Basalt Creek Parkway is a new road in the Basalt Creek Planning Area, an 850-acre area between the cities of Tualatin and Wilsonville identified for future development. Basalt Creek Parkway, between Tonquin and Grahams Ferry roads, opened in 2017. 

We are designing a Basalt Creek Parkway extension between Grahams Ferry and Boones Ferry roads. Basalt Creek Parkway will be a five-lane road with bicycle and pedestrian facilities, drainage and street lighting. The project includes a bridge across Sealy Ditch and a new signalized intersection at Boones Ferry Road.

Construction start (expected): Summer 2023
Construction finish (expected): Fall 2024
