US 12 - Anderson Rd to Moon Rd - Safety Improvement

Status

July 2017

  • After considering traffic needs and the community’s views, WSDOT has chosen to build roundabouts at the intersections of Anderson Road and Mood Road SW.
  • Learn more about roundabouts and how they work.  
  • Construction is slated for 2018.

Why is WSDOT planning changes to the US 12 intersections of   Anderson and Moon Roads?
WSDOT explored alternatives to help reduce the potential for collisions at the intersection of US 12 and Anderson Road as well as the nearby intersection of US 12 and Moon Road.

The solution will build modern roundabouts at both intersections. 

Unlike building a new traffic signal, a modern roundabout offers a cost-effective traffic solution that helps keep traffic moving.

Modern roundabouts are built to accommodate large vehicles including emergency vehicles, buses, and truck and trailer combinations.

WSDOT has been using roundabouts on Washington highways since 1997.

The End Result
Crews will build modern single-lane roundabouts at the intersections of Anderson and Moon Roads.

Anderson Road 
WSDOT will build a three-leg roundabout at this location.

Moon Road
WSDOT will build a four-leg roundabout at this location.


Both roundabouts will provide more efficient travel through the area. They are designed to accommodate large trucks traveling to and from nearby industrial and distribution businesses.
