SISTERS, OR -- Construction begins Tuesday on a new roundabout in Sisters, at Highway 20 and Locust. East/west traffic on Highway 20 will stay open. Cascade Avenue will also remain open during construction but North Locust close through the end of May. Other closures are expected later this summer.

ODOT hosts an open house Monday afternoon at Sisters Elementary from 3:30 to 5:30 p.m., to talk about detours and other impacts of the work. Click HERE for more information.

The majority of the project should wrap up around Memorial Day, although some work will continue into fall.
