The Unofficial
I-26 Construction
Madison County
North Carolina

A trackhoe keeps several dump trucks busy carrying undercut material out of this large and deep construction site. Undercut removal and disposal is a big challenge on these projects; it must be removed before anything else is done in the area and disposed of in a safe location, then rock is brought in and used to build a base for the fill and drainage systems. When over 30'-50' of material has to be removed, though, disposal of it can become difficult. Two waste sites for disposal of this material were made available for both A-10C and A-10D to help the contractor find a suitable location for the undercut.
