In this week's Throwback Thursday, architectural photographer Hunter Kerhart shows eight months of progress on 801 S. Olive Street, the latest Downtown development from Carmel Partners.

The first image, taken in February, captures the tower just past the halfway point of its 33-story climb.

The second, snapped earlier this week, shows that vertical construction and exterior glass work are nearly complete.

When finished in 2017, 801 Olive Street will feature 363 residential units and 10,000 square feet of ground-floor retail space.

The tower was designed by Chicago-based architecture firm Solomon Cordwell Buenz.
