DESIGN-BUILD
Typical Span Length: 65 to 150 ft (20 to 46 m) and two 165 ft (50 m) continuous spans.
The Hart Metro, Contract 3, consists of 5.1 miles of elevated guideway for a new light rail system. It includes typical span lengths ranging from 65 to 150 ft (20 to 46 m) and one longer pair of 165 ft (50 m) continuous spans.
The substructure, designed for high seismic demand, consists of single reinforced concrete piers supported on mono-drilled shafts. The superstructure is constructed using precast segmental technology, with the superstructure erected span-by-span with an overhead gantry.
