Who We Are

We're the transit providers that help Southern Mainers — workers, students, seniors, and others — get where you need to go. We provide more than 4 million trips each year in the Greater Portland region, to the Casco Bay Islands, and beyond.


During the pandemic, we’ve put in place proven COVID safety protocols and made an extra effort to keep you as safe as possible. Now, we're still requiring masks, but we're allowing full capacity to keep you moving as quickly, affordably, and sustainably as before.


By providing an alternative to automobiles, we also help reduce road congestion and air pollution—including the emission of greenhouse gases that cause climate change.
