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. 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). Improvements on Springbrook Road, OR 219 and OR 99W in Newberg are also in the design phase but not yet under contract.

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.


Latest News

Details are set for road design
May 4, 2016

Final plans have been approved that pave the way to build the eastern terminus of the Newberg-Dundee bypass, under the new design agreed upon earlier this spring.

Wilsonville Road will not intersect with Highway 219 directly across from the end of the bypass, as originally proposed, but will instead link up with the highway via a new road connection south of Wynooski Road. This design came about after a long battle between multiple jurisdictions, that came down to concerns over increased traffic utilizing Wilsonville Road as a cut-through from the bypass to I-5, versus concerns that altering the design would dump the traffic increases onto Newberg’s side streets.

Construction Alerts

Updated May 16, 2016
May 16, 2016

The following highlights anticipated activities on the bypass over the next week. Construction activities are often subject to change due to weather, equipment, supplies, or other variables. Please watch for signage and be alert in all of the work zones.

Springbrook/219 (widening and pipe replacement)

  • Crews have set up traffic signage and restriped travel lanes in work areas. Travel delays can be expected on OR 219 and Springbrook Road near work areas.
  • OR 219 at Industrial Way – signage and signal adjustments, widening, and pipe work are occurring in the area
  • Springbrook Road (south side) near 2nd Street - crews are building sound walls on the south side along the Nut Tree Ranch and Mountain View communities
  • Springbrook Road near Hayes – sidewalk work

Newberg (new bypass construction)

  • Construction continues on the nearly half mile long bridge structure between 11th Street and 14th Street in south Newberg. Early morning concrete pours must occur every other month for sections of the bridge deck. The concrete pour for a section of bridge deck can take up to 18 hours, so crews begin as early as 2 a.m. Three more of these dates are anticipated with the next in mid-June. Exact dates are determined closer to the anticipated date and are dependent on weather and concrete availability.
  • Construction continues on the bridge structures just east of Wynooski Road. Flaggers are assisting traffic on Wynooski Road, as necessary.

Dundee (new bypass construction)

  • The contractor continues to work on and around OR99W at Neiderberger Road and Parks Drive. Watch for signage and shifts in travel lanes on OR99W.
  • Rock and gravel supplies are often flagged across OR99W, causing brief delays.
  • Major bridge building work is occurring mostly out of view from the public on the structure that crosses Chehalem Creek. Neighbors are likely noticing the construction traffic that is accessing the work area with equipment and materials, such as pile supports and beams.
