Located midway between the super cities of Xian and Chengdu, the spectacular Longdongbei arch bridge carries a 2-lane road high above a deep crevasse with a span of 120 meters with a 6:1 rib rise ratio. A modern 4-lane highway arch bridge with a span of 145 meters was built 100 meters downstream of the older arch span and opened in 2011. The new arch span is 90 meters high or approximately 40 meters lower then the older arch. The bridges are located about 25 kilometers northeast of Guangyuan City.
In 2016 a vehicle caught fire on the G5 Expressway bridge.
The new highway arch is located just 100 meters downstream of the older arch.
