Construction of the newest roundabout is due to start on Monday. This one is a one-lane roundabout at Oakes Avenue and Ship Harbor Boulebard/Glasgow Way.
The project includes stamped-brick pavement, pedestrian and bicyclist safety features, and a landscaped center.
Work will include traffic control, clearing, grubbing, grading, roadway excavation, installing an enclosed storm drainage system, placing gravel base and crushed surfacing top course, hot mix asphalt paving, curb and gutters, ADA ramps, landscaping, and other work.
The project is expected to be fully completed by May 28.
SRV Construction Inc. will construct the roundabout in two phases - the south half and north half - weekdays between 8 am and 5 pm.
Drivers through and near the construction zone should expect long delays and detours.
Alternate routes during construction:
- Anaco Beach Road to Kingsway to Jasper Way to Pennsylvania Avenue to Anacopper Mine Road to Oakes Avenue.
- Anaco Beach Road to Marine Drive to Havekost Road to A Avenue to D Avenue.
The detour route may change when the south half of the roundabout is constructed.
City staff will communicate with residents and other drivers with construction updates via mobile message trailers and other signage near and through the work zone.
As with all work zones, please drive slow and be cautious of workers near and in the roadway.
Frequent updates will be posted on the city Public Works Facebook page.
City staff also has contact information to more than 2,100 properties via email.
The stretch of Oakes Avenue/Highway 20 Spur is frequented by Washington State Ferries travelers and residents in the West End of Anacortes. Subdivisions in the area include San Juan Passage, Clearidge, Leeward Landing. Woolworth and Prutzman.
As traffic in the area has increased over the years, the efficiency of the intersection at Highway 20 Spur and Ship Harbor Boulevard has deteriorated to a D level of service.
Both the city and Washington State Department of Transportation favor intersection improvements in the way of a roundabout to better traffic flow as well as safety.
The city received federal funds to design and construct the project in 2016.
The roundabout and other intersection improvements will improve pedestrian and bicyclist safety, ease left turns onto the state highway and improve access into neighborhoods.
Roundabouts in general create safer road conditions with lower speeds and calmer traffic for drivers, pedestrians and bicyclists.
The intersection is listed in the city’s 2016 Comprehensive Plan as a failing intersection. This fix will make it a Level of Service A, defined as free flowing with minimal delays, for the indefinite future.
In addition, city staff is working with neighbors on landscaping and signage.
A $1.4 million contract was awarded to SRV Construction, which built the Highway 20 and Commercial Avenue roundabout, to construct the project.
Funding comes from:
- $821,750 federal grant
- $75,765 in waterline improvement funds
- $20,650 in ADA Ramp funds
- $796,000 in impact fee funds
