Public works crews are beginning spring clean-up efforts as temperatures get warmer.  The town of Cochrane is asking that residents give those crews, sweepers, trackless machines, water tankers and other equipment time and space to complete their work.  Manager of Public Works for the town of Kapuskasing, Eric Cote says once the ground and roads are no longer frozen public works can get started on filling in potholes permanently.  He says clean-up efforts will be starting soon.
