Grand opening for 124th Avenue Extension, Willamette Water Supply pipeline is Oct. 30

For Immediate Release: Monday, October 08, 2018

UPDATE: Though work is substantially complete, the contractor does not expect 124th Avenue to open to traffic until January 2019. The celebration is being held now to avoid inclement weather.

A celebration of the Washington County 124th Avenue Extension project and the installation of the first section of the Willamette Water Supply Program pipeline will be at 10 a.m. Tuesday, Oct. 30.

The event will take place on the south side of Tualatin-Sherwood Road and 124th Avenue. Parking will be at Itel Corporate Center, 12000 SW Cimino St. Parking is limited; carpooling is encouraged. Speakers will include Washington County Commissioner Roy Rogers, District 3; County Chair Andy Duyck; and Tualatin Valley Water District Board of Commissioner Chair Bernice Bagnall.

While the road is substantially complete, additional work must be completed prior to opening the road for traffic. The contractor expects the road to open by Jan. 1, 2019. The celebration is being held in October to avoid inclement weather.

The project was a partnership between Washington County and Willamette Water Supply Program. Building the road and installing the water pipeline concurrently saved money and reduced construction impacts.

124th Avenue Extension; Tonquin Road and Grahams Ferry Road Improvements

The 124th Avenue Extension project was designed to provide another route connecting Tualatin and Wilsonville, allowing access to land designated for future industrial and employment development in the cities of Tualatin, Sherwood, and Wilsonville, including the Basalt Creek area.

Nearly 5 miles of new and/or improved roadway were constructed as part of this $30 million project. This included construction of SW 124th Avenue and Basalt Creek Parkway, new two-lane arterials between Tualatin-Sherwood and Grahams Ferry roads, and safety improvements to Tonquin and Grahams Ferry roads. 124th Avenue Extension Project
