Plus 15

About

The Plus 15 or +15 is a skyway network in Calgary, Alberta, Canada. It is the world's most extensive pedestrian skywalk system, with a total length of 16 kilometres (10 miles) and 86 bridges connecting 130 buildings, as of 2022. Calgary often has severe winters and the walkways allow people to get around the city's downtown more quickly and comfortably. The busiest parts of the network saw over 20,000 pedestrians per day in a 2018 count. The system is so named because the skywalks are approximately 15 feet (4.6 m) above street level. Some Plus 15 skywalks are multi-level, with higher levels being referred to as Plus 30s and Plus 45s.
