Status

August 2017

  • Construction is underway and the four-way stop is now in a roundabout configuration.

Why is WSDOT improving the I-90 / US 97 interchange at Dolarway?
The existing interchange experiences congestion due to heavy truck and vehicle traffic heading to and from Wenatchee, Ellensburg and I-90.

The End Result
This project will improve traffic flow and reduce risk of collisions by adding a right turn lane to the westbound I-90 off-ramp, constructing a roundabout at the US 97 Dolarway intersection, and adding a lane on northbound US 97 between the I-90 off-ramp and Dolarway.

Project Benefits
A roundabout will reduce the severity of collisions.

A roundabout will improve traffic flow and reduce wait times at this intersection.

What is the project timeline?
Construction Begins: June 2017
