Callender-Hamilton Bridges* are modular prefabricated time tested bridges that have been manufactured since the 1940's. The bolted truss structure is designed primarily for permanent applications. Clear span lengths can range from 30 meters to 150 meters. Road widths are one, two, three, or more lanes. Concrete, steel orthotropic, steel open grate, or timber decks are available. All components are hot dipped galvanized to minimize weathering. Callender-Hamilton Bridges* can be assembled on side of a gap and rolled out across the gap until it reaches the far side. They can also be erected by other methods. Callender-Hamilton Bridges* are designed in accordance with United States, Canadian, and British standards for vehicular and railway loads.

Two 110 m clear span bridges were recently installed on the Trans Labrador Highway. The bridges are designed for two lanes of full highway truck loading.
