Live Time-lapse Camera Now in Place
CHATTANOOGA – The Tennessee Department of Transportation is now providing a live look at the work to clear a major rockslide along U.S. 64 in Polk County. A live time-lapse camera is now available on TDOT’s U.S. 64 Rockslide web page (http://bit.ly/1Tlc8m).
On Tuesday, November 17, crews with contractor Charles Blalock & Sons, Inc. worked to mobilize equipment to the site while TDOT geotechnical engineers and representatives from Blalock spent the majority of the day ascending and investigating the upper reaches of the rock slope around the perimeter of the slide area. The inspection was conducted to identify critical areas of the rock slope where the contractor will first need to remove loose rock and unstable debris.
Once the debris and rock is removed construction crews will begin trim-blasting operations to bring down the remaining rock overhangs that present an immediate hazard to workers. Tuesday’s inspection also allowed the contractors and TDOT personnel to better assess the condition of the slope and identify the areas where the 40’ long rock bolts will be drilled and cemented through the slide plane in order to help further stabilize the slope.
Today, November 18, crews are continuing to survey the slide area and are working to clear some vegetation from the slope. Removing the vegetation will improve safety for crews that will begin scaling operations on the slope in the coming days. It will also allow geotechnical engineers to get a better look at the condition of the cracks in the rock and the planes along the slope.
U.S. 64 in Polk County is 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 expected to take at least eight weeks.
Motorists traveling to the area from Chattanooga or Cleveland should take I-75 North to Exit 60 (SR-68, Sweetwater) and follow SR-68 South through McMinn County and into Ducktown in Polk County. Those traveling from North Carolina are advised to take US-74 to SR-68 North at Ducktown through McMinn County then onto I-75 at Sweetwater in Monroe County.
