The 108 kilometers of the 407 ETR runs parallel to the 401 city ring road, one of the busiest highways in North America and the world.

An average of 380,000 trips are made on this road every day. Behind these are thousands of individual stories that require reliability, speed, and safety.

The 407 ETR also tells a story about large numbers and innovation. That story began in the 1950s, and it is still alive today. More than a million tons of asphalt materials were used to build it. Seven million cubic meters of embankment fillers were created.

The 407 was also the world’s first open-access electronic toll road. On it, cars never stop: they just drive, and technology takes care of the rest. Traffic is lower, times are improved, and safety is higher. Moreover, 108,000 tons of CO2 equivalent emissions are cut each year.

Crossing 232 bridges, the road turns on itself over and over again, creating whimsical shapes made of concrete, false symmetries between beams and columns. With two hundred ramps and 40 connections, the 407 ETR connects the Canadian region of Ontario around the capital. It’s always there. When the heat and humidity rise from the smallest of the five great lakes. And when everything turns to ice.
