OC Transpo will be starting its summer service on Sunday, including a new round of route changes that might affect the number on the front of the bus you take to work.
As of Sunday, 15 bus routes will have new numbers, 43 routes will see changes to service, and a brand new route, 179, will be launched.
Among the route-number changes, say goodbye to the 1, which will become the 6. The Confederation Line will be known as Line 1 when it opens.http://www.metronews.ca/news/ottawa/2017/06/19/get-ready-summer-oc-transpo-changes-may-affect-your-commute.html
