"Nowhere near done" seems like a bit of an exaggeration, given that the link at the top of your linked page suggests that it's over 3/4ths done[1].
It's also, to my understanding, not grade-separated in various important places. I was in College Park two weeks ago and saw lots of at-grade development on the line, which presumably gets bogged down by Route 1 and the other high-traffic roads nearby.
(This isn't to imply that the construction isn't slow or inefficient; it's almost certainly both of those things.)
