The Brewery Grade Roundabout in The Dalles will be completely closed Sunday night with restricted driving there Monday and Tuesday nights.  Oregon Department of Transportation officials say that will be to allow crews to make improvements to the roadway at the roundabout and Highway 30 to near the intersection with State Road.  The work will be performed from 7 p.m. to 6 a.m. all three nights.  Workers will close the roundabout on Sunday at 7 p.m. to grind out the surface of the roadway around and near the roundabout and replace it with fresh asphalt.  On Monday and Tuesday nights flaggers will control traffic on one lane while the paving progresses to the east end of the project near State Road intersection.  The city of The Dalles and ODOT have partnered on the $370,000 project.
