Consider that the Holland Tunnel opened in 1927, connecting New Jersey and Manhattan. It cost about $48 million to construct, equivalent to about $890 million today.
Consider that the Hudson Tunnel Project, an ongoing effort to build and revitalize rail tunnels to New York City, is currently estimated to cost more than $16 billion.
Why has infrastructure gotten so much more expensive to construct in places like the US?
There are a variety of ways to answer this question. Labor has gotten more expensive. Regulations have proliferated. Raw materials are harder to source. And so on.
