Lucin Cutoff
From Wikipedia, the free encyclopedia
The Lucin Cutoff was a railroad trestle which crossed the Great Salt Lake in Utah. Built by Southern Pacific Railroad between February 1902 and March 1904 across Promontory Point, it bypasses the original route through Promontory Summit where the Golden Spike was driven in 1869. By going west from Ogden, Utah across the lake it cut off 43 miles and avoided curvatures and grades. It was supplanted, and eventually replaced in the late 1950s with a parallel causeway built under contract by the Morrison Knudsen construction company.
