Work has on started on the site of the $3.2 million Slide Ridge Retrofit bridge project. They are preparing the site for construction, including clearing and grubbing and building the bypass route around the project site on South Lakeshore Road on the south shore of Lake Chelan. The short bypass road will be used for most of the project, with automated signals utilized on either end.
There is a shoulder closure at the work site because of the preparation work. The project includes the installation of a new 108 foot bridge at Slide Ridge, which will allow debris coming off of the ridge to flow under the bridge, not over the roadway.
The project will take about six months to complete, with girder installation planned for September and paving of the new bridge in late October.
The construction project was awarded to KRCI of East Wenatchee earlier this year.
The contractor will not be working July 2-5 because of the July 4th holiday.
The slide area is frequently hit by intense rain and thunderstorms that deliver more than an inch of rainfall in an hour’s time. Rainfall on Slide Ridge results in water flowing down its steep slopes, where it dislodges rock down the slope to Lake Chelan. The storms have left a mix of woody, rocky and muddy debris as high as 12 feet on South Lakeshore Road, the only north-south corridor for residents living along the west side of Lake Chelan, one of the largest tourist destinations in the state.
Cleanup costs of removing the material, hauling it offsite and re-establishing the existing engineered channel have cost taxpayers nearly $1 million from 2003 to 2019.
Antoine Creek Road Culvert Replacement: The contractor has completed installing the three box culverts. The bypass lane has been eliminated; however, the roadway in the project area is graveled. It will be paved in mid-July. Motorists are reminded to lower their speeds on the short gravel portion. The contractor will not be working July 2-5 because of the July 4th holiday.
