Just always wondered why the 6 line is underground in the bronx up till just outside hunts point ave?
All the other IRT Lines Come above ground pretty much in the lower bronx... but the 6 travels quite a way before
becomes elevated...
And How Come The B/D Concourse line wasnt elevated? Especially with the concourse being as wide as it is.. Are
these a topography issue? (high water table,etc) with both lines?
It seems that its been always cheaper to build above ground then below for the obvious reasons...
I rode the 6 earlier this afternoon to see a co worker to Elder and I was just thinkin to maself...this line is still
underground after like 5 stops in the bronx......lol...Just lookin for a lil insight as to the construction method for
these particular lines...Appreciate yall!
