The G76 expressway has so many large and high beam bridges that the extradosed Longjinghe Bridge is a breath of fresh air, curving across a remote river valley in the mountains north of Nayong city.

The central span consists of double cable planes that arc across an 850 meter radius using a 4 ° lateral slope. The spans are 86 +160 +86 meters. The main deck is a 28 meter wide single three-compartment box with a depth of 6.5 meters at the towers and 3 meters at mid-span. The double-walled rectangular piers are 60 meters tall. The two main towers rise 28 meters above the road deck and support six pairs of parallel stays that are spaced 4 meters apart at the deck.

Just a kilometer to the west is the newer Naqing expressway cantilevered beam bridge.
