Glacier Run construction hit a big milestone this week. Make that an 8,000 pound milestone.
An 8,000 pound acrylic window 5-inches thick, 13-feet wide and 21-feet tall (that’s as tall as a two-story building, wider than two full-sized pickup trucks parked side-by-side and as heavy as 15 grand pianos) was installed at the Zoo’s Glacier Run exhibit.
The window, designed to contain 85,000 gallons of water in the polar bear outdoor pool and withstand a full grown 1,000 pound polar bear swimming at full speed, was lifted with a 65-ton crane.
It was one of four large acrylic windows installed this week—one for seal and sea lion viewing and three for polar bear viewing (including the 8,000 pound one).
Local media showed up to cover the installation and talked to Mark Zoeller, Louisville Zoo Assistant Director, and Tom Young, Project Manager with Whittenberg Construction.
