Public invited to learn more about Cornelius Pass Road widening
Southeast Cornelius Pass Road in Hillsboro is set to be widened in the early to mid-2020s.
While the construction project won't break ground for about three more years, the Washington County Department of Land Use & Transportation is getting a head start on its public outreach. It has scheduled an open house for the widening project on Tuesday, Sept. 10.
Members of the public are invited to drop by to ask questions of the project team and provide input from 5 to 7 p.m. Sept. 10 at R.A. Brown Middle School, located at 1505 S.E. Cornelius Pass Road.
Brown Middle School is situated just north of the stretch of Cornelius Pass Road that's set to be widened. The scope of work is from Southeast Frances Street to Tualatin Valley Highway, which is also signed as Highway 8.
The project will add a second travel lane in both directions between Frances Street and TV Highway. Right now, Cornelius Pass Road narrows from two lanes in each direction to one past Brown Middle School.
A dedicated right-turn lane onto Cornelius Pass Road for westbound traffic on TV Highway will also be constructed as part of the project.
As part of the widening, new sidewalks and bicycle lanes will also be put in along Cornelius Pass Road.
The project's estimated cost is about $17.1 million. Two-thirds of that money comes from Washington County, while the City of Hillsboro is contributing the remaining third.
The widening has been planned to accommodate an expected spike in traffic on Cornelius Pass Road as South Hillsboro develops. Until last year, the road's southbound terminus was TV Highway, but an extension was built that makes Cornelius Pass Road one of the major routes in the massive planned development.
Construction is expected to take place from 2022 to 2024. Concurrently, a 48-inch pipeline for drinking water will be laid down beneath the roadway as part of the Willamette Water Supply Program, which is building a network of water pipelines and other infrastructure to channel drinking water from the Willamette to water customers in Hillsboro and the Tualatin Valley Water District, which covers most of Aloha and Beaverton and part of Tigard.
The road widening in Hillsboro is completely separate from a more prominent project on Cornelius Pass Road that is currently ongoing.
Multnomah County crews closed Northwest Cornelius Pass Road last month between Northwest Old Cornelius Pass Road, just north of Hillsboro, and Northwest St. Helens Road, signed as Highway 30, to construct a series of safety upgrades through the West Hills. The road is expected to remain closed until late September.
That $5.65 million project in Multnomah County is largely state-funded.
The Frances Street to TV Highway project is also separate from another, larger project that widened Cornelius Pass Road in between Northeast Cornell Road and Highway 26 in Hillsboro earlier this decade. That work started in mid-2015, with the new travel lanes finally opening in early 2017.
