AUGUSTA (AP) – Maine voters on Tuesday gave their approval to a $29.7 million bond package to pay for improvements to roads, bridges, dams, landfills and other public facilities.

It was the final part of a borrowing package worth up to $295 million that the Legislature voted in 2007 to send to voters in three separate pieces. The previous two portions were approved.

Supporters said the bonds, if authorized, would leverage another $29.8 million in other funds. But the bonds would also cost an estimated $8.6 million in interest.

With 40 percent of precincts reporting, the bond package had the support of 59 percent of voters, while 41 percent opposed the borrowing proposal, according to unofficial returns.

Of the total borrowed, $23 million would be for transportation projects, including highway and bridge improvements, passenger and freight rail, transit and bus facilities, ferry, port and airport improvements and bicycle and pedestrian trails. The bonds would also pay for reconstruction of a bulkhead and wharf at the former Coast Guard facility in Portland. Funds would be earmarked for state fish hatchery improvements and rehabilitation of dams.

The remaining money would go to cleanups of hazardous waste sites, replacement of malfunctioning septic systems, landfill cleanups and air pollution monitoring equipment.
