If you’re looking for the permits, 164 North Peoria is the address you’ll want. If you’re looking for details on the soaring new West Loop apartment Tower, 900 Randolph is the name you need.

Okay, it might not quite be soaring yet. But at 43 stories, 900 Randolph will soon be the tallest building in Chicago west of Halsted Street (not the Kennedy; I think that designation stays with 727 West Madison), as the West Loop and Fulton Market neighborhoods continue to grow upwards and outwards. And it’s making its way up, as the core appears to have reached the 14th or 15th floor.

Let’s catch you up on the latest progress, photographed Sunday, May 1.
