Laval is a Canadian city in southwestern Quebec, north of Montreal. It is the largest suburb of Montreal, the third largest city in the province after Montreal and Quebec, and the thirteenth largest city in Canada with a population of approximately 500,000. Laval is a modern city in full expansion. With one of the highest population growth rates in Quebec, it stands out for its exceptional infrastructure, economy and quality of life. Five highways and four highways crisscross Île Jésus. In some places, the traffic flow is really impressive. This is the case at the interchange on Highways 15 and 440, where the average annual traffic flow is 300,000 vehicles, the same as at the Turcot interchange in Montréal*. Laval also has an intermodal public transport network that includes three subway stations. As for buses and collective taxis, they transport 20 million passengers per year. The 235 buses of the Société de transport de Laval (STL) provide efficient public transport throughout the country. The STL network makes it possible to offer users optimal intermodal services including buses, three metro stations and the stations of the two suburban train lines. Since 2011, Laval has had a new road link to Montreal: the 1.2-kilometer toll bridge on Highway 25, which is the longest guyed structure in Quebec.
