Pacific Canyon Railroad Bridge
Eureka County, Nevada
Geotechnical Observation and Testing
The project was located southeast of Palisade, Nevada, where the westbound railroad tracks cross the Humboldt River before entering a tunnel. A westbound freight train had derailed and damaged the approximately 100-year-old bridge at this location. The railroad had replaced the damaged bridge with a new 7 span precast concrete trestle supported on HP14 x 89 pile bents. The pile load was about 112 tons. Converse performed a limited geotechnical investigation to gather information for the design of the new bridge, specifically whether the new piles could be driven or if drilling and socketing techniques would be required.
