Drivers should be prepared for overnight closures of both directions of state Route 164/Griffin Avenue in Enumclaw this week.

Contractor crews working for the Washington State Department of Transportation will close the highway to remove old railroad tracks buried under the existing highway, excavate broken concrete panels and grind pavement between Porter and First Streets.

The highway will be closed Monday, June 23 to the morning of Thursday, June 26 nightly from 8 p.m. to 5 a.m. Drivers can also expect daily closures in one direction from 7 a.m. to 8 p.m. Monday through Thursday. Signed detours will be in place to guide drivers around the closures.

More than 1.5 miles of SR 164 between High Point Street and state Route 410 will be repaved this summer to preserve and extend the life of the highway. It was last paved in 1998. The $3.2 million project will also improve more than 90 sidewalk ramps and install a new traffic signal at the intersection of SR 410 and Watson Street.  Work will be complete by early fall.
