So I first spotted this a few days ago, but I finally got a good picture this morning.
It seems there are two methods to embed track being used; the one we've seen the most of is for areas where there will be frequent need for level ground, so the concrete is at a single level and a gap is reserved inside each rail for the wheel flange.
The second method is for long stretches where there is no crossing happening, like Charles between Benton and Eby. In this method, the flange gap is omitted and the concrete set at a slightly lower grade.
This picture illustrates both, by showing a transition point.

There's still a piece of plastic as a spacer in the flange gap, for the record.
