Fiveo, here is another one that will blow your mind.   In December 2016, rail service began through Switzerland’s newly completed Gotthard Tunnel linking Switzerland and Italy, which is the world’s longest and most expensive tunneling project.  The tunnel is 57 kilometers (35.4 miles) bored through solid rock at a cost of 11 billion Euros ($12 billion) and took 17 years to complete.  That averaged 2 miles of construction per year and $338.9 million per mile.   Compare that to HART which thus far has averaged 1.5 miles of construction per year to pour a little concrete at a cost of $500 million per mile.  What possible explanations can there be for HART construction being so slow and millions of dollars more per mile than other major rail projects?   Could it be politics?
