The project was begun with federal funding from the
Federal Highway Administration's Congestion Mitigation and Air Quality Program. With this being phased out after three years, it was partially replaced with continual support from the
Federal Transit Administration's Section 3507 Formula Funding Program, with the rest of the funding being provided by the towns serviced by the route. In addition, each town would be allocated one seat on the Metro board, with Portland's representation increased from five seats to eight, in order to maintain the city's having at least, but no more than, 50% of the seats on the board. Two months later, Breez and the
Amtrak Downeaster rail service established a partnership to promote public transportation options between Portland, Freeport and Brunswick. A pricing agreement was put in place, with a $3 one-way fare, a $27 ten-ride pass, and a $90 monthly option. In 2020, discussions began regarding a potential southern expansion to
Scarborough and
Saco. and a twice-daily round trip to
Bath Iron Works (BIW) was added in 2025. Senator
Susan Collins (
R) announced $1.8 million funding for public transport in Greater Portland in 2022, with the Metro using their portion to purchase four 35-foot, environmentally friendly buses to replace its aging fleet. The buses were launched in April 2023, with all rides being free on April 22 and 23 to celebrate the event. == Route ==
