Cornelius Pass Road closing for construction, weekend megaload moves
Northwest Cornelius Pass Road will close at night this weekend to accommodate moves of large industrial loads, then will close again for more than two months beginning on Monday, July 13.
Weekend closures for megaloads
Sections of Northwest Cornelius Pass Road will be closed at night on Friday and Saturday, July 10-11, to accommodate moves of very large industrial loads traveling from the port of Longview, Washington, to Intel's campus in Hillsboro. The moving vehicles are 189 feet long and 22 feet wide, requiring the two-lane road to be closed during the moves.
Northwest Cornelius Pass Road will be closed at times between Highway 30 and Northwest Germantown Road at night from 9 p.m. Friday until as late as 4 a.m. Sunday. The road will be open during the day, generally by 4 a.m.
• The road will be closed to traffic during the moves. The closed section will be phased, but will extend from Highway 30 to the Washington County line.
• Through traffic can avoid delays by using the detour off Highway 30 traveling south to I-405 and south to Highway 26 west.
• The megaloads will pull off the road periodically to let traffic pass, but drivers should expect delays and use alternate routes during the moves.
July 13 closure for construction
Northwest Cornelius Pass Road will be closed to through traffic between Highway 30 and Northwest Skyline Boulevard before the morning commute on Monday, July 13. Drivers will need to use alternate routes until the end of September while contractor Wildish Standard Paving completes safety improvements on the road.
Work will realign the two-lane road to reduce sharp curves at two locations. Last year the contractor completed other safety improvements in the corridor, including all work south of Northwest Skyline Boulevard.
While closed to through traffic, access will be maintained for local residents and emergency services. Wildish will set up a hard road closure just north of Northwest 8th Avenue where a culvert that carries a creek under the road will be replaced. No vehicles will be able to pass that point for several months. The second work location is at the sharp "S" curves north of Northwest Skyline Boulevard, where the road will be realigned. Flaggers will direct traffic through the curves when one lane is closed.
Alternate routes for through traffic
Cars, pickup trucks and motorcycles: From Highway 30, take Northwest Newberry Road and Northwest Skyline Boulevard to Northwest Cornelius Pass Road to Washington County. A temporary traffic signal at Northwest Newberry Road will allow traffic to safely turn left onto Highway 30.
Semi trucks: From Highway 30 take I-405 south to Highway 26 west. When Cornelius Pass Road is closed, Highway 26 is the nearest truck route to Washington County.
Trucks carrying hazardous loads cannot use the Highway 26 tunnel in Portland. The detour takes I-5 south to Highway 217 north to Highway 26 west.
Northwest Logie Trail Road will be closed to through traffic once Northwest Cornelius Pass Road is closed after July 13.
The Oregon Legislature provided $5.65 million for the Northwest Cornelius Pass project. The legislature also directed that the section of Northwest Cornelius Pass Road between Highway 30 and Highway 26 be transferred to the Oregon Department of Transportation after the project is completed.
