39th Ave SW Widening

The 39th Avenue SW from 11th to 17th is the last remaining portion of 39th (112th) to be widened.

​Work includes installation of pervious concrete sidewalks, pervious concrete roadway, Portland cement concrete intersections, asphalt paving, two new signal systems, illumination system, signal interconnect system, and new side sewer connections on several properties. Besides widening 39th between 11th and 17th, the project will provide for a U-turn for west bound cars on 39th just before 11th, will add a second left turn lane northbound on 14th and will overlay 17th north of 39th.

FAQ:

1. Why does the road curve and not include a left turn lane west of the 11th St intersection?

The original design for the project did have the full 5-lane section west of the 11th St SW/Costco entrance intersection. During right-of-way acquisition it was discovered that a 5-lane section would eliminate a high percentage of existing parking at the E&S Cabinets property. Consequently, the cost to acquire this property became prohibitively expensive, exceeding a half million dollars. Since the project was already exceeding the original budget without this additional cost, staff re-examined the need for a 5-lane section at this location. A 4-lane section was deemed adequate for the E&S Cabinet frontage. The altered design was submitted to the funding agency, the Transportation Improvement Board, and received their approval.

Traffic pattern alterations will be minimal until the project resumes in the spring to complete remaining work.

​Project Update for November 2016:
There have been delays which have been out of everyone's control. The contractor is working diligently at trying to get the project site open for full traffic before the holidays. The project will be under a Winter Weather Suspension and will not start back up again until after the New Year. At that time the remaining work items will be finished.
