The National Museum of African American History and Culture in Washington D.C. has been under construction since 2013. There has been some fantastic momentum on the structure recently.

In this gallery, we'll take a look at how the structure was looking as of the end of 2014, plus, most recent construction.

And, take a look at how the construction was going a few months ago in our previous photo gallery.
