Mid-Hudson Bridge

As the Mid-Hudson Bridge approaches its 100th anniversary in 2030, the importance of rehabilitating its aging infrastructure cannot be overstated.

A critical component of this project is the use of lightweight cellular concrete to infill the existing viaduct structures, which offers significant advantages in enhancing structural support while minimizing disruptions to traffic, particularly during peak travel times.

The flowable nature of this material allows for easy placement in challenging areas without the need for extensive equipment movement, ensuring that traffic flow remains largely uninterrupted. By utilizing a simple 3-inch hose system positioned along core holes in the viaducts, we can efficiently fill each section with cellular concrete, providing the necessary volume with a minimal physical footprint. This approach not only supports the structural integrity of the bridge but also exemplifies how lightweight cellular concrete serves as an optimal solution in complex infrastructure projects, balancing the demands of safety and accessibility for the traveling public.
