CHATTANOOGA, TN (WRCB)- Construction crews with Blalock & Sons and Dyno Nobel (blasting subcontractor) set off a series of explosive charges Monday 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.
