Traffic ImpactUpdate Sept. 14, 2017
Traffic pattern change as of 9/14/2017: Drivers can now use the right lane to continue west on U.S. 26 beyond the SW 185th Avenue interchange. For the past several years, the right lane has been an exit-only lane for SW 185th Avenue. As of today, it is no longer an exit-only lane. By Friday morning (9/15), all the striping and signs will reflect this change.
This is a permanent change. When the project is complete, the right lane leading up to the Cornelius Pass Road exits will be an exit-only lane.
Starting early August and continuing for approximately 4 months, eastbound traffic in a ½ mile section between 185th Avenue and Cornelius Pass Road near Rock Creek, is shifted north into the center median. There are still two lanes of traffic, but the ordinary straight lanes of eastbound U.S. 26 has broad curves with narrow shoulders as drivers travel between concrete barriers. Please pay close attention as you drive through this area.
Expect daytime and nighttime work on U.S. 26 and Cornelius Pass Road until Dec. 2018. Visit the weekly construction update

** Road users should expect nighttime lane closures on U.S. 26 and Cornelius Pass Road, ramp closures, reduced shoulders and traffic shifts. No daytime lane closures on U.S. 26 are expected.
** The Rock Creek Trail under U.S. 26 will be closed for two separate weekends and six separate nights - with a detour in place - as the new bridge is constructed (both weekend closures happened in spring/summer 2017). There will also be intermittent flagging on the trail.
** There will be shoulder closures on U.S. 26 throughout most of the project. During the shoulder closures, those on bicycles must exit and take the signed detour on local roads.
** Work not requiring lane closures (such as building the sound wall) will take place during the day.
** Road users should expect increased congestion, noise and delays during construction.
** There will be periodic nighttime work on this project. Residences and businesses adjacent to the project area may experience daytime and nighttime construction noise. ODOT has obtained a nighttime noise variance from the City of Hillsboro. A noise hotline is available 24 hours a day for reporting noise concerns. That number is 971-673-5239.
