Activity
Detailed guideway design

To alleviate worsening roadway congestion in Honolulu, HI, which is among the worst in the US, HART is constructing a nearly 20-mile grade separated rail along the most populated area of the island. Because the transit corridor is largely being developed in an urban environment, the system is designed as an elevated structure for nearly the entire length of the alignment. For phase 3 of this project, SYSTRA is the designer and engineer of record for most of the five-mile elevated guideway in some of the most congested areas of Honolulu.

Typical span lengths range from 65 to 150 feet and one longer pair of 165-foot 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.
