Just when we thought taking public transportation couldn’t get any more tedious, the schedules decide to change on us.

There is a silver lining here, though, as some routes are also being added to help Calgarians get from A to B as quickly as possible.

The city revises the bus routes four times a year, making small adjustments here and the occasional big change there.

Many of the extensions being introduced this December 23 come due to the creation of the MAX Yellow line — the fourth addition to the MAX rapid bus system that was first implemented late last year.

Keep yourself informed on the comings and goings of bus schedules to ensure that you’re not – literally – left out in the cold.
