SR 970, Cle Elum Vicinity Paving
Send us your feedback on this project.
Kittitas County
This project paved eight miles of SR 903 from Oakes Avenue, east through Cle Elum for two miles, to the I-90/SR970 Interchange. Paving continued from where SR 970 begins, eastward for six miles to near the Teanaway River. The interchange ramps at I-90 and SR 970 were also paved. The project included asphalt grinding, expansion joint modifications on the I-90 over-crossing, guardrail improvements, new signs, pavement markings, and some utility adjustments.
The project provides a smoother, safer ride and preserves the pavement and bridge structure for another 10 to 15 years.

Construction Summary
We constructed the project according to the original design, with some minor modifications to the guardrail work.
The working relationship between the contractor and WSDOT was good. Problems were addressed in a timely manner before there was an impact on the schedule or cost. The project started June 28th and was completed in the scheduled 45 working days.
The working relationship with the City of Cle Elum was positive as well. We met with city officials regularly before and during the project to coordinate our work with planned city work and to explore work that could be combined in this and future planned projects.
Establishing these successful relationships quickly was more challenging than under usual conditions in that the project was outside the North Central Region. South Central Region Project Engineering offices were faced with too many projects while North Central had too few. In an effort to maximize resources across the entire agency, this became one of three SCR projects handed to NCR to manage through the construction phase last summer.
This was also one of three projects in the area that were being constructed at the same time. A paver from Ellensburg to the Blewett Pass Highway, this one from Cle Elum to the Blewett Pass Highway and a paver on Blewett Pass itself. The potential for severe traffic impacts and motorist confusion was high and was addressed with a comprehensive public notification plan utilizing Highway Advisory Radios (HARs at Cle Elum, Ellensburg, Lauderdale Junction and Big Y), media and web pages. The result was very few calls or complaints. Delays were never allowed to exceed 20 minutes on any of the three projects.
Our traffic control plan and the work zone safety plans were successful in that there were no personnel injuries reported during construction and no project related vehicle accidents.
