Snohomish County replaced two culverts under 280th St NE, northwest of Arlington. The pre-existing culverts were deemed fish-passage barriers. The new box culverts are designed to meet fish passage standards.
Construction began in July 2022 and end mid-September.
During construction there were single-lane closures. Emergency services were notified and were able to get through the project area.
This project cost approximately $1.1 million and was funded by Surface Water Management Utility fees.
