Starting this week, Deschutes County will begin some road overlay projects during day hours that could affect your travel route.  George Kolb, County Engineer says these will not be  major construction projects, but an annual or semi-annual maintenance project.  “We have an overlay program that we budget for. And we base the roads that we overlay on what we call the pavement management system. It rates our roads and we look at those ratings. And we'll use that in combination with how much traffic is on that road to determine which ones we select for overlays that year."  Beginning today one side of Bear Creek road from Highway 20 to Ten Bar Ranch Road will begin Tuesday the other side of the road will be overlayed.  Then Brookswood from Bend City limits to Baker Road will begin.  Most projects will only take two to three days; so expect delays of up to 20 minutes in those areas.  The City of Bend is also working on Empire and Brookswood this week.
