What is the HART Rail Guideway Mauka Shift?
The Mauka Shift refers to a plan to move a section of the rail guideway from the center of Dillingham Boulevard to the mauka side of the street. This mauka shift saves time and money for the Project by eliminating the need to relocate certain utilities.
Currently there is a complex web of electricity, water, sewer and fiber optics lines that run under Dillingham Boulevard. There are also two 138-kilovolt power transmission lines above ground on either side of Dillingham Boulevard. On the makai side, there are also 12- and 48-kilovolt power lines. For HART to move all of these power lines underground would be extremely difficult as there is not enough room to provide the clearances needed to service existing utilities. Moving the guideway to the mauka side of the street eliminates the need to bury all of the power lines on the makai side and avoids the need to move other existing underground utilities, thereby improving the Project schedule and reducing costs by approximately $150 million.
