It appears that the work being done at 1st and M (wrapping back toward L Street) is plumbing/pipe work of some sort under the street and sidewalks, not any-second-now demolition of On Luck and the other buildings (although I imagine that's not far behind, given that construction on 100 M Street
is supposed to start "late summer 2006" according to Opus East
). And the Sunoco station at 50 M Street is indeed now being dismantled. But still no announcement of any big deal for that lot.
