Highway 99W Newberg Dundee Bypass

About the Project

ODOT has been working for many years with local communities to plan the Newberg-Dundee Bypass, an expressway that will significantly reduce traffic congestion on OR 99W and improve livability and overall traffic flow in the surrounding communities. The full bypass will be an 11-mile, four-lane highway around the cities of Newberg and Dundee. While the entire bypass has been approved, funding is only available for the first part of the project.

"Phase 1" will extend four miles from OR219 (near Wilsonville Road) to OR99W south of Dundee, with one travel lane in each direction. 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.

Construction is underway. Wildish Standard Paving of Eugene, Oregon, is building the Newberg portion of the Bypass (OR 219 to Chehalem Creek). Hamilton Construction of Springfield is building the west end of the Bypass near Dundee (OR 99W to Chehalem Creek). Improvements on Springbrook Road in Newberg are also planned but not yet under contract.

Phase 1 is expected to be completed in 2017.

Bypass construction progressing quickly

Work is well underway on a number of segments making up the Newberg-Dundee bypass, with more on the way as the project approaches its busiest construction year. The highway has started to take shape at both its eastern and western terminuses as well as in several sections along its span.

Traveling from east to west, motorists will turn off Highway 99W onto Springbrook Road at an intersection that will be completely reworked. Springbrook Road itself will see improvements down to its intersection with Highway 219, work which will take place next year after the contract goes out to bid in December.

A visible indication the bypass is moving forward

Traffic in Dundee was disrupted for periods over three days last week when contractors hauled into town 21 large concrete beams that will be used to construct three bridges over Hess Creek in the section of the Newberg-Dundee bypass near Eighth Street. In January, cranes will be dispatched to the area to lift the beams into place.
