![Hart Metro, Contract 3 – Honolulu, Hawaii](https://www.systra.com/ibt/wp-content/uploads/sites/21/2022/01/systraibt_website-hart3-scaled.jpg)

## 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.
