The last saturday, they opened a new metro station in "suburb". I wrote suburb inside quotation marks because Montrouge has 60,000 inhabitants per sq mi, so in reality this is more a dense inner city district that happen to not be inside the absurdly small city limits of Paris than a real suburb.
Paris city proper is only 40 sq mile ! Smaller than the small city limits DC, San Francisco or Boston, even the the Bronx is larger.
I love this new station, not only the station is beautiful but it shortens my commute of more than 30 minutes everyday !!
This is just one new station but I don't have to be stuck in the bus in traffic jam anymore.
This station was planned as far as the 20's, Montrouge has only waited 90 years to have its subway station.
The modern planning and the construction of this new 1.6 km or 1 mile of line just took almost 20 years.
When I see that in Spain (before the crisis) they could plan and build an entire line in just 5 years, I want to cry.
