The Lucin Cutoff is a 102-mile (164 km) railroad line in Utah which runs from Ogden to its namesake in Lucin. The line included a nearly 12-mile (19 km) long railroad trestle crossing the Great Salt Lake. Built by the Southern Pacific Company (SP) between February 1902 and March 1904, the cutoff bypassed the original Central Pacific Railroad route through Promontory Summit where the Golden Spike was driven in 1869. By going west across the lake from Ogden to Lucin it cut off 44 miles (71 km) and also significantly decreased curvature and grades. Built under the direction of SP chief engineer William Hood, a team of 3,000 SP workers worked seven days a week to build the line. By 1908, five passenger trains and seven freight trains were using the Lucin Cutoff in each direction daily. In 1942
