The new span is scheduled to be built between 2027 and 2031, with the existing bridge remaining open throughout construction, said South Dakota DOT. It will not be removed until the new bridge is complete, the agency stressed.

Honoring a tradition from the original Platte-Winner Bridge dedication ceremony held in 1966, bands from Platte-Geddes High School and Winner Area High School performed at the groundbreaking, which hosted a bevy of federal, state, and local officials.
“As the longest bridge in South Dakota, the Platte-Winner bridge plays an essential role in keeping our state connected,” said Governor Rhoden in a statement.
“With a 100-year service life, this [new] bridge is a responsible investment in South Dakota’s transportation infrastructure. I am confident it will strengthen our economy and reinforce connections across our state and nation,” he added.
“For rural communities across south-central South Dakota, this Missouri River crossing is a vital lifeline that keeps supply chains moving, connects local producers to markets, and ensures families can safely reach key recreational areas,” noted Federal Highway Administrator Sean McMaster. “We’re proud to deliver real, lasting results that will enhance safety and support economic growth across this region for generations to come.”
