2019 13km Nansha (南沙大桥) Bridge over Pearl River in Guangdong Province

(Satellite) (Chinese:南沙大桥)  The previous name was Humen Second Bridge.

The crossing consists of two suspension briges and helical ramps to provide access to the Hai'ou Island.

"On April 2nd, 2019, the [13km] Nansha Bridge, formerly known as the Humen Second Bridge, was officially opened."
"The Nansha Bridge comprises two cross-river mega-span suspension bridges. For the first time globally, the project involves two cross-river suspension bridges with their respective main spans exceeding 1,000 meters [3/4 mile]. The Dasha Waterway Bridge is a twin-tower single-span suspension bridge with a main span of 1,200 meters. The Nizhou Waterway Bridge is a twin-tower double-span suspension bridge with a main span of 1,688 meters [1 mile], making it the largest steel box girder suspension bridge in China."

I do not understand what they mean by "double-span" above. I can find only one span for the longer bridge. I noticed that the waterway is indeed busy.

Construction started in 2014.

The bridge not only has the world's longest steel box girder span (1,688m or 1 mile), it's the widest steel box girder suspension bridge at 40.5m (133').

The entrance and exit for the island use helical roads to change between street and bridge level. I see very few cars on those 2-lane ramps. Although America would also have two lanes, but one of them would be a shoulder.

Treon Jooce Jackson: This can't be China though. Cars go the opposite way on the road. They travel forward on the left not the right.

I looked closely at this photo to check the occupancy of the ramps. Then I realized that the photo above is a cropped version of this photo. I also found this photo on Twitter.

The helical ramps get a "Spaghetti" award.

The project set several records for continuous pours for both surface and volume jobs.
