Portland, Maine's public transportation system is operated primarily by Greater Portland Metro (METRO), which provides 13 local fixed-route buses serving Portland, South Portland, Westbrook, Falmouth, and Gorham, plus express routes to Yarmouth, Freeport, and Brunswick, with daily ridership of approximately 8,500 passengers as of spring 2026. The system connects to intercity transportation including the Amtrak Downeaster at Portland Transportation Center, Concord Coach Lines, Greyhound, and Casco Bay Lines ferries, creating a multimodal network that moves over 2.1 million passengers annually across Cumberland County.
Core METRO Bus Network Overview
The fixed-route bus system forms the backbone of Portland-area transit with routes designed to connect residential neighborhoods to employment centers, shopping districts, and transportation hubs throughout Greater Portland. METRO operates service seven days a week, with peak-frequency routes running every 15-20 minutes during weekday rush hours and reduced weekend service starting as early as 6:00 AM on Sundays.
- Route 1: Congress Street Corridor - High-frequency service connecting Downtown Portland to South Portland Maine Mall
- Route 2: Forest Avenue - Links Westbrook to Downtown Portland via Forest Avenue
- Route 4: Brighton Avenue - Serves Westbrook community college and residential areas
- Route 5: Worthley Center - Connects Portland's East End to North Portland
- Route 10X: Express to Yarmouth/Cumberland Mills - Peak-only commuter service
- Route 11X: Express to Freeport/Brunswick - Daily express with limited stops
- Route 28: South Portland/Biddeford Connection - Links to BSOOB transit system
Each bus in the METRO fleet features modern accessibility equipment including wheelchair lifts, bike racks holding two bicycles, and real-time GPS tracking visible through the MetroTracker mobile app. The agency recently added six new compressed natural gas buses in March 2025, reducing emissions by 34% compared to the previous diesel fleet.
Fare Structure and Payment Options
Portland Maine transit uses a simplified fare system that makes boarding quick and affordable for all riders, with cash fares set at $2.00 for local routes and $3.50 for express routes as of January 2026. Transfer policy allows free transfers within 90 minutes of initial boarding when using swipe cards or mobile payment, encouraging multimodal trips across the network.
- Adult Cash Fare: $2.00 local / $3.50 express
- Reduced Fare (seniors 65+, disabled, Medicare cardholders): $1.00 local / $1.75 express
- Youth Fare (ages 7-17): $1.00 local / $1.75 express
- Children 6 and under: Free with paying adult

Payment acceptance includes exact cash**, SwipeCard debit cards, the METRO mobile app (Apple Pay/Google Pay compatible), and UMLR Pass for University of Southern Maine students who ride free with valid ID. The agency announced proposed fare increases effective August 1, 2026, which would raise adult local fares to $2.25 after three public hearings held in April 2026.
Regional Transit Connections and Partners
Around Portland Maine, multiple transit agencies operate coordinated services that extend mobility beyond METRO's core coverage area, creating an integrated regional network. BSOOB (Biddeford Saco Old Orchard Beach Transit) connects southern York County communities with daily service to the Maine Mall and downtown Portland, while South Portland City Bus provides localized circulation with three routes serving the mall, waterfront, and residential neighborhoods.
| Transit Agency | Service Area | Key Destinations | Daily Frequency |
|---|---|---|---|
| Greater Portland METRO | Portland, South Portland, Westbrook, Falmouth, Gorham | Downtown, Maine Mall, USM, Jetport | 13 local + 4 express routes |
| BSOOB Transit | Biddeford, Saco, Old Orchard Beach | Old Orchard Beach, Maine Mall, Portland | Every 30-60 min weekdays |
| South Portland City Bus | South Portland | Maine Mall, Waterfront, Cape Elizabeth | 3 routes, 45-min frequency |
| Casco Bay Lines Ferry | Casco Bay Islands | Peaks Island, Long Island, Bailey Island | 12 daily ferries summer, 6 winter |
| Amtrak Downeaster | Boston to Brunswick | Freeport, Brunswick, Boston North Station | 5 daily trains each direction |
| Concord Coach Lines | Portland to Boston/NYC | Logan Airport, Boston South Station, NYC | 12 daily buses to Boston |
The Portland Transportation Center at Thompson's Point serves as the primary multimodal hub, combining METRO bus connections, Amtrak Downeaster rail service, Concord Coach Lines intercity buses, and Greyhound terminals under one roof with real-time departure boards and heated waiting areas. This facility handled 487,000 passengers in 2025, representing 23% growth from 2023 pandemic recovery levels.
