About
The Newberg-Dundee Bypass addresses increasing traffic congestion by improving mobility and safety through Newberg and Dundee in Yamhill County.
Decades of work and financial contributions by local jurisdictions have helped move the project forward.
- In 2012, the Federal Highway Administration reviewed the Final Environmental Impact Statement and authorized the project.
- In 2018, we completed and opened Phase 1.
For many years, we have worked towards the next phase — which is now funded.
Phase 2A
We designed and are building improvements for the interchange where OR 18 meets OR 219, including the realignment of NE Wynooski Road. We started Phase 2A construction in 2025, and anticipate completing construction by 2027.
We are:
- Realigning OR 18 with a new connection to OR 219.
- Adding eastbound exit and westbound entrance ramps.
- Adding a bridge carrying the eastbound exit ramp over OR 219.
- Removing the old OR 18 alignment.
- Realigning Wynooski Road to meet the intersection of OR 219 and Wilsonville Road.
- Removing the old Wynooski Road alignment.
- Widening OR 219 for an additional travel lane, sidewalk, ADA ramps and drainage.
Phase 2B — Not funded for construction
We partially designed a road connecting the new interchange with OR 99W. Phase 2B is not yet funded for design completion and construction.
The road we are designing will have one lane in each direction with additional turning lanes or merge lanes as needed.
It will also have:
- Sound walls to help reduce noise levels at locations identified in the environmental impact statement and confirmed during design.
- Pedestrian connections at the public golf course in coordination with Chehalem Park and Recreation District.
- Eight bridges to cross Fernwood Road, creeks and local roads.
- Intersection improvements at the connection with OR 99W.
- Improvements to Veritas Lane and Corral Creek Road for safety and access to OR 99W.
