SR 100 paving project starts Aug. 6 in Ilwaco

Expect lane closures and travel delays on the coastal route

Starting Monday, Aug. 6, contractor crews with the Washington State Department of Transportation will start work on a short-term paving project that resurfaces State Route 100 through Ilwaco and Cape Disappointment State Park.

Throughout August, drivers can expect delays up to 20 minutes while crews flag single-lane traffic through the work zone. If the weather cooperates, paving and chip-seal work should wrap up by the end of the month.

Intermittent lane closures and short delays will continue into September while crews upgrade guardrail through Cape Disappointment State Park. The project is scheduled to be fully complete by the end of September.

The $1.2 million project preserves the highway by repairing aging pavement and applying a protective chip-seal coating on the four-mile loop through Cape Disappointment State Park, and upgrades sidewalk ramps along Spruce Street East in Ilwaco to meet current American with Disabilities Act standards.
