Calgary, Transportation: Calgary Transit provides public transportation services throughout the city with buses and light rail. Calgary's light rail system, known as the C-Train, was one of the first such systems in North America (behind Edmonton LRT and San Diego Trolley). It consists of four lines (two routes) on 58.2 km (36.2 mi) of track. The Calgary LRT is one of the continents busiest carrying 270,000 passengers per weekday and approximately half of Calgary downtown workers take the transit to work. The C-Train is also North America's first and only LRT to run on 100% renewable energy.
As an alternative to the over 260 km (160 mi) of shared bikeways on streets, the city has a network of multi-use (bicycle, walking, rollerblading, etc.) paths spanning over 635 km (395 mi). The Peace Bridge provides pedestrians and cyclists, access to the downtown core from the north side of the Bow river. The bridge ranked among the top 10 architectural projects in 2012 and among the top 10 public spaces of 2012.
In the 1960s, Calgary started to develop a series of pedestrian bridges, connecting many downtown buildings.
