Doesn't give final url and domain

[manojmali1991]

I need the final url location

e.g.
I want to scrape following url
A: http://bit.ly/1TcDGBI

this redirects to

B: https://medium.com/@jamnopeanut/facing-three-months-in-rikers-for-climbs-on-statue-while-protesting-police-murder-85dd5062523a#.l3qaty8r5

So I need this unshortened url B.
How can I get it?
