Thurston County Traffic: Expect Delays for Annual I-5 Nisqually River Bridge Cleaning


Submitted by Washington State Department of Transportation

Drivers using southbound Interstate 5 approaching the Nisqually River Bridge may experience delays during the morning hours of Saturday and Sunday, March 14-15. Washington State Department of Transportation bridge maintenance crews will close one lane of I-5 near the bridge for annual cleaning.

  • 4:30 a.m. to 10 a.m. Saturday and Sunday, March 14-15
