Click on the shuttle symbols along the route to view upcoming shuttle times for a particular stop. The 'departure' times in the pop up balloons are estimates of the shuttle's arrival time to that stop based on its current location. This time will update if the shuttle is running early or late. If the shuttle is early it will still depart at its regularly scheduled time.
Some shuttle stops on the map share the same bus symbol due to their close proximity to each other. In these instances, click on the stop name in the list above to get times for each stop.
