EUGENE — The left lane will be closed in each direction on OR 569 Beltline Highway at Delta Highway through the weekend, from 10 p.m. Friday, Jan. 17, through 6 a.m. Monday, Jan. 20. The lane closures are needed for shafts to be drilled in the median of Beltline Highway, just east of the Delta Highway overpass. The shafts are part of the foundation for the new overpass that is part of the Beltline/Delta Interchange Project. During the same time, pilot vehicles will be used for rolling slowdowns to move equipment in and out of the construction zone. Expect slow traffic and delays from Northwest Expressway to Delta Highway on eastbound Beltline Highway. Travelers should stay alert and drive cautiously through the construction zone. The overhead lights on the north side of the interchange will not be lit until early next week as wiring is moved.
