The Mackinac Bridge closed once again due to falling ice on Tuesday, as warmer temperatures helped shed accumulations on the iconic structure. Officials said the warmer weather, paired with plentiful sunshine, is creating dangerous driving conditions on the bridge. "Ice continues to fall, but it's on its own schedule and we can't predict when it will clear completely and we can reopen," bridge officials explained. "Still, it's movement in the right direction." 🔗: https://www.cbsnews.com/detroit
