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. Bridges and overpasses will include design enhancements such as artistic elements that reflect the area’s surrounding natural landscape. 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). K & E Excavating has been contracted to build improvements on Springbrook Road, OR 219 and OR 99W in Newberg. 

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.

'Aggressive' amount of work underway, while right of way roadblocks remain

Whether it’s the increase in traffic delays, more trucks motoring through neighborhoods or the occasional 2 a.m. concrete pour, the Newberg-Dundee bypass project has been making its presence felt in recent months.

“This summer is really the peak of the bypass construction,” Oregon Department of Transportation spokesman Lou Torres said Monday. “We’ve got work going everywhere.”

During the fall, possibly in September, crews will be paving the west end of the bypass near Dundee, which is a substantial finishing touch on that section.

Bypass savings allocated for second phase land purchase

The second phase of the Newberg-Dundee bypass project came a step closer to fruition last week with its addition into a state transportation funding program.

The Oregon Transportation Commission, a citizen policy-setting body for transportation projects statewide, voted June 16 to add the next phase of the bypass to the Statewide Transportation Improvement Program (STIP) and to allocate some funding toward the first steps on Phase 2.

About $10.5 million in savings on Phase 1 construction has been earmarked for what Newberg Mayor Bob Andrews described as “seed money” for the right-of-way purchase required for the next phase, which would run from the Phase 1 terminus at Highway 219 north to Highway 99W near the base of Rex Hill.
