New bridge to improve safety along Highway 44 near Platte

PLATTE, S.D. (Dakota News Now) - A major bridge project in South Dakota aims to make a key highway route safer and more reliable for decades to come.

The state is replacing the Platte-Winner Bridge, which carries Highway 44 over the Missouri River.

State leaders gathered on Thursday for a groundbreaking ceremony.

Since opening in 1966, a recent study has revealed that landslides along the highway have led to millions of dollars in repairs.

The new bridge will be eight feet wider, with shoulders to give drivers more room.

It’s also being designed to last 100 years.

“As the longest bridge in South Dakota, the Platte-Winner Bridge plays an essential role in keeping our state connected,” said Governor Larry Rhoden. “With a 100-year service life, this 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.”

“For the past 60 years, the Platte-Winner Bridge has served as an essential link connecting communities in South Dakota and across the region,” said Senator John Thune. “This vital infrastructure project will help ensure it continues to keep our communities and businesses connected and remains a safe crossing for all who rely on it to travel across our state.”

Drivers won’t have to find a different route during construction because the existing bridge will stay open, although some temporary lane closures are possible.

The project is expected to last from 2027 through 2031, and construction will be handled by Ames Construction of Burnsville, Minnesota.
