Highway 99W Newberg Dundee Bypass

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 ). ODOT, in coordination with the local jurisdictions, will soon be working on design of the next phase, from OR 219 to Rex Hill in Newberg.

Phase 1 of the Newberg-Dundee Bypass is complete. The four-mile expressway extends 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 included design enhancements , such as artistic elements that reflect the area’s surrounding natural landscape. 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 funded Phase 1, which opened in January 2018.

The Newberg-Dundee Bypass Phase 1 project is finished. So what’s next?



While everyone is still celebrating the completion and opening of the Newberg-Dundee Bypass Phase 1 project, ODOT is already moving ahead with Phase 2.

Before Phase 1 was completed, ODOT was able to use $10.5 million in cost savings from the project to begin making preemptive right of way purchases on Phase 2. In addition, the Oregon Legislature allocated $22 million in last year’s transportation package for ODOT to begin the design of Phase 2.

There is no timeline for when Phase 2 would be built, since no funding has yet been identified for construction. The design work should begin soon, but the earlier environmental studies provide the preliminary alignment and location of the roadway, culverts, bridges and other related structures.

Bypass Opened January 6, 2018



The long-awaited Newberg-Dundee Bypass Phase 1 has been completed and opens to travelers on Saturday, January 6, 2018.

The $252 million project was completed in just over four years on schedule and on budget. The project consists of almost 4 miles of new 2-lane roadway connecting OR 99W just west of Dundee to OR 219 south of Newberg. Springbrook Road was reconstructed to connect the Bypass with OR 99W east of downtown Newberg.

Travelers enter the Bypass at two new signalized intersections at OR 99W west of Dundee and at OR 219 south of Newberg. Also, the intersections of OR 219 and Springbrook Road and OR 99W and Springbrook Road were rebuilt with new signals that will help control the increased traffic using Springbrook Road.
