MARYSVILLE – The new roundabout on Highway 9 near Marysville Getchell High School is not done, so traffic tie-ups are likely as school begins Sept. 4.
Detours that added up to 10 miles are no longer needed, but the roundabout itself is not finished.
The repaving project near Marysville-Pilchuck High School is done, so no extended delays are expected there.
The state Department of Transportation had hoped the roundabout at Highway 9 and 84th would be done by the start of school.
