19th Avenue NE culvert replacement is planned for summer
Snohomish County plans to replace a failing culvert carrying Hibulb Creek under 19th Avenue NE near Marysville, with construction currently planned for July through September.
Why it matters
The work is meant to reduce the risk of road damage while improving fish access upstream, but it will also affect traffic on a local road during construction.
What happened
The county project page says Surface Water Management is scheduled to replace the culvert near 6304 19th Ave NE.
