It would probably only be to Naperville by now. Here are some interesting comparisons:

10 miles of the original Transcontinental Railroad were built in ONE DAY
1 mile of the Lakefront Path here in Chicago has taken 6 MONTHS

I’m still researching figures, but I’d guess 1 mile of the Transcontinental Railroad cost less to build than 1 mile of the Lakefront Path in inflation adjusted figures.

I’m very excited to have the path improvements, but the time and expense it took seems a little extreme. Maybe the city should do a little research at the Stanford Library to learn tips about project management from 1867…
