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 Project Update

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.

ODOT Press Release

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.
