The first tube of the Lincoln Tunnel (today the center tube) was opened on December 22, 1937, at a cost of $75 million.
Although inflation probably means that $75M may be close to a billion dollars today, you would think technology would have made some cost savings advances over the last 75 years. Unfortunately, it seems as if the opposite has occurred since nearly every proposal is multiple billions of dollars.
The ARC tunnel project was $9.8 billion (before cost overruns)
The subway extension to NJ was also estimated to cost $10 billion.
The GATEWAY project for AMTRAK is estimated to cost $13.5 billion
I realize that these projects are a more complex than just the center tube of the Lincoln Tunnel, but it still seems as if the price has risen more than just monetary inflation.
