UPRR Harrisburg

After 106 years of service, the mainline Union Pacific Railroad bridge across the Willamette River at Harrisburg is being replaced. The current bridge is a 908 ft. steel truss bridge. CJA was selected by Hamilton Construction to install 18 each 2.2-meter diameter drilled shafts up to 140 feet deep using the 3-meter Leffer oscillator. All of the work is being accomplished during live rail traffic and the shafts are being installed off of a trestle.

Work was completed in January of 2014.
