Ride the #80 bus past 4445 West Irving Park Road and you won’t see many new signs of construction on Northwestern Medicine’s 4-story facility. But get off the bus and take a peek into the abyss and you’ll see there’s a lot going on below street level. The block-long site still looks like a deep excavation, but not nearly as deep as the first visit back in April.

Compare those April photos to the gallery below, and you’ll see how far the tag-team of Power Construction and UJAMAA Construction has come on the CannonDesign facility.

Enjoying the photos? Metra and CTA rides (and Amtrak trains to Milwaukee), Zipcars, Divvy Bikes, camera lenses, domain fees, snacks & energy drinks, and comfortable walking shoes add up. You can help offset expenses by making a greatly-appreciated donation to Building Up Chicago.
