Dolarway Road links the City of Ellensburg’s downtown core to the redeveloping area of West Ellensburg – a growing retail, commercial, agricultural, industrial, recreational, and residential area. WHPacific created an innovative, cost-effective solution to help the City of Ellensburg’s flooding and traffic related issues on Dolarway Road.
To address the flooding issue, WHPacific raised the roadway and replaced the old undersized bridge at Reecer Creek. The new bridge consists of three-sided culverts; one culvert cell handles the normal flows and two additional cells pass the high flows that would otherwise flood the roadway. The project team also designed a storm water treatment for the road that minimized impact on the adjacent Reecer Creek floodplain.
To accommodate current and future traffic, WHPacific widened the road. Two through-lanes, bike lanes, sidewalks, curbs, gutters and a two-way left turn lane, which separates left turning traffic from the traffic traveling through the corridor, were added to Dolarway Road. The completed Dolarway Road Improvements Project provides a safe, low-maintenance, and sustainable corridor. Construction costs were $5.679 million and the project was completed in summer 2012. WHPacific’s services included:
- Alternative analysis
- Preliminary design
- Final design PS & E documents

- Right-of-way needs assessment
