CATHLAMET – Difficult site conditions and challenging work will delay the reopening of State Route 4 west of Cathlamet.
The road was scheduled to reopen on Friday, Oct. 2, and will now open in mid-October. The remaining work is weather dependent, so an exact re-opening date is not available.
Contractor crews working for the Washington State Department of Transportation are replacing two small-scale culverts with two larger fish-friendly box culverts. The new culverts measure 12 feet tall and up to 20 feet wide.
During the culvert installation water from a high tidal flow continually seeped through a series of barriers built to keep water out. Crews pumped the water out of the work zone, but that takes time, which contributed to the delay of this project.
“Replacing culverts this size is challenging work, and our contractor is working to finish the job as quickly as possible,” said Project Engineer Joanna Lowrey. “We appreciate the patience of people who use this stretch of SR 4 regularly.”
