Field Value
Title Jackhammer Crew
Description Here jackhammer crews are at work on the upper portals of the pumping plant tunnels. Excavation of rock in these discharge tunnels was bid by CBI at $10.00 per cubic yard. In the gravity plan for irrigating the Columbia Basin there was one place that required two parallel tunnels 16 miles long and 32 feet in diameter thru solid basalt rock harder than granite, and to be lined with concrete. The total length of tunnels in the gravity plan was 33 miles, at a cost of about $105,000,000.
