Wenatchee North Paving
Send us your feedback on this project.
Chelan County
This project is located on US 97A near Wenatchee. It included three major elements: new approach slabs at the Entiat River Bridge, a 13-mile paving project from Wenatchee, north to the bridge, and new turning lanes at the entrance to the Lake Entiat Park. The turn lanes portion of the project was funded as a "Nickel Project" in the legislature's 2003 Transportation Funding package.
By combining the projects, the "Nickel Project" Entiat Park left -turn lanes construction was advanced a full year. As a result of a redesign to minimize underground utility impacts, a combined bidding process, and savings from consolidating the construction process, the costs for the "Nickel Project" were reduced from approximately $220,000 to $120,000.
The project provides a smoother ride for motorists and preserves the pavement and bridge structure for another 10 to 15 years, as well as increases motorist safety by adding left-turn storage at the Entiat Park entrance.

Construction Summary
We constructed the project according to the original design. Some minor modifications were made to the bridge repair work . These were changes that would not have been possible to determine during the design phase.
Our working relationship with the contractor was good. Problems were addressed in a timely manner which minimized impacts to the schedule and cost.
Work began on April 1 and was complete on June 29. Crews completed the project with two working days added for additional guardrail work and pavement repair. We timed the project to minimize conflict with both the cherry harvest beginning in late June and the tourist season. This route is a primary access to Lake Chelan from the Puget Sound area. Work was also suspended over the Washington State Apple Blossom Festival Grand Parade weekend. The timing of this project was also coordinated to eliminate conflict with another project on the opposite bank of the Columbia River on US 97 so travelers would not encounter delays on both routes to Lake Chelan and the Okanogan at the same time.
We used a comprehensive public and emergency services notification plan that included e-mail, fax, media and Web pages . As a result, few calls or complaints were received, despite the significant traffic impacts, particularly during the bridge repair phase of the work.
The project's traffic control plan and the work zone safety plans were successful. There were no project-related vehicle accidents and no personnel injuries reported during construction.
