Post-tensioning is a cost-effective form of construction that produces high-quality bridges over a wide range of conditions and span lengths including highway alignment. Bridge structures constructed using post-tensioning has high intrinsic durability and an expedited construction process with minimal impact on the human and natural environment. Further benefits of structures constructed using post-tensioning is the method's ability to limit cracking, reduce structural depth, the ease of accommodating curved roadway alignment and low maintenance costs. Amongst all these benefits, is the aesthetic expression that comes with these post-tensioned structures.

Cast-in-place cantilever construction has become the preferred method of building long-span concrete bridges and concrete arches with the assistance of temporary towers and stays. It is a proven cost-effective process of building spans ranging from 200-feet (60 m) to more than 1,000-feet (300 m). It has been used to cross major bodies of water, deep mountain canyons, and densely populated urban areas. Further to this, post-tensioning can be used effectively to build bridges on alignments that are curved in plan.

Post-tensioned superstructures can be constructed quickly and without touching the land or water below the bridge. They are a relatively low impact structural system and optimal solution. For longer spans (commonly up to 300-feet or more), shallower girder depths, and continuously curved superstructures, post-tensioning offers ductility and seismic performance as well as superior aesthetics to modern precast designs. Post-tensioning also provides more flexibility in the layout of span lengths, bent configurations and roadway geometrics than precast I-girders or reinforced concrete box girders.
