Portland Maine METRO Bus: Hidden Routes Worth Trying
Portland, Maine's Greater Portland Metro bus system features several lesser-known routes that locals rely on for efficient daily commutes, including Routes 4, 7, 8, 9A, 9B, 21, 24A, 24B, and the Husky Line, which connect underserved neighborhoods, suburban areas, and key hubs like the Maine Mall and Portland Jetport without the crowds of popular lines like Route 1 or the BREEZ express.
Why These Routes Stay Under the Radar
These lesser-known routes thrive among Portland residents because they serve residential pockets and industrial zones overlooked by tourists fixated on downtown connectors. In 2025, Metro reported a 15% ridership uptick on these lines during weekdays, peaking at 1,200 daily passengers on Route 7 alone, compared to just 5% growth on high-profile routes. Local driver Maria Gonzalez noted in a 2024 interview, "Folks know Route 8's Peninsula Loop saves 20 minutes circling East End versus walking Congress Street."
Historical context dates back to Metro's 2020 restructuring, the biggest overhaul in 30 years, which extended these routes to boost frequency along outer corridors like Westbrook and Falmouth. By June 4, 2024, updates added Jetport service to Route 7, eliminating it from Route 5 to streamline mall access.
