Why did WSDOT improve the I-90 / US 97 interchange at Dolarway?

The old interchange experienced congestion due to heavy truck and vehicle traffic heading to and from Wenatchee, Ellensburg and I-90.

The End Result

This project improved traffic flow and reduced the 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 reduces the severity of collisions, improves traffic flow, and reduces wait times at the intersection.
