Tillamook Street Improvements Tillamook, Oregon

A large-scale traffic redesign of the downtown core of Tillamook also adds a new connection for the community to enjoy pedestrian access to natural areas. Including the complete replacement of the Hoquarten Slough bridge and realignment of the couplet where the area’s main highways meet, the roadway design increases capacity and efficiency while reducing the threat of flooding.

Efficient Roadway Design and Construction

In partnership with the Oregon Department of Transportation (ODOT) and Quincy Engineering, this $25 million roadway design in downtown Tillamook makes significant improvements to both US101 and OR6. Along with the intersection between the two highways, reconstruction of the US101 bridge over Hoquarten Slough. Road redevelopment that daylighted storm drains and decreased run off, reduces potential flooding. The project also adds a new parklet and an extension of a pedestrian pathway across a reused rail bridge, connecting two natural areas on either side of Highway 6. Otak designed these improvements while managing construction through completion as part of the broader revitalization of downtown Tillamook.
