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.

Bypass savings allocated for second phase land purchase
June 22, 2016
Newberg Graphic

The second phase of the Newberg-Dundee bypass project came a step closer to fruition last week with its addition into a state transportation funding program.

The Oregon Transportation Commission, a citizen policy-setting body for transportation projects statewide, voted June 16 to add the next phase of the bypass to the Statewide Transportation Improvement Program (STIP) and to allocate some funding toward the first steps on Phase 2.

About $10.5 million in savings on Phase 1 construction has been earmarked for what Newberg Mayor Bob Andrews described as “seed money” for the right-of-way purchase required for the next phase, which would run from the Phase 1 terminus at Highway 219 north to Highway 99W near the base of Rex Hill.

Construction work planned for 99W in Newberg
June 21, 2016

Be on the lookout for nighttime lane closures on 99W in Newberg during the week of June 20. ODOT is working on part of the Newberg-Dundee Bypass Phase 1 Project. Crews will close one eastbound lane of 99W east of Springbrook Road for a few nights. They’ll also close one westbound lane for a couple of nights. The work will happen between the hours of 8 p.m. and 7 a.m. More extensive nighttime work will happen there in late summer.

Late this summer, crews will widen the road, adding new turn lanes that would connect drivers on 99W to the Newberg-Dundee Bypass using Springbrook Road. Delays should be minimal, but the construction area will shift frequently and striping on the roadway will change often. The project will extend from 99W at Springbrook in Newberg to south of Dundee and will be completed in late 2017.

Construction Notice: June 15, 2016
June 15, 2016

The following highlights anticipated activities on the bypass over the next weeks. 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.

Updated June 15, 2016

OR99W near Springbrook (preparation for widening)

  • Beginning June 20th, the contractor will work nights for about a week on OR99W, just east of the intersection with Springbrook Road. They will close one eastbound lane of OR 99W for a few nights and then one westbound lane for a couple of nights. The work will occur at night between 8 p.m. and 7 a.m. This work is in preparation for more extensive night time construction at the intersection that is planned to begin in late summer.

Springbrook/219 (widening and pipe replacement)

  • Travel delays can be expected through active work areas.
    • OR 219 between 2nd Street and Wynooski
    • Springbrook Road between OR99W and OR219.
    • OR 219 at Industrial Way – signage and signal adjustments, widening, and pipe work are occurring in the area. Some night work occurs between 7 p.m. and 6 a.m. to install pipe, restripe travel lanes, and adjust signals. Excavation and road construction generally occurs during the day with travel lanes open. 
    • Springbrook Road (south side) near 2nd Street - crews are building sound walls on the south side of Springbrook Road near the Nut Tree Ranch and Mountain View communities. Expect flaggers to assist traffic alternating on one available lane during the day. Some pipe work and restriping activities occur at night.
    • Springbrook Road near Fred Meyer entrance – some concrete median removal and restriping. Watch for some slight changes in signage and striping.

Newberg (new bypass construction)

  • Construction continues on the nearly half mile long bridge structure between 11th Street and 14th Street in south Newberg.
  • Construction continues on the bridge structures just east of Wynooski Road. Flaggers are assisting traffic on Wynooski Road, as necessary.
  • The contractor is coordinating with the Sportsman Airpark and the Federal Aviation Administration FAA on construction activities in the Hess Creek area south of the airport runway. Nearest neighbors may notice early morning crews in the Hess Creek area. The airport will have some early morning closures over the next weeks. Check directly with the airport if you are planning to fly in/out of the Sportsman Airpark.  The contractor is coordinating construction timing to minimize impact to flights and ensure FAA safety requirements are met.

Dundee (new bypass construction)

  • The contractor continues to work on and around OR99W at Niederberger 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.
