To find out more about the work planned for this summer on the different bridges in the region, check the Work onpage Interprovincial Bridges – Spring and Summer 2019.
Despite these measures, some delays are to be expected
Consequently, the STO asks riders to be patient and thanks them for their understanding. The most challenging periods in the system are from 7 to 8:30 a.m. and from 4 to 5 p.m. Residents who have a more flexible schedule and can change their usual travel patterns are encouraged to do so.
Every day, the STO makes changes to its routes depending on the developing situation. Transit riders are strongly advised to check the Web site regularly to get service updates via the System-Info alerts.
