SR 169 - SE 416th Intersection Project


October 2011

  • The Legislature eliminated all future funding for work at this intersection.
  • WSDOT traffic engineers will continue to monitor collisions at the intersection to determine whether conditions have changed and whether the Legislature needs to reconsider work at this area.

In 2005, the legislature provided funding to improve the intersection and reduce the risk of collisions at SR 169 and SE 416th Street, just north of Enumclaw.

In 2007, WSDOT recommended a roundabout to reduce the worst type of collisions in the area. The public did not support the roundabout because of the impact on local property. WSDOT agreed to make changes in the local speed limit.

In 2008 and 2009, the Legislature eliminated all future funding for changes to the intersection.

WSDOT traffic engineers continue to review collision data in the area and will make recommendations when conditions change. At this time, the type of collisions and daily traffic counts do not dictate a signal. 

Why is WSDOT improving the SR 169/SE 416th intersection?
Of the 18 collisions that occurred at this intersection between 2002-2007, 11 were injury collisions, and one was a disabling collision. Since 2007, there were fewer than three collisions annually.

The End Result
At this time, WSDOT continues to review traffic collisions and traffic volumes in the area.

Project Benefits
•  Safety.  Our goal is to reduce the possibility of high speed T-bone collisions that can occur when drivers turn onto or cross SR 169. We also want to  reduce the likelihood and severity of rear end collisions that can occur while drivers wait to turn left or slow to turn right from SR 169.

•  Congestion Relief.  Through traffic on SR 169 will no longer back up waiting for left-turning vehicles. 

What is the project timeline?
WSDOT engineers ended design work on this project due to lack of funding.
