The Wyoming Department of Transportation issued a media release that states that the West bound lanes of I-90 south of Sheridan have been re-opened to traffic and normal two-way, two-lane interstate traffic has resumed. The West bound lanes of I-90 were closed on July 8, 2011 due to a landslide. Since July all traffic has been split and was shifted to the East bound lanes and speeds were reduced.
The release further states that the contractor was in the process of a mill and overlay project that included some minor slide repairs. The land slide that created the closure was in the current construction project at mile-post 31, so the contractor was able to begin immediately repairing the major slide.
They removed 112-thousand cubic yards of slide debris and replaced it with light weight back fill material to repair the slide. The contractor also finished the mill and overlay project in the West bound lanes, however because of the extra time it took to repair the slide at mile-post 31, and the fact that all the traffic was in the East bound lanes they were unable to finish the mill and overlay project in the East bound lanes. The contractor will return in the spring to finish the work in the east bound lanes.
