Update 2/1/20

Kawela Stream Bridge
All of the piles at abutment 2 were installed and the area around them excavated in preparation for placement of the abutment footing. The test pile was installed at abutment 1. The remaining 7 pile locations were predrilled in preparation for driving.

Nanahu Stream Bridge
The temporary bypass road was opened to traffic on December 18, 2019 and traffic detoured around the existing bridge. KIWC potholed for the location of the waterline makai of the existing bridge. The waterline was found to be in conflict with the planned GRS abutments, initiating a redesign of the abutments. KIWC plans to begin excavation for the abutments when the redesign is complete, which is anticipated to be at the end of the month.

Off Site Activities
GPRM will begin casting the precast concrete bridge girders for both bridges.

Design Activity Look Ahead
The Design is complete, and the project is now in construction. The discovery of the exact location of the waterline at Nanahu Stream Bridge initiated a redesign of the layout of the bridge abutments.
