Kate Shelley High Bridge: Iowa Time Machine May 19, 1901

Iowa Time Machine ⏰: On May 19, 1901, Kate Shelley was present at the dedication of the Boone Viaduct. The longest double-track railroad bridge in the world, built from 1899 to 1901, the viaduct was later renamed the Kate Shelley High Bridge. A new high bridge, opened in October of 2009, was built beside the old bridge and is also known as the Kate Shelley High Bridge.

Shelley’s story belongs to the age when railroads defined both danger and progress across the Midwest. In 1881, as a teenager, she warned an approaching train after a storm wrecked the bridge near Moingona, an act that made her a local hero and later one of Iowa’s most celebrated figures. By the turn of the century, railroads were building larger and stronger bridges to handle heavier traffic, and the Chicago and North Western Railway chose the Des Moines River crossing near Boone for a structure that reflected the scale and ambition of the railroad era.

At the time the Boone Viaduct was completed and dedicated, it was described as the longest double-track railroad bridge in the world, a claim that underscored both its size and the confidence engineers had in modern steel construction. The bridge soon became known as the Kate Shelley High Bridge, a name that tied the physical landscape of Boone County to her rescue of the passenger train two decades earlier.

In 2009, a new high bridge was built beside the old one, and it too was named for Kate Shelley, carrying her story into a new century of rail traffic. The newer structure opened in October 2009, while the original Boone Viaduct remained in place as a historic landmark and reminder of the railroad age. The bridge’s dual identity, as both working infrastructure and memorial, shows how Iowa has continued to preserve the connection between engineering achievement and local legend. #Iowa #OTD #History #Railroad #Transportation
