It is actually a MdTA project. There are meant to be two phases, but so far only the first phase (KH-1301-000-006) has been advertised. The second phase (KH-1302-000-006) was supposed to be advertised two years ago this coming autumn, and I have actually seen draft signing plans for it, so I think MdTA has final PS&E sitting on a shelf while it waits for funding to come through. Phase 1 is enough to build a complete Maltese cross stack interchange, but Phase 2 is needed for the managed lanes and additional flyovers to complete what MdTA bills as a "six-level" stack.
In the case of the I-95 rehabilitation south of the Fort McHenry Tunnel (FT-749-000-006), MdTA advertised the contract for the second time last January on a much smaller plans set than was used for the first advertisement, indicating that the project had been rescoped to allow it to be built within the limited funding available. I don't think the I-95 rehabilitation is unique in this respect, and the cut in project scope points to serious cashflow problems.
