The Union Pacific Railroad crosses here at the Dry Canyon Bridge (Hotlum Trestle) near Lake Shastina, California.  The bridge was destroyed after the Lava Fire swept through here around June 30, 2021, causing a disruption in rail traffic.  In the span of one month the bridge was rebuilt.  Nine bridge spans were installed, while another nine were heat-straightened by a specialized contractor before being lifted back into place. Complete bridge reassembly required more than 700 new railroad ties, 58 tons of new steel and 1,140 track feet of ballast deck pans across the bridge.
