Living Connections - Illumination of the Jacques Cartier Bridge
All the nights - Jacques Cartier Bridge
Jacques Cartier and Champlain bridges incorporated
The Jacques Cartier Bridge lights up and comes to life every night !

With the completion of the luminous interactive work Living Connections, the Jacques Cartier Bridge becomes the world’s first networked bridge. It lights up and comes to life every night thanks to intelligent programming that adapts to the seasons and the city’s energy. Activated by millions of human and natural connections, the bridge awakens at sunset and goes to sleep with the day’s first light. The city’s ambitious, innovative new luminous signature is a tribute to an iconic architectural feature of Montreal’s urban landscape.

As the seasons change, so do the lights
The bridge changes with the seasons thanks to a 365-colour calendar. Day after day, the bridge core gradually shifts from an energizing spring green to a radiant summer orange, a voluptuous fall red, and finally an icy winter blue. Thanks to the way its colours change gently with the seasons, the light subtly evokes the passage of time. ?

A reflection of Montreal’s energy
The bridge captures the pulse of Montreal life in real time. The intensity, speed and density of the light changes depending on how often Montreal is mentioned on Twitter. As the bridge pulses with the city’s social conversations, it reflects Montreal’s energy. ?

Every new tweet sent with the hashtag #IlluminationMtl is sent to the bridge’s illumination system. The tweet is then transformed into a moving light in the colour of the day. If the tweet is favourited, the moving light expands. If it is retweeted, it accelerates. Otherwise, the moving light disappears after a few moments.

Like clockwork
As the day’s first light appears on the horizon, the bridge comes to life in a dance of lights, gradually revealing that day’s colour.
Every hour at night, short 5-minute animations visually translate Montreal’s mood based on different types of daily data: the weather, traffic, news, major events, and more. The bridge is then taken over by luminous movement, coloured according to the hottest topic of the day in Montreal media: SOCIETY (red), ENVIRONMENT (green), TECHNOLOGY (light blue), BUSINESS (grey), SPORTS (blue), INSTITUTIONS (pink), CULTURE (purple).

At midnight, the bridge is activated, like an urban clock. It cycles through all 365 colours on its calendar, looking for the colour of the day. It continues to illuminate Montréal’s nights until it goes back to sleep at 3 a.m. (1 a.m. in winter). Only the high turrets and supporting piers remain softly lit until daybreak.

And then, with the first rays of dawn, it stirs from its slumber to bid good morning to early risers. It is lit up, subtly, with lights mimicking the colour of the sky in real time.

This evolving, networked, interactive content transforms the bridge into a barometer of Montreal life and of Montrealers’ energy and liveliness. A world first!

Living Connections is produced as part of Canada’s 150th anniversary and Montreal’s 375th anniversary, with the financial participation of the government of Canada, the government of Quebec, the Ville de Montréal and the Great Montrealers.
