Highway 99W Newberg Dundee Bypass



About the Project

The Newberg-Dundee Bypass is a controlled-access expressway that will significantly reduce traffic congestion on OR99W and improve livability and traffic flow in the surrounding communities. "Phase 1" will extend four miles from OR219/Wilsonville Road to OR99W south of Dundee, with one travel lane in each direction.

The full bypass will be an 11-mile, four-lane highway around the cities of Newberg and Dundee. While the entire bypass has been approved, funding is only currently available for the first part of the project.

ODOT has moved into the final design stage of Phase 1. This includes final engineering and preparation of construction plans. There will be four contracts for construction, which allows some work to begin early while other elements are still being designed. In 2013, the community will see the installation of some stormwater retention areas and fill dirt being placed at the locations of roadway and bridges to be built between 2014 and 2017. Phase 1 is expected to be completed in 2017.