Casco Bay Ferry Service Integration
Casco Bay Lines operates the iconic ferry system connecting downtown Portland's Maine State Pier to seven inhabited islands in Casco Bay, providing both commuter transportation and tourist access to the "Calendar Islands". Peak summer service includes 12 daily departures to Peaks Island (the most popular destination with 1,200 year-round residents), while winter schedule reduces to six daily trips.
Ferry fares are separate from METRO bus fares but integrate through the regional pass program: adult one-way to Peaks Island costs $4.50 ($9.00 round-trip), with reduced fares of $2.25 for seniors and youth. The ferry terminal is located just two blocks from Monument Square, making it easily accessible via METRO Routes 1, 4, and 5 for riders connecting from the broader metropolitan area.
Accessibility and Special Services
Portland Maine's public transit prioritizes universal accessibility with 100% of METRO buses equipped with wheelchair lifts and priority seating, meeting ADA requirements since the original fleet renewal in 2018. METRO Paratransit service (called MetroPlus) provides door-to-door reserved transportation for riders unable to use fixed-route buses due to disability, operating within 3/4 mile of regular routes with advance reservation required.
MetroPlus reservations must be made one day ahead by calling 207-774-3221 between 7:30 AM and 5:00 PM, with fare set at $5.50 per one-way trip (compared to $2.00 for fixed-route). In 2025, MetroPlus served 89,400 trips across Cumberland County, representing 4.2% of total regional transit ridership. New accessibility improvements installed in February 2026 include tactile platform warnings at Transportation Center and enhanced audio announcements on all buses.
Upcoming "Transit Together" Plan Changes
Regional transportation officials adopted the "Transit Together" roadmap on January 26, 2023, with full implementation expected between 2026-2028 after agency approvals. This comprehensive plan addresses historical fragmentation by proposing a unified regional brand, redesigned route network, and technology integration across all Cumberland County transit operators.
Key goals of the transit redesign include establishing a high-frequency corridor along Congress Street with buses every 10 minutes during peak hours, creating more direct connections between Monument Square, the Transportation Center, and ferry terminal, and focusing frequency upgrades on South Portland routes serving transit-reliant populations in high-density areas. Implementation timeline shows Congress Street corridor improvements beginning fall 2026, with full network redesign launching January 2028 pending legislative funding approval.
Ridership Trends and Service Quality Metrics
Portland Maine transit ridership rebounded strongly after the pandemic, reaching 2.1 million annual passengers systemwide in 2025, which represents 87% of 2019 pre-pandemic levels and 23% growth from 2023 lows. METRO's on-time performance averaged 84.3% in Q1 2026, with the Congress Street corridor achieving 91% on-time rates due to dedicated bus lane pilot programs.
The average wait time for riders on METRO's frequent service routes (Routes 1, 2, 4) is 17 minutes during weekday middays, compared to 38 minutes on lower-frequency suburban routes, with weekend wait times averaging 28 minutes across the network. Customer satisfaction scores reached 4.2 out of 5.0 in the 2025 regional transit survey, with highest ratings for bus cleanliness (4.5/5.0) and driver courtesy (4.6/5.0).
"Portland has an enviable public transit system for a city of our size, especially considering we don't have the tax base of larger metropolitan areas. Our ridership recovery demonstrates that when you provide reliable, frequent service, people will choose transit over driving," said METRO General Director Sarah Mitchell in a March 2026 press statement.
Future Expansion and Investment Pipeline
Cumberland County transit agencies are seeking innovative funding mechanisms to sustain operations while addressing fleet replacement needs, new signage, and technology upgrades including Computer-Aided Dispatch and real-time passenger information systems requiring additional investment. The Maine Public Transit Advisory Council identified $47 million in immediate infrastructure needs for the Portland region through 2030, including 12 new buses ($4.8 million), 850 new bus stops with shelters ($12.7 million), and full GPS/real-time tracking implementation ($3.2 million).
Workforce shortages remain the biggest operational challenge, with METRO currently operating 3 positions below ideal staffing levels for drivers, causing some weekend route reductions and limiting frequency upgrades planned under Transit Together. The agency launched a $5,000 signing bonus program and increased starting wages to $22.50/hour in 2025, resulting in 47 new driver hires but still facing a 12-month training pipeline for certification.
Electric bus adoption is accelerating with three battery-electric buses delivered in December 2025 as part of a federal FTA Low-No grant, with plans to purchase 8 additional electric buses by 2028 to replace the oldest diesel fleet members. The depot charging infrastructure installation began in January 2026 at the Westbrook maintenance facility, enabling overnight charging for up to 15 electric vehicles by 2027.
