Detours for vehicular traffic on Saturday, April 26, from 6 a.m. to 2 p.m.: Île Sainte-Hélène will be accessible via the Jacques-Cartier Bridge, while Casino guests will have to use the Concorde Bridge.

Transit between the two bridges will not be possible during this period.

Rue des Seagull is one-way between Macdonald Road and Parking lot P11 due to the establishment of a pedestrian detour that provides access to the Biosphere.

The work taking place at the Biosphere should be completed by early June 2025.

Delays and detours to be expected, reduce your speed and follow the directions of the traffic signs.
