PORTLAND, Ore. — A section of Northwest Cornelius Pass Road in Multnomah County will be closed for about two months beginning on Monday.
The road will be closed between Highway 30 and Northwest Old Cornelius Pass Road. The closure will begin at 3 a.m. on Monday. The road is scheduled to reopen in late September.
Residents and emergency services will still be able to access the closed off portion of the road, the county said.
Drivers are advised to take the following alternate routes:
- Cars and Pickup Trucks: From Highway 30 take NW Newberry Road, NW Skyline Blvd. and NW Old Cornelius Pass Road to Washington County. A temporary traffic signal at NW Newberry Road will allow traffic to safely turn left onto Highway 30. Stop signs will be relocated along the detour route to create a free-flowing route.
- Trucks: From Highway 30 take I-405 south to Highway 26 west.
- Trucks Carrying Hazardous Loads: These trucks cannot use the Highway 26 tunnel in Portland. The detour is longer, taking I-5 south to Highway 217 north to Highway 26 west.
Multnomah County said it will be constructing safety improvements during the closure. The winding road has a history of crashes. Here are some of the improvements the county plans to make:
- Reduce some of the sharp curves
- Increase sight distance for drivers
- Improve road shoulders
- Install caution signs, guardrails and barriers
