YourToyTrains is proud of the Union Pacific Railroad. In 1904 the Lucin Cutoff was built- a huge bridge and causeway across Great Salt Lake. The bridge was replaced in 1959, but because the Great Salt Lake is between two faults the bridge has sunk 15 feet since its completion. Water is not able to flow north to south in the lake- blocked by the 20 mile bridge/causeway. Since three rivers flow into the southern part of the Great Salt Lake (Below the bridge), that water is less salty. Water north of the bridge is more salty. This unnatural balance is impacting brine shrimp and causing other environmental consequences. Union Pacific Railroad is now rebuilding the causeway with a 180 foot bridge to allow water to flow and adding adjustable earthen berms to restore the Great Salt Lake's health. The railroad is happy, the State of Utah is happy, and the Friends of the Great Salt Lake are happy. Great news all around!
