Terms & Conditions of use
- By using Google Trip Planner you agree you have read and accepted the following:
- Mountain Line strives to provide the best information possible for Google Transit, but cannot guarantee absolute accuracy. Mountain Line recommends riders double check their trip itinerary by viewing the published bus maps and schedules here, or by calling the Mountain Line office at (406) 721-3333. In addition, please read the Google Transit Terms and Conditions.
- I received incorrect information:
- If your Google Trip itinerary has inaccurate stop locations, times, fares, or service information, it’s likely due to dated information that needs to be updated between Mountain Line and Google Transit. Please record the origin, destination and arrival/departure date and time for your itinerary and send an email with this information to firstname.lastname@example.org. Through your feedback, we can make this service even better for everyone!
- Other considerations:
- Some routes may be drawn as straight lines from stop to stop, and do not follow the actual route of the bus on the roads.
- The trip planner will provide two or three suggested trip plans. We recommend you always check these alternative trip plans as they may provide a trip that better meets your needs.
- Walking directions and times may be inaccurate, sometimes suggesting walking across unpassable obstacles. Google is working to improve walking directions.
Using a Route Map
You can find route maps and schedules here. To use these tools to plan your trip, follow these instructions.
- Find the route and time point closest to your departure point.
- Find the route and time point nearest your destination.
- Determine if you need to transfer routes. If you need to transfer and the arrival of your bus/ departure of the bus you are wanting to transfer to overlap, request a transfer from your current driver to ensure you don’t miss the connection.
- Determine which direction you need to go. Schedules are broken into trips heading Outbound from Downtown and Inbound to Downtown.
- Be sure to leave enough time to arrive at your stop a few minutes early.
