NSBA Recognizes Eight Top Bridges--and One Remarkable DOT--for 2024

 

Innovation abounds in the steel bridge industry, but eight recent bridges rise above the rest.

The American Institute of Steel Construction and the National Steel Bridge Alliance are recognizing these eight bridges with 2024 Prize Bridge Awards--the structural steel industry’s highest design honor for bridges.

"Steel bridges have connected American communities for centuries," said NSBA Senior Director for Market Development Jeff Carlson, PE. "This year’s Prize Bridge Award winners continue that proud tradition and showcase the innovation--at all scales, from showcase bridges to local lifelines--that will keep Americans moving for centuries to come."

This year, NSBA debuted a brand-new award that recognizes the driving force behind extraordinary bridges: extraordinary owners, whose vision and dedication to the public keep America moving.

The inaugural Owner of the Year award goes to the Texas Department of Transportation. "TxDOT isn't just implementing best practices for designing and building steel bridges--it is defining how an owner can maximize the potential of steel," Carlson said. "Recent projects like the remarkably economical Brazos River Bridge demonstrate how TxDOT's longstanding investment in steel bridge research is paying dividends for Texans, today and tomorrow."

There is one remaining 2024 Prize Bridge Award to present: the Bridge of the Year. The finalists are indicated below; the teams behind those bridges will present to the industry at the World Steel Bridge Symposium at NASCC: The Steel Conference on Wednesday, March 20. Conference participants will select the winner live!

Without further ado, here are the 2024 recipients of the National Steel Bridge Alliance Prize Bridge Awards. Press photos are available for download here.
