Abstract: At approximately 9:40 a.m. on September 30, 2011, Employee #1, a finish roller operator, was working with a work crew doing asphalt patching in the outside lane of two northbound lanes. The employee had been observed standing on the east side of the barricaded lane, however there were no witnesses to the incident nor could any determination be made as to why the employee was in that position. Employee #1 was struck and killed by the right rear tandem wheels of a fully loaded semi trailer which was backing into position. The employee was wearing a high visibility work vest and the semi trailer had an audible reverse warning device.
