One question I've always had about the extension of the BSL to the Navy Yard...and I admitted know nothing about such infrastructure/rail construction.
Couldn't you just cut a hole into the ground, elevate the tracks, and have the BSL go above ground, simply run along the road (Broad Street) to the Navy Yard and then down the main street there? Or has that always been the plan? I just don't understand why it costs $1-2 billion to cut a hole, elevate to ground/street level, and install some wires - electric. (if this is a really dumb idea, my apologies!).

Not a dumb question at all. Infrastructure costs more in America than almost anywhere else, and many transit planners, engineers, etc have made a focus to try and understand exactly why that is (Alon Levy is one name I know who's done research on the subject). Between the incredibly complex (and arguably unnecessary) regulatory steps required (such as Environmental Impact Statements) to how we bid contracts, staff projects, etc, it all adds up to sums that are basically insurmountable anywhere where there's a shortage of funds (which is everywhere). Another factor is that we seem to "over-engineer" projects, making them deeper, wider, taller, etc than they really need to be, ballooning costs. Overarching point being, an overground or underground extension of less than a mile should not cost $1 billion, but because it does, the only way to pay for it is federal dollars.
Which brings us to the other side of the issue: lack of political will and entrenched anti-transit bias in prioritizing spending for such projects. There is always money for the things deemed necessary (rebuilding I-95, for example). The federal government could take steps to simplify regulatory processes and expand dollars available for these kinds of investments, but they generally do not.
