Representing an investment of more than $50 million by Union Pacific, the structure improves operating efficiency, supports growth in Union Pacific's customers' businesses and delivers increased freight capacity on the railroad's busy corridor linking Chicago to the West Coast.
"The new Kate Shelley Bridge enhances our long-term ability to improve operational efficiency and customer service," Young said. "Congratulations to all Union Pacific employees and contractors who worked on what is truly a modern-day engineering feat."
"It is only fitting that the new bridge is given the name of the structure it replaced, Kate Shelley, to honor a person who helped save so many lives when she was able to help warn an oncoming passenger train that a bridge had washed out during a stormy night 1881," Young added.
Built between 2006 and 2009, the new bridge was constructed to handle heavy trains such as coal and grain. The two tracks, 20 feet apart, are set on a ballast deck that is supported by reinforced concrete towers and steel piles. Two trains can operate on the bridge at the same time at the maximum speed of 70 mph. The first train operated over the bridge August 20.
OCCI, Inc., based in Fulton, Mo., was the contractor for the project and Omaha-based HDR Engineering Inc., provided the engineering for the bridge construction.
Since 1997, Union Pacific has invested more than $1 billion in Iowa in branch line upgrades, east-west corridor capacity improvements, ethanol and grain related projects, communication and signal improvements, and major projects such as the new Kate Shelley Bridge.
