Aiming to reduce congestion on I-5 through Tacoma, Washington, the Westbound Nalley Valley Iinterchange is the first of three phases of bridge construction in the historic Nalley Valley. The project will distribute traffic between I-5 and the Tacoma Narrows Bridge toward the Olympic Peninsula. An array of new structures will replace seismically obsolete bridges and provide a much needed increase in traffic capacity.
Hatcher Technical worked with the construction engineer McNary Bergeron to provide:
- Design drawings for the McNary Bergeron redesigned TEB & SW Line bridges
- Fully integrated shop drawings of the SW Line bridge
