Friday, November 27, 2009 | 03:02 pm

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.

Drilling Operations Continue in Preparation for Blast Tomorrow
 
CHATTANOOGA, Tenn. – Workers with Charles Blalock & Sons Construction continued assembly of the 275-ton crawler crane and the construction of a crane pad on the west end of the project as blasting crews began drilling an outcropping of large rock formations in preparation of spot blasting operations that are scheduled to take place tomorrow. The contractor also hauled in approximately 200 tons (ten truck loads) of aggregate on the east end of the project which will be spread across US-64 in a 2’ to 3’ thick blanket and serve as an energy dissipater for falling rocks. The blanket is intended to absorb the energy of the falling rock and reduce the distance which they would otherwise travel.

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.

Video of the slide is available on the TDOT web site at http://www.tn.gov/tdot/US64rockslide/.
