Important road closures: update, September 17 to 25

Due to road closures related to the UCI Road World Championships taking place throughout September, please make sure to plan for changes to your usual commute, particularly if you have a medical appointment.

Routes vary each day depending on the events, which means that affected areas and street closure times will be different from one day to the next.

Plan ahead before leaving and allow extra travel time, whether you are driving or taking public transit.

Between September 19 and 25, please use Sherbrooke Street and University Street to access The Neuro, and Sherbrooke Street and Côte-des-Neiges Road to access the Montreal General Hospital.

Consult the map of daily road closures here.

We encourage you to use public transit. Some bus routes will be detoured. You can visit the STM website for more information. On September 21 and 22, staff travelling to Montréal from the South Shore can use the free park-and-ride facility at the Chevrier parking lot in Brossard. Free shuttles will provide service to the Du Quartier REM station between 6 a.m. and 10 a.m., and between 3:30 p.m. and 7 p.m. Parking and shuttle service are free; however, a valid transit fare is required to use the REM.
