Construction engineers finishing up the country’s longest cathedral-arch bridge in a tough, rocky patch of northern Nevada say they have found a new way to capitalize on the slow-and-steady power that strand jacks provide.
C.C. Myers Inc., Rancho Cordova, Calif., is using a dozen of the 85-ton jacks fabricated by Milwaukee, Wis.-based Enerpac to lower falsework for the 1,722-ft-long Galena Creek Bridge. The project is part of the $393.3-million final leg of an 8.5-mile Interstate 580 extension between Reno and Carson City being built by Dickinson, N.D.-based general contractor Fisher Sand & Gravel Co. The 295-ft-tall, cast-in-place concrete and steel-reinforced bridge consists of two parallel, 62-ft-wide, three-lane structures with 689-ft-long center spans.
