Tualatin-Sherwood Rd: Martinazzi Ave to I-5

The purpose of the project is to improve intersection operations to address known capacity issues at this location, while also working to improve pedestrian and bicycle safety. Potential elements of the project include adding a new eastbound lane along Tualatin-Sherwood Rd between Martinazzi Ave and Nyberg Rd, striping the intersection of Nyberg Rd, Tualatin-Sherwood Rd and the Fred Meyer vehicle entrance to improve circulation and pedestrian safety, improving advance signage for efficient and safe lane usage, and restriping eastbound lanes for I-5S, I-5N & I-5N/Nyberg Rd. use.
