Chip sealing preserves the integrity and life of deteriorating roadway by applying a Bituminous Surface Treatment (BST) seal coat of oil and gravel (chips) to the existing pavement. Restoration is necessary before the underlying road structure is damaged, requiring a much more expensive rebuild.

Crews replaced a failing culvert, that was causing a sinkhole on SR 4 near Loop Road in Wahkiakum County. The pipe used to construct the old culvert was corroded and no longer directing water away from a nearby slope. On Thursday, June 15, crews finished installation of a new culvert made of thick, heavy plastic, which will last longer and reduce long-term maintenance costs. Culverts collect water runoff and help prevent water from settling under the surface of the roadway, which extends the life of the sub-surface roadway structure.
