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.

ODOT officials says traffic pattern monitoring will beginimmediately after the new highway is opened to the public

The Newberg-Dundee bypass is on its home stretch of construction work before opening in mid- to late-December. Workers are putting the finishing touches on the first phase of the thoroughfare, painting the road striping as well as completing the artistic designs on some of the bridges. They are installing the last signage and completing guardrail work in some spots. The two new signalized intersections are all but ready to be activated and ODOT will be installing TripCheck cameras to show road conditions online.

"It's mainly just getting things to the point where we're ready to open it for traffic," said Lou Torres, spokesman for the Oregon Department of Transportation (ODOT).

A ribbon-cutting ceremony is scheduled for 2 p.m. Dec. 18, at a yet-to-be-determined location. Gov. Kate Brown and ODOT Director Matt Garrett will speak at the event.
