It's been a rough winter - no question about it. Snow, cold temperatures, and frost that's been driven farther into the ground than usual. It's that frost that's causing problems on Hammond Avenue in Superior - between 21st and 28th streets. If you've driven that stretch of road in the last month or so, you've no doubt noticed the washboard-like roadway that everyone is talking about. Officials with the City of Superior are aware of the problem and have suggested that an investigation and fix probably won't happen until after the spring thaw.
