It is open today
You might be thinking of the nearby Parcel 7 garage. It reopened last Friday. It seems they fixed up the stairways and painted about half of the garage. Also, Government Center garage itself is open, the helix is gone and the main entrance is now at the end of Bowker street By BPD's Area A1 station The New Sudbury entrance has one lane in and out lane out now.
