Precast Bridges and Structures for Grade Separation

Our CON/SPAN and BEBO structures are commonly used for grade separations. These systems are strong enough to carry massive off-highway and railroad loads and are available in shapes to accommodate critical clearance boxes.

Precast / Prestress Bridges for Heavy Loading Applications

CON/SPAN, BEBO, and Contech Prestress structures can easily accommodate Heavy Equipment Transport (HET) loading and maintenance requirements and set-in-place installation makes them a great solution for stream crossings.

Precast Structures for Taxiway Bridges and Runway Extensions

Specifying precast bridges and underground structures for airport applications offers a number of advantages for airport designers. Fast installation shortens work schedules and disruptions, while the large load-carrying capacity of their arch is perfectly suited for high-load airport applications. CON/SPAN bridges have been used for airport taxiway underpasses and overpasses (easily bearing 747s, Antanov 225, and other heavy aircraft), runway extensions, as well as glycol storage tanks for de-icing solvents and tunnels for baggage tugs.
