The zoo recently posted about their next major exhibit project:
The African Experience. This $16 million project will include a new penguin exhibit with underwater viewing, and will also transform the existing Serengetti Crossing exhibit to add a waterhole, unobtrusive viewing barriers, and add additional hoofstock. The majority of the funding has already been secured, and the zoo is accepting donations on their website to get the remaining funds necessary.
