A very busy roundabout on Bend's west side is now closed for about 40 days. Hardy Hanson, City of Bend Street Operations Manager says the project at the intersection of Mt. Washington Drive, Reed Market Road and Century Drive is the biggest of the summer. "It’s our hope, and talking to the engineers that this will be a 40-year surface. And actually I believe it will be serviceable far beyond that. So actually it will be a good thing. If it works as well as we expect, I believe we'll be doing other roundabouts." Hanson says detours are well-signed in the area, and residents have been informed of the disruption for a little over a month. He says the roundabout has over 25,000 cars traveling on it each day, and there is a lot of wear and tear. Hanson says the projected reopen date is September second.
