Snohomish County Public Work is proposing to upgrade existing guardrail and install new guardrail in multiple locations along Marsh Road. The guardrail improvements would begin at Lowell-Larimer Road and end approximately 4,000 feet west of State Route 9. Minor grading of the road shoulder would be required in some areas. The project will also update signage along Marsh Road.
This guardrail project is occurring in summer 2020.
