Prefabricated Bridge Units

Prefabricated Bridge Units for Coordinated Installation

Fort Miller’s Prefabricated Bridge Units (PBUs) provide a coordinated precast bridge-system solution for projects that need durable construction, efficient installation, and minimal disruption to the traveling public.

Custom-designed for site-specific conditions, PBUs can span up to 126 feet and accommodate skews exceeding 45 degrees. Units can also integrate precast piers, abutments, pedestals, barriers, and approach slabs to help project teams coordinate more of the bridge system through a single precast strategy.

A Faster Path to Bridge Replacement

Prefabricated bridge systems move key fabrication work off-site so the structure can be delivered ready for installation. For projects with limited closure windows, overnight work, weekend construction, or complex traffic-maintenance requirements, PBUs can help reduce the duration of field operations.

This approach is especially well suited to:

• Accelerated bridge construction
• Bridge replacement projects
• Projects with short closure windows
• Complex geometry and skewed structures
• High-traffic corridors
• Projects requiring coordinated precast components

Integrated Precast Components for Complete Bridge Systems

Fort Miller can coordinate PBUs with a range of precast bridge components, including:

• Precast piers and abutments
• Pedestals
• Bridge barriers
• Approach slabs
• Deck components
• Other custom bridge elements

By considering the system together, project teams can better align design, fabrication, transport, installation sequencing, and field coordination.

Designed for Site-Specific Conditions

No two bridge projects are identical. Fort Miller works with owners, engineers, and contractors to develop prefabricated bridge units around required span lengths, skew, geometry, loading, access, transportation, and construction schedules.

The goal is a durable precast solution that fits the project—not a one-size-fits-all component.
