SR 150 - No See-Um Road Intersection Improvements


March 24, 2017

A $5,283,745.45 construction contract was awarded to Strider Construction Co. on March 16, 2017.  Work should begin later this spring with completion in 2018.

Public Open Houses are scheduled Tuesday 3/28 in Chelan and Wednesday 3/29 in Manson

The legislature's 2015 "Connecting Washington" revenue package included $6.5 Million in final design, right of way and construction funding to build a roundabout at the SR 150/NoSeeUm Rd. intersection on the north shore of Lake Chelan.

This I-2 Highway Capital Improvement Program Collision Prevention Safety Project would construct improvements to the intersection of SR 150 and No See-Um Road between Manson and Chelan.

Why is WSDOT improving this intersection?
Even with hundreds of yet-to-be-developed residential lots that will be accessed through this intersection, the current average traffic count has already risen to 10,000 vehicles per day. These volumes are producing more and longer delays for side-road traffic - the result of the lack of gaps to turn onto the highway. Faced with these conditions, drivers are sometimes making decisions that result in a collision or a near miss. 

The proposed roundabout is to reduce collisions, delays and improve bicycle and pedestrian mobility and access to Lake Chelan. 

The End Result
A new intersection to accommodate higher traffic volumes while reducing the potential for serious collisions.

Project Benefits

  • Reduced potential for serious collisions and improved traffic flow
  • Better motorist information from new signs and striping
  • Extended roadway life with new pavement
  • Reduced maintenance costs 

What is the project timeline?
The 2015 Connecting Washington budget includes $6.5 Million for design, acquisition of right of way and construction of the roundabout.
The project is expected to require 400 work days to complete.  Work should begin in the spring of 2017 with completion in 2018.
