This week will be one of the busiest times so far for construction crews south of Bend on Highway 97. ODOT spokesman Rex Holloway says if you drive between Bend and Redmond, you may want to allow a little extra time this week. Today, for example, the entrance ramp at Cottonwood will be shutdown: "The on ramp at Cottonwood is going to be closed, but just for the one day, but there's also going to be some switching of the lanes in that area, back and forth as they continue the work on the southbound lanes; so a lot of congestion in that area." He says you also need to watch for grooved pavement in that area. The Lava Butte project is the largest construction project in the region right now.
