CLARK COUNTY – In an effort to keep drivers informed and safe, they will soon notice a change to the way they travel along southbound Interstate 5, in Clark County.
This week, WSDOT maintenance crews will begin work to install a series of highway warning signs throughout a nearly six mile stretch of I-5, between Ridgefield at milepost 14.32 and the I-5/I-205 junction at milepost 8.6.
These “rough road” and corresponding speed limit advisory signs will be strategically placed just after on-ramps and just before travelers’ approach rough patches of roadway, giving them an advanced warning of road conditions ahead.
This proactive approach helps to keep travelers informed of existing roadway conditions while keeping them moving until permanent repairs can be made.
Speed changes and sign locations
- Speed limit decreases from 70 MPH to 60 MPH between mileposts 14.32 and 9.63.
- Speed limit decreases from 60 MPH to 50 MPH between mileposts 9.63 and 8.6.
For your safety and the safety of road crews, during sign installation work, travelers should slow down as they approach the work zone, follow directional signs and expect delays.
