CHATTANOOGA, Tenn. - Workers with rockslide removal contractor Charles Blalock and Sons on Friday, November 27 constructed an aggregate base pad for a 275 ton crawler crane on the west side of the rockslide while crews continued to remove loose rock and debris from the slope. The contractor also installed erosion and sediment control measures to prevent runoff at the site.
US-64 in Polk County continues to be closed at mile marker 17.6 due to a major rockslide near the Ocoee 2 Dam. A portion of Little Frog Mountain slid into the roadway on November 10, 2009. The project to remove the rockslide debris and repair the roadway is underway and expected to take at least eight weeks.
CHATTANOOGA, Tenn. - Construction crews with Blalock & Sons and Dyno Nobel (blasting subcontractor) set off a series of explosive charges this morning to dislodge an outcrop of large boulders that were positioned immediately above the main slide area. The boulders, ranging in size from 3’ to approximately 15’ in diameter, were dislodged with the blast and harmlessly fell down the slope to the roadway below. Construction crews continued assembling the 275-ton crawler crane on the west side of the slide in preparation of scaling operations that are set to begin on the west side of the slide area this week, weather permitting. The contractor plans to suspend work on Thursday for Thanksgiving Day but will resume work on Friday.
