They already have a Regional Tax District setup to give money to the Metro. I assume they will raise that Tax during the next session saying that they are going to use the money to fix I-95 and I-66 then spend that money somewhere else. Because that is what they do.
DC Metro has stated they need $500M in annual revenue form regions to operate....and that the revenue stream must be “bondable”
In other words, they will borrow all the money they can today based on a future revenue stream from service which may or may not be provided in a quality manner or at a reasonable price.
What they aren’t admitting is the pension funding problem that they have. I suspect that’s where most of the money is going to go.
