The New Britain–Hartford one is costing $63 million per mile, which is way more than a lot of equivalent rail projects.”
Name one...within the past decade.
Now just what do you mean by that question?
NJ Transit’s River Line (diesel light rail) is 34 miles long on one of the country’s oldest railroads (the Camden and Amboy), and it cost $32 million per mile, which is itself a lot of dough for rebuilding an existing railroad—but it is half the cost per unit length of this BRT corridor.
I don’t know if you’re trying to justify spending on BRT, but I suggest that we all avoid playing politicians’ games ourselves.
