A preliminary design for the roundabout set to be built this summer.
SNOHOMISH — A roundabout at Highway 9 at Avenue D will finally start construction Aug. 16.
Residents and travelers in the Snohomish area will need to prepare for an around-the-clock closure of State Route 9 beginning at 8 p.m., Tuesday, Aug. 16 to 5 a.m., Monday, Aug. 22.
Granite Construction Company contractor crews, working for the state Department of Transportation, will intermittently close SR 9 between Second and 30th streets to build a new roundabout at the intersection of SR 9 and Bickford Avenue/Avenue D.
While northbound SR 9 will remain closed for the full five days, southbound SR 9 will be open between 5 a.m. and 8 p.m. daily Aug. 17-19. Both directions of the highway will fully close from 8 p.m. Friday, Aug. 20 to 5 a.m. Monday, Aug. 22. The work is weather-dependent.
Highway 9 traffic will be detoured into Snohomish to funnel through Second Street to U.S. 2, and signs are already posted along Second Street.
Local traffic detours are:
• Southbound traffic: 30th Street to Bickford Avenue continue to Avenue D to Second Street to access southbound SR 9.
• Northbound traffic: Marsh Road to Airport Way continue to Avenue D to Bickford Avenue to 30th Street to access northbound SR 9.
It will be wide enough to accommodate semi-trucks with a truck apron, and northbound drivers will be given a right turn lane to hop onto Avenue D.
The roundabout will afford the ability for local traffic entering the highway to go either north or south. Currently, local traffic is directed to only turn right onto the highway -- northward if approaching from Avenue D, or southward if approaching from 19th Street (Bickford Avenue).
The intersection has had serious collisions in the past. In one, a driver was seriously injured in October 2019 after he allegedly didn’t stop for the stop sign and pulled out in front of an oncoming dump truck.
