Olympic Region Bridge Cleaning Program - Project Map

Nisqually River bridges on I-5 getting cleaned

The Nisqually River bridges on I-5 are cleaned annually during two weekends in March. During the work, lanes of traffic are reduced from three to two so workers can safely clean the northbound and southbound bridges. An average of 118,000 vehicles per day use the Nisqually River Bridges.
