Overview

The City of Anacortes Public Works Department hired SRV Construction to construct a one lane roundabout at the intersection of Oakes Avenue/Highway 20 Spur and Ship Harbor Boulevard/Glasgow Way in Spring 2020.

The project included pedestrian and bicyclist safety features, an enclosed storm drainage system, curb and gutters, ADA ramps, stamped-brick pavement, and a landscaped center.

History

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 increased over the years, the efficiency of the intersection at Ship Harbor Boulevard had deteriorated to a D Level of Service.

Both the city and Washington State Department of Transportation favored intersection improvements in the way of a roundabout to better traffic flow as well as safety.

Project Benefits

The roundabout and other intersection updates 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 was listed in the city’s 2016 Comprehensive Plan as a failing intersection. The fix made it an A Level of Service, defined as free flowing with minimal delays, for the indefinite future.

Funding

The cost of construction for this project was $1.4 million.

Funding sources:

  • $821,750 federal grant
  • $75,765 in waterline improvement funds
  • $20,650 in ADA Ramp funds
  • $796,000 in impact fee funds
