Oversized loads were on Kihei and Maalaea roads Friday with the movement of large wind turbine components for Kaheawa Wind II from storage at the Maui Research & Technology Park.
The transport by Tri-Isle will continue until mid-March, but only during daylight hours.
The oversized trailers will be escorted by police. The vehicles generally can be expected to travel at safe speeds with the regular flow of traffic.
Other motorists are asked to be cautious.
Movement will depend on weather at the site above Maalaea but should probably occur four or five days a week, a news release said.
Kekoa Kaluhiwa, director of external affairs for First Wind, said: "While we hope to keep traffic disruptions to a minimum, we thank the Kihei and West Maui communities for their understanding and patience during the process."
The transport route begins at the R&T Park, turns west on Piilani Highway, continuing west on North Kihei Road to Honoapiilani Highway to the project site.
The total trip time for each component is expected to be about 20 minutes. No extended road closures are anticipated.
Questions regarding the delivery route and schedule should be directed to Leo Arsenberg of Tri-Isle Inc. at 244-1800.
Kaheawa Wind Power II will consist of 14 wind turbines, capable of generating 21 megawatts of energy, enough to power about 7,700 Maui homes.
