HART Completes 4 Miles of Elevated Guideway

The Honolulu Authority for Rapid Transportation (HART) has achieved another milestone with the completion of four miles of the system's elevated guideway.

Crews have now constructed more than 170 spans.  A span is the portion of the guideway between two support columns. The four-mile mark is along Farrington Highway in Waipahu. To date, 290 foundations have been completed and 204 columns have been built, as the guideway makes its way through Waipahu. 

The guideway segments are cast at the project's casting yard in Kapolei, and a single span requires about 12 segments. Each segment weighs about 50 tons. 

 "We continue to make progress on the construction of our rail project," said HART Executive Director and CEO Dan Grabauskas.  "Safety is our top priority, and we want to thank the public for their patience, and for driving safely through our construction zones."
