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.

Newberg-Dundee Bypass Revealed

Hundreds turn out Saturday to get a firsthand look at the route due to open later this year
With the first phase of the Newberg-Dundee bypass slated to open in a matter of months, hundreds gathered over the weekend to get an up-close view of what has been more than two decades in the making.

The event, billed as "Play on the Bypass," began early Saturday morning with a 5K run/walk that traveled a southwestern loop toward Dundee. More than 285 runners and walkers enjoyed the event under cloudy, but dry skies, and the atmosphere was celebratory.

"It was wonderful to see, well organized and … it was just fun to walk it, knowing someday all the cars will be here," said Annie Lee, a Newberg resident.

'Play on the Bypass' set for this Saturday

Officials from the Oregon Department of Transportation have set a firm date for their "Play on the Bypass" event, which will provide Newberg and Dundee residents with a chance to get an up close and personal look at the thoroughfare designed to decrease traffic traversing the two towns.

Set for 10 a.m. to 2 p.m. Saturday, ODOT and the two contractors responsible for constructing the first phase of the bypass are welcoming residents to walk, run or bike along the 3.5-mile route that stretches from Highway 219 south of Newberg to the "fish-hook" ramp just west of Dundee on Highway 99W.

"While the project is on schedule to be completed late this year, this casual and fun event provides a chance to see what has been built before the bypass opens to vehicles," a press release from ODOT stated.
