they were pouring the platform for the reconfigured Muni stop in front of Chase Center yesterday
northern end waiting to be poured
looking at the southern end again, that seems to be a ramp down, which would imply a mid-block crossing.
edit: and just noticed what are probably the corresponding traffic signal poles
Third St from ground level
and from farther south
work on the T-Third Loop does appear to be underway again. this is Illinois
and more evidence that another of the area's long-stalled projects is also underway
