Owners of a building in the Near North Riverfront neighborhood that partially collapsed this morning had been waiting since December for a demolition permit to get approved. Individuals on the scene at the intersection of Tyler and North 10th streets this morning said that high winds likely caused the cave-in on the west side of the abandoned building that faces Interstate 70. An individual familiar with the building’s ownership said that last year he came into the building and found “the roof was on the floor.”
