The goal of this project was to repave 14 miles of Interstate 5 between Hugo and Glendale, Oregon, construct one 2.8-mile climbing lane and make other safety improvements.
Drilling and blasting was located at the summit of the 2.8-mile climbing lane. The overall height is over 100 vertical feet, an average horizontal depth of 0 at the top of slope and 30 feet at the toe of slope, and a total length of approximately 1,000 feet. The blasting consisted of over 29,000 linear feet of perimeter controlled blast holes and 30,000 cubic yards of rock. McCallum Rock Drilling provided up to three rock drills. We blasted once per night and up to twice a week.
