Bridges honored for their innovative steel construction.
KANSAS CITY, Mo. (February 6, 2024) The American Institute of Steel Construction and the National Steel Bridge Alliance have recognized the Frederick Douglass Memorial Bridge, I-94 Second Avenue Bridge, Long Beach International Gateway Bridge and SR32 Bridge over Stony Creek with Prize Bridge Awards.
The Prize Bridge competition was first launched in 1928 by AISC to showcase the beauty of steel bridges. Winners are selected by a panel of judges who weigh each project’s use of structural steel from both an architectural and structural engineering perspective.
Frederick Douglass Memorial Bridge- Prize Bridge Award, Major Span Category
The Frederick Douglass Memorial Bridge serves as a gateway to the nation’s capital, increasing mobility and access to transportation to communities nearby. The bridge used grade 70 steel to provide extra strength where it needed between the arches while maintaining a consistent structure depth. HNTB provided program and construction management.
I-94 Second Avenue Bridge Network Tied Arch- Prize Bridge Award, Medium Span Category
The Second Avenue Bridge over I-94 is the first network tied-arch bridge in Michigan. The bridge connects the neighborhoods located on the north and south sides of Second Avenue and provides enhanced mobility for pedestrians, bicyclists and motor vehicles. HNTB designed the initial concept and oversaw construction.
Long Beach International Gateway Bridge- Prize Bridge Merit Award, Major Span Category
The Long Beach International Gateway Bridge is the first vehicular cable-stayed bridge in California, serving as a landmark for the region. The project team leveraged steel to provide a lightweight superstructure for an economical and innovative approach to seismic design. HNTB served as owner’s engineer and provided preliminary and final design.
SR32 Bridge over Stony Creek- Prize Bridge Merit Award, Short Span Category
SR32 Bridge Over Stony Creek is an innovative bridge that deployed a new approach for using press-brake formed girders that speeds fabrication and construction times while also saving money, enhancing resilience and accommodating spans of up to 300 feet. HNTB served as the structural engineer on the project.
