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.

Save the Date – Play on the Bypass

Saturday, September 23rd, 10 a.m.–2 p.m. (Details still underway)

ODOT is opening the bypass to people (but not cars!) on one day - Saturday, September 23rd from 10 a.m. to 2 p.m. This is your chance to see what’s been built before the Newberg-Dundee Bypass (Oregon 18) opens to vehicles this winter. Construction is on track to be complete at the end of 2017.

Bring your friends, family, a water bottle, and even a picnic and take a break on Oregon’s (soon-to-be) newest state road. We invite you to get active as you take a sneak peek of the new road. You can walk, bike, run, or roll. For this day only, you can even hang out in the middle of the road. Leashed dogs are invited. Alcohol should stay at home.

The bypass is designed as a highway and does not have sidewalks or bike lanes, so this is a once-in-a-lifetime chance to see the road from a different perspective before it opens this winter to cars and trucks. More details will be available soon on how to access the event and where to park.

Chehalem Park and Recreation District will also be hosting a 5K run earlier that morning. Registration details will be available soon.

This is a casual, fun event. A formal ribbon cutting will be held when the road is complete. For more information about the Newberg-Dundee Bypass project, or if you have questions about the event, contact Kristen Kibler at JLA Public Involvement on behalf of ODOT at (503) 235-5881 x104.

U-turns now banned at Highway 99W and Springbrook Road

Change affects only southwest-bound turns as road expands for the completion of the Newberg-Dundee bypass

As work along Springbrook Road continues under the Newberg-Dundee bypass project, state officials are warning that drivers will no longer be able to make a u-turn from southwest-bound Highway 99W.

The change barring u-turns from that specific side of 99W is a safety precaution as the intersection is overhauled to handle more traffic heading toward the new bypass route south of Newberg, according to a press release from the Oregon Department of Transportation.
