Secondary Slide Occurs at mm 10.9
CHATTANOOGA, Tenn. - Construction crews with Charles Blalock & Sons continued working to remove lose rock and other material from the upper western side of the slope. Crews are preparing to install 40 ft. long rock anchors at the site on Wednesday. A geotechnical engineer worked alongside crews to determine bolting locations on the slope face today. The contractor completed hauling the remaining slide debris from the roadway surface on Saturday. Crews then extended the pad for the 275 lb. crawler crane to the east on Sunday and Monday in order to reach the work area on the eastern side of the slope. The contractor plans to resume drilling Wednesday in preparation for a scheduled blast on the eastern side of the slope on Friday, January 22, 2010.
