Regional Transportation Program (RTP) Half Fare Card
Casco Bay Island Transit District, the Portland METRO, and the South Portland Bus System all accept the Regional Transportation Program Half Fare Card as well as Medicare cards to validate half fares for persons with transportation disabilities. We ask your assistance by always presenting proper ID when purchasing half fare tickets.
If you do not have a Medicare card but think you qualify for half fare tickets, please visit the offices of the Regional Transportation Program (RTP). Bring proof of your condition (e.g. a doctor's note) so they can issue you a card. We do suggest that you call ahead (774-2666) to make sure you have all the information they will need.
The RTP offices are located in the METRO bus headquarters at 127 St. John Street (entrance on Valley Street).
Directions from Casco Bay Lines:
Turn left onto Commercial Street. Proceed to the light at Route 1 (Veterans Memorial Bridge). Turn right onto Valley Street. The METRO and RTP offices will be on your left after the light.
Frequent Rider Pass
The Frequent Rider Pass program is designed for convenience while offering savings to those who travel with Casco Bay Lines more than 5 times per week.
How to Get Started: Purchase a pass for your island destination at the ticket window for $5.00. You will need to have your picture taken, so please plan to come at a slow time (not just before boat departure!). A laminated photo ID card will be made for you and will be available in a day or two.
There are two types of passes: Annual and Monthly pass.Annual Pass
This is the easiest option and the most cost-effective. The Annual Pass is pre-paid for one full year from the date of purchase and allows you unlimited passage to the island. The Annual Pass also includes transportation of one bicycle along with the passholder.
