In 2024, NSBA debuted a brand-new award recognizing extraordinary bridge owners, whose vision and dedication to the public keep America moving. This year, the Owner of the Year award goes to the New York State Department of Transportation (NYSDOT).
Owner of the Year

National Winner: New York State Department of Transportation (NYSDOT)
The jury was also impressed by a second quick fix.
Major Span Category: one or more spans equal to or greater than 300 ft

National Winner: Hawk Falls Bridge Replacement Project, Carbon County, Pa. (Bridge of the Year finalist)
Owner: Pennsylvania Turnpike Commission, Middletown, Pa.
General contractor: Trumbull Corporation, Pittsburgh
Erector: Structural Services, Nazareth, Pa. *AISC associate member*
Structural engineer: Modjeski and Masters, Mechanicsburg, Pa.
Steel fabricator/detailer: High Steel Structures, Lancaster, Pa. *AISC full member, AISC-certified fabricator and erector*
Summary:
The new Hawk Falls Bridge is a three-rib steel deck arch designed not only to serve the traveling public but also to fit perfectly with the natural surroundings. The use of weathering steel for this location and a continuous multi-girder superstructure that minimizes expansion joints should result in a low-maintenance structure for many years to come.

National Winner: I-64 Kanawha River Bridge, Putnam County, W. Va. (Bridge of the Year finalist)
Owner: West Virginia Department of Transportation, Charleston, W. Va.
General contractor/erector: Joint venture of Brayman Construction, Saxonburg, Pa. *AISC full member*, & Trumbull Corporation
Structural engineer: HDR, Pittsburgh, Pa.
Steel fabricator/detailer: High Steel Structures, Lancaster, Pa. *AISC full member, AISC-certified fabricator and erector*
Summary:
The record span of the new I-64 Kanawha Bridge shows that thoughtful engineering and design considerations can result in the use of typical plate girder fabrication and construction for long spans, once thought to be unimaginable for this bridge type. This project shows that very long-span steel plate girders are a cost-effective, efficiently constructable solution for future projects of this size.
Medium Span Category: longest span equal to or greater than 140 ft but less than 300 ft

National Winner: Panther Creek Bridge, Klamath, Calif.
Owner: Caltrans, Sacramento, Calif.
General contractor/erector: Golden State Bridge Engineers & Contractors, Benicia, Calif. *AISC associate member*
Structural engineer: Caltrans, Sacramento, Calif.
Steel fabricator/detailer: Thompson Metal Fab, Vancouver, Wash. *AISC full member; AISC-certified fabricator*
Summary:
The tied-arch structure of the Panther Creek Bridge is an aesthetically pleasing solution that only steel can provide. While visually stimulating, the bridge solves functional issues by keeping substructure units out of the water below and limiting changes to the roadway profile.

Merit Winner: Broadway Viaduct Bridge Replacement, Nashville, Tenn.
Owner: Tennessee Department of Transportation, Nashville, Tenn.
General contractor/erector: Kiewit, Nashville, Tenn. *AISC-certified fabricator and erector*
Structural engineer: Gresham Smith, Nashville, Tenn.
Steel fabricator/detailer: W&W | AFCO Steel *AISC full member, AISC-certified fabricator and erector*
Summary:
The Broadway Viaduct Bridge Replacement project is a great case study for how only steel can be customized to provide a shallow superstructure that meets the vertical clearance requirements of obstructions below, with minimal disturbance to the bridge approach roadway.
Short Span Category: no single span greater than 140 ft

Owner: Missouri Department of Transportation, Jefferson City, Mo.
Summary:
The FARM Bridges Design Build Bundle project shows once again the cost-effectiveness that steel superstructures can provide in both the short-span and design-build environments. Coordination by all project stakeholders resulted in simplified fabrication and erection for 31 different short-span bridges across the state of Missouri.
Movable Bridge Category

Owner: New York City Department of Transportation, New York
Summary:
The precision and accuracy needed for the twin single-leaf bascules spans of the Unionport Bridge can only be accomplished with the use of structural steel. Additionally, another key feature of this project is the construction of the bridge within the site constraints of an incredibly tight urban environment.
Special Purpose Category

National Winner: Williams Crossing, Tulsa, Okla. (Bridge of the Year finalist)
Owner: Stonebridge Group, LLC, Tulsa, Okla.
General contractor: Crossland Construction Company, Tulsa, Okla.
Structural engineer: schlaic bergermann partner (sbp), New York
Steel fabricator: Hillsdale Fabricators, St. Louis *AISC full member, AISC-certified fabricator*
Detailer: Esskay Structures, Vienna, Va. *AISC associate member*
Consultant: ruby + associates, Bingham Farms, Mich.
Summary:
The Williams Crossing pedestrian bridge demonstrates yet another way structural steel elegantly meets transportation needs. The first-ever use of this stiffened-plate concept is the signature feature of this bridge, which can only result from great teamwork.
REHABILITATION Category

Summary:
One of the great aspects of steel bridges is the ability to rehabilitate, strengthen, and repair them to extend their service life for years to come. The Sherman Minton Bridge, originally constructed in 1962, is another example of a signature structure that can be expertly rehabilitated and strengthened. In this case, the project team used innovative construction methods to replace the hangers and strengthen the superstructure through various steel repairs.
