It was an honor to collaborate with SW Bridge Engineers, LLC on this video project. Watch the full version here: https://youtu.be/W32XkJ-gqb8
Constructed in 1902 by Milwaukee Road, this railroad bridge is the final outdated structure on CRANDIC’s Amana Subdivision south of Cedar Rapids, Iowa. It serves as a vital link in CRANDIC’s rail system. On average, 90,000 railcars — including over 27,000 carrying hazardous materials — cross the Iowa River bridge each year. Replacing it ensures decades of safe, reliable operations, supporting efficient rail freight transportation for industries in and around Cedar Rapids.
The replacement project will:
• Raise the new bridge by 30 inches, exceeding the 100-year flood height.
• Lengthen and widen the through-truss span.
• Increase load capacity to 286,000 pounds, surpassing the existing bridge’s design limits.
