After years of heavy construction, traffic detours, and bright orange cones, Washington County residents will soon celebrate the completion of major infrastructure projects on Roy Rogers Road and Tualatin-Sherwood Road.
A public ceremony and ribbon cutting are scheduled for 11 a.m. on Monday, Oct. 20, at Pioneer City Park in Sherwood (20570 S.W. Jonquil Terrace). The event will commemorate more than $150 million in improvements that mark a significant milestone in regional transportation and water infrastructure development.
Partnership and Vision
The improvements were spearheaded by Washington County Land Use & Transportation, working in collaboration with the cities of Sherwood and Tualatin and the Willamette Water Supply Program (WWSP).

The WWSP installed 66-inch water pipelines beneath the improved roadways, part of a 30-mile, seismically resilient regional water project. The system will deliver drinking water from the Willamette River near Wilsonville to communities in Beaverton, Hillsboro, and the Tualatin Valley Water District, enhancing water security and reliability for decades to come.
Washington County officials say the projects represent both a transportation and environmental achievement — creating safer, more efficient travel corridors while supporting regional growth and long-term sustainability.
Key Project Highlights
The celebration will highlight three major roadway projects completed or nearing completion:
1. Tualatin-Sherwood Road and Highway 99W Intersection
-
Project cost: $37.9 million
-
Timeline: September 2021 – September 2024
-
Upgrades: The intersection now features additional eastbound and westbound lanes, expanded turn lanes, bike lanes, and new street lighting. These improvements are expected to ease congestion and improve safety for thousands of daily commuters traveling between Sherwood and Tualatin.
2. Roy Rogers Road (Chicken Creek to Borchers Drive)
-
Project cost: $22.3 million
-
Timeline: July 2022 – October 2024
-
Upgrades: The roadway was widened to five travel lanes between Highway 99W and the urban growth boundary. Added multi-use paths for cyclists and pedestrians, sound walls, and street lighting create a safer and more community-friendly corridor.
3. Tualatin-Sherwood Road (Langer Farms Parkway to Teton Avenue)
-
Project cost: $88.6 million
-
Timeline: July 2022 – October 2025
-
Upgrades: This section was also expanded to five lanes, with new bike and pedestrian paths, modern lighting, and infrastructure enhancements designed to handle increasing traffic volumes as the surrounding areas continue to grow.
A Long-Awaited Milestone
Local officials, transportation planners, and community members are expected to attend Monday’s event to recognize the years of planning and collaboration that went into making these projects a reality.
“These improvements are a testament to what can be accomplished when local governments work together with shared goals,” said a Washington County transportation spokesperson. “Residents and commuters will now have safer, smoother, and more efficient routes through one of the fastest-growing areas in the region.”
For residents who have endured years of construction, the ribbon cutting represents both relief and progress — marking the transition from temporary inconvenience to long-term community benefit.
As Sherwood and Tualatin continue to expand, the enhanced corridors along Roy Rogers and Tualatin-Sherwood Roads are expected to support economic growth, improve safety, and provide better access for cyclists and pedestrians alike.
