The Kate Shelley High Bridge, officially called the Boone Viaduct when it was completed in 1901, was one of the highest and longest double-track railroad bridges in the United States. It is located approximately 3 miles (4.8 km) west of Boone, Iowa.
It was nicknamed for the Iowa railroad heroine, Kate Shelley, also spelled Shelly. In 1881, when she was 17 years old, Kate Shelley risked her life to warn a passenger train by crossing the Des Moines River Bridge near Moingona at night, during a thunderstorm. Her goal was to warn the passenger train that the next bridge was out. That train had already been stopped. She then led rescuers to two men still in the swollen, flooded Honey Creek near her house, and they were saved. Her bravery was heralded in many newspapers.[2]
The bridge was designed by George S. Morison for the Chicago & North Western Railway and was constructed from 1899 to 1901.[3] It stands 185 feet (56 m) above the Des Moines River and is 2,685 feet (818 m) long. The bridge was never officially renamed for Kate Shelley, but there were many commemorations there to honor her as if it carried that name. Gradually it became better known as the Kate Shelley High Bridge, or just the Kate Shelley Bridge, and the popularity of the Boone Viaduct name faded.
History
By the mid-1950s, traffic on the bridge was limited to one train at a time.[4] In 1986, some of the bridge towers were damaged in a wind storm.[4] Union Pacific Railroad is the current owner of the bridge, and starting in 2001, they undertook an inspection and repair program; this resulted in both tracks being opened again, but with a 25-mile-per-hour (40 km/h) slow order.[4]
The bridge is located on an east/west Union Pacific main line—the Overland Route[5]—connecting Chicago to the west coast.[6]
New Bridge
From 2006 to 2009, Union Pacific constructed a new double track concrete and steel bridge next to the old span.[7] During construction, the bridge was lengthened 160 feet (49 m) to the east due to instability of the bank caused by heavy rains in Spring 2008; this delayed completion by at least eight months.[8] The bridge opened to traffic on August 20, 2009, when the Union Pacific ran its first train across the new span.[7] The UP officially named the new viaduct the Kate Shelley Bridge. The new bridge can handle two trains simultaneously at 70 mph (110 km/h), and at 2,813 feet (857 m) long and 190 feet (58 m) high,[7] the new bridge is longer and slightly taller than the original. The original bridge was left in place.
Name Confusion
In addition to the Boone Viaduct (completed 1901), a.k.a. the Kate Shelley High Bridge, and the Union Pacific Kate Shelley Bridge (completed 2009), at least two other bridges have been occasionally called the Kate Shelley (Shelly) bridge. The bridge at Moingona that Kate crossed was sometimes referred to as the Kate Shelly Bridge before the Boone Viaduct was complete. A new steel bridge was built to replace the old wooden Moingona one in 1894. The small stone bridge over Honey Creek near her house, where the pusher engine crashed, was also occasionally called the Kate Shelley (Shelly) Bridge.
There were and have been many high trestles in Boone County, such as the Boone & Scenic Valley Railroad's Bass Point High Bridge.[9]
