour drive from where we live.
