OCCI, Inc. constructed a new double-track bridge, 2550′ long and 180′ above the Des Moines River in Boone, Iowa adjacent to existing Kate Shelly Bridge, located only 90′ away. The new bridge more adequately accommodates the heavier loads and faster travel (70 mph) of today’s railroad industry. The original bridge was completed in 1901, and had a speed limitation of 20 mph.
