About | PJCCI


The Jacques Cartier Bridge Living Connections is a unique interactive lighting concept that, for years to come, will be activated in real time by the seasons and the energy of the city. 

This ambitious, innovative luminous signature is a tribute to an iconic feature of Montreal’s urban landscape.

Thanks to intelligent programming, this first connected bridge comes alive every night. An iconic landmark during the day, the bridge comes to life at sunset, marks the new day at the stroke of midnight, and goes into sleep mode at daybreak. Activated by millions of data that make up the pulse of the city, the bridge becomes a unifying, living and lasting symbol.

As the seasons change, so do the lights
As the seasons change, so do the lights

The bridge changes with the seasons thanks to a 365-colour calendar. Day after day, it gradually changes from an energizing spring green to a radiant summer orange, a voluptuous fall red, and finally an icy winter blue. The light subtly evokes the passage of time.

Every hour on the hour, short animations visually translate Montreal’s mood. These animations are customized to the moment by traffic, weather and social media data collected during the day. 

Dominant themes in the media translate a specific colour to the bridge: environment is green, technology is aqua, business is yellow, sports is blue, institutions (religious, political & justice) is pink, civil society (health, education, lifestyle & leisure) is red and arts is purple.

The pulse of Montréal

The vitality of Montrealers is constantly seen through a subtle flickering of the lights. The intensity, speed and density of the light particles varies with mentions of Montreal on social media.

''Half-masting'' for the illumination
''Half-masting'' for the illumination

Being a federal Crown corporation, JCCBI ensures that the illumination of the Jacques Cartier Bridge follows the notices of half-masting of the Canadian flag, issued by Canadian Heritage. “Half-masting” for the illumination also occurs when the Government of Quebec announces the holding of state funeral or national funeral.

The annual illumination programming is then interrupted exceptionally, and the illumination is dimmed or “half-mast”. 

On August 2, 2021, JCCBI modified the procedure for “half-masting” the illumination of the Jacques Cartier Bridge.
