So, perhaps 2020s China ~ 1950s US demographics. The bridges that recently collapsed in the US (2024 Baltimore/Francis Scott Key Bridge and 2007 Minneapolis I-35W Mississippi River Bridge) were built in 1964 and 1972-1977 respectively.
Noone has yet compared the Chinese construction times/costs to the replacement Baltimore Francis Scott Key Bridge: cost ~$2b, estimated October 2028. Will have 600ft bridge towers, 1600ft main span (increased from 1209ft), total span length 3300 ft, improved pier protection. Surprised they didn't add a freight rail link.
