The 28-kilometer-long flyover, built in 2013, was designed for the Bus Rapid Transit (BRT) serving over 300,000 commuters every day. /Sichuan Daily Photo

The flyover is supported by 4,280 pillars, all carpeted with rich Boston Ivy which was chosen for its effect in creating oxygen and lowering temperatures. /Sichuan Daily Photo

The fresh greenery has added vitality to the concrete jungle and woken up sleepy commuters in hot summer days. /Sichuan Daily Photo
