The PATH

According to Guinness World Records, PATH is the largest underground shopping complex in the world with 371,600 m² of retail space. PATH is a 27-kilometre (17 mi) network of pedestrian tunnels beneath the office towers of downtown Toronto, Ontario, Canada.

Here's what's connected in the PATH :

• More than 50 buildings or office towers
• Twenty parking garages,
• Five subway stations,
• Two major department stores,
• Two major shopping centres,
• Six major hotels,
• A railway terminal

The CN Tower and Rogers Centre are connected via an enclosed elevated walkway, called Skywalk, from Union Station. Once a year, businesses in PATH host the world's largest underground sidewalk sale.

There are more than 125 grade level access points and 60 decision points where a pedestrian has to decide between turning left or right, or continuing straight on.

Each letter in PATH is a different colour, each representing a direction. The P is red and represents south. The orange A directs pedestrians to the west, while the blue T directs them to the north. The H is yellow and points to the east.

Just a Toronto tidbit.
