The challenge

The challenge for the Alberici joint venture in the I-64 Daniel Boone Bridge Project was to design and construct a new bridge over the Missouri River that could accommodate the high volume of daily traffic and withstand seismic events and barge impacts. Additionally, the project required integrating a shared-use path for pedestrians and cyclists while maintaining traffic flow during peak travel hours. The team needed to ensure the bridge’s longevity, future capacity demands, and cost-effectiveness, all while adhering to a tight schedule and maintaining safety standards.

Challenge met

The Alberici team devised a comprehensive design-build solution in collaboration with MoDOT and design partner Burns & McDonnell. The team incorporated value-added improvements to accommodate future capacity needs and developed an economically efficient bridge design to reduce maintenance costs over its 100-plus years of service life. To maintain traffic flow, the team carefully managed construction activities to avoid long-term closures during peak hours. Self-performing nearly 75% of the project, Alberici employed watertight cofferdams to enable construction of piers in the dry, ensuring safety and quality throughout the construction process. The result was a state-of-the-art bridge that could handle high traffic volumes, provide a separate shared-use path, and withstand environmental challenges while offering an enhanced scenic experience for pedestrians and cyclists.
