Highway 99W Newberg Dundee Bypass

About the Project

Phase 1 of the Newberg-Dundee Bypass is currently under construction and expected to open in 2017. The four-mile expressway will extend from OR 219 to OR 99W south of Dundee, with one travel lane in each direction (see map). ODOT has been working for many years with local communities to plan the Bypass, which will significantly reduce traffic congestion on OR 99W and improve livability and overall traffic flow in the surrounding communities. Funding for Phase 1 is coming from the Oregon Legislature’s Jobs and Transportation Act, the federal government and contributions by Yamhill County, the cities of Newberg, Dundee and McMinnville, and the Confederated Tribes of the Grand Ronde.

Phase 1 is being built by Oregon firms under several contracts, which allows the project to be finished within a shorter time frame. Wildish Standard Paving is building the Newberg portion of the Bypass (OR 219 to Chehalem Creek). Hamilton Construction is building the portion of the Bypass near Dundee (OR 99W to Chehalem Creek). Improvements on Springbrook Road, OR 219 and OR 99W in Newberg are also in the design phase but not yet under contract.

The full 11-mile bypass is planned to be a four-lane expressway, two lanes in each direction, from Dayton to just east of Newberg (see map). While the full bypass has been approved, funding is only available for the phase currently under construction. The next phase to be built will depend on funding availability and coordination among the partners.
