A poll conducted in May and paid for by the city shows that 57 percent of Oahu residents supported the $5.3 billion rail project.
Of about 900 people polled throughout all nine City Council districts, 40 percent opposed the project, while 3 percent had no opinion.
The results were released today.
The poll was conducted by Qmark Research, with a price tag of about $24,000, said Mayor Peter Carlisle.
It was conducted from May 9 through May 20, and has a margin of error of 3.27 percentage points.
