Société de transport de Trois-Rivières (STTR) was formed in 2002 to operate transit services, after the merger of the six municipalities that today constitute the city of Trois-Rivières, Quebec, Canada. Previously the Corporation intermunicipale de transport des Forges (CITF) had provided service in the area since 1979. It covers a population of more than 126,000 people with its urban bus routes, school buses and tours, carrying more than 8200 users per day for a total of about 3 million trips a year.
