SISTERS, OR -- The roundabout at Highway 20 and Locust Street in Sisters opens to all traffic Monday evening. Drivers will still see single-lane closures overnight. Between 8 p.m. and 7 a.m. Tuesday, crews are finishing pavement marking operations.

Access to South Locust Street and Hood avenue is closed until September; detours are in place.

Construction began in March. The full project should be done by October third.
