Travelers can expect lane and ramp closures through October with up to four closures of all northbound lanes in late August and September. ODOT evaluated options on how to install the new bridge joints and selected the option that keeps travel lanes open during the day.
- For up to 15 weeks starting late July, crews close three lanes on I-5 northbound and the Miley Road I-5 northbound entrance ramp near Charbonneau from 8 p.m. to 5 a.m. These closures are expected five nights per week during construction.
- Starting Thursday night, travelers can expect intermittent nighttime lane closures on I-5 northbound 8 p.m. to 5 a.m. at the Boone Bridge while crews gather site information and set up the work area under the bridge.
Beginning early July, travelers will also see a crane next to the Boone Bridge for exploratory geotechnical work on a separate project. There will be shoulder closures and impacts to the trail under the bridge.
More information available on ODOT's project webpage.

The Century Boulevard Extension Project creates a new route between north and south Hillsboro, improving mobility for travelers, neighbors, and Noble Woods Park-goers.
Construction will begin on August 3 and continue through spring 2028.
The project includes:
- Installing a new long-span bridge over Rock Creek
- Realignment of Century Boulevard between Ariel and Lois streets, creating a new four‑way signalized intersection at Century Boulevard and Lois Street
- Building enhanced street crossings with flashing beacons for safer access to transit, schools, and parks at:
- Borwick Street
- Dogwood Street
- Oelrich Street
- Adding improved sidewalks on Borwick (40-ft of new sidewalk around the intersection)
- 7-ft wide cycle tracks (raised surface for cyclists providing greater separation from vehicles)
- New streetlights to increase nighttime visibility
- A new center turn lane to help drivers and cyclists wait and turn more safely
- Creating an improved flood overflow channel using materials sourced on-site.
After the project is complete, the County will plant almost a thousand native trees in coordination with Hillsboro Parks & Recreation District and Clean Water Services.
