HDD Culvert Cleaning Proves Effective

By Jeff Griffin, Senior Editor | March 2010 Vol. 65 No. 3

Meeting with engineers, Harr began taking on culvert cleaning projects from large primary contractors. After his system proved effective in cleaning culverts with diameters to four feet and at distances exceeding 200 feet, the Alaska State Engineer asked Harr whether his system could address a collapsed section of the James Dalton Highway. That led to Ice Road Trucker highway project, completed November 2009.
