LowSpan is a specialized precast concrete solutions provider based in Michigan, renowned for our innovative and high-performance structures designed for culverts, bridges, and tunnels. We offer two primary product lines: the LowSpan system and the MegaBox® system.

The LowSpan system is a three-sided, pre-stressed top slab, reinforced precast concrete structure ideal for culverts, bridges, and tunnels. This design provides a low-profile solution with a minimum inside rise of 3 feet and spans up to 60+ feet, accommodating various site conditions and loading requirements.

MegaBox® is a four-sided, clamshell-style precast concrete box culvert system featuring pre-stressed top and bottom slabs. This design allows for rapid installation and is particularly effective in areas with poor soil conditions, as it distributes loads evenly and reduces the need for deep foundations.

LowSpan's commitment to engineering excellence and adaptability makes it a trusted partner for agencies and contractors seeking efficient, durable, and environmentally compliant infrastructure solutions.
