Late on the night of March 14, 2019, large chunks of ice pressed against each other near the mouth of Iowa's Turkey River, forming a dam and causing the river to rise by six feet in mere minutes. Five spans of the bridge on CP's Marquette Subdivision main line across the river were lifted as a result and toppled into the icy water, leaving a 400-foot gap.
On March 27, with all safety inspections completed, CP train 691, an empty potash train bound for Saskatchewan, eased across nine newly installed spans over the Turkey River. What happened in between, during those mere 12 and a half days, was an astonishing engineering achievement. It is a testament to CP's strength and diversity and worthy of pride and celebration.
