The Miami Metrorail 2.4 mile extension to the Miami airport opened this week. I was wondering when was the last actual track mileage extension with a new station of a rapid transit heavy rail system in the US? Not an infill station or a rebuild, but an actual extension of a Metro rail system?

The last extension to the DC Metro system was the Blue line 3.2 miles extension to Largo Town Center in December, 2004. When the last extension to BART? Any other Metro or subway system extensions since 2004?

In the next 4+ years, the 11 miles and 5 stations of the DC Metro Silver Line phase 1 will open (December 2013 projection), #7 Line extension in NYC in 2014?, then the Second Ave Subway phase 1, so the new few years will be busier than the last few.
