(Satellite, construction started in late 2019, and the bridge has yet to show up on Google Maps.)

The total cost is US $3b. [instagram video]   

I don't care for the host-based format for a video, but there is enough scenes and info to make it worth watching him being dramatic on a tower. He keeps mentioning that there were a lot of innovations, but he never gives even one example.

"The world's largest horizontal arm self-elevating tower crane started operation at the construction of the Changtai Yangtze River Bridge, the world's longest-span railway-highway cable-stayed bridge, on Feb 28."
[At first, I thought the Yangtze delta had a lot of fog. But now I think I'm seeing smog in most of these photos.]

This is a better view of the heavy lift barge crane.

"The tower crane is capable of hoisting steel components as heavy as 300 metric tons or more to the height of 370 meters. As a mini building hoist is installed inside the machine, it's easy for workers to move up and down during construction."

"The Changtai Yangtze River Bridge connects Changzhou City and Taizhou City, with a main span of 1,208 meters. It is the world's largest cable-stayed bridge for both highway and railway use."

I do not understand why I can't find any evidence of the bridge in this Nov 2023 image.
