What to expect

US 101 construction at Thurston/Mason County line 

One direction US 101 is temporarily changed to handle both directions of traffic.  Speed limit is reduced to 45 mph.

Temporary changes will remain in place until crews build new bridges that carry US 101 over Griggs Creek. 

When work is complete during late September, crews will move traffic back with two lanes open in each direction. 

SR 108 open to travelers

State Route 108 near Kamilche has reopened to travelers. The reopening completed the third and final closure for the highway between Kamilche and McCleary.  People will see occasional daytime one-way alternating traffic at the work zone between Hurley Waldrip Road and West Eich Road
