The Gladys Porter Zoo is relieved to be entering the final phase of a major infrastructure project to update sewer and water lines that have been in use for over 50 years. This overhaul is a necessary precursor to the future construction of various upgrades that will enhance the zoo visitor experience, improve staff operations, and most importantly, ensure the best habitat conditions for our animals.

The exciting new exhibits and visitor amenities outlined in Phase II of the Zoo’s Master Plan include a new African savannah that will provide a spacious habitat for a pride of lions, as well as an adjacent visitor plaza leading into an air-conditioned nocturnal building. These features will create a dynamic new destination at the heart of the Zoo. Phase II also includes the construction of a completely reimagined Small World with sensory-friendly amenities designed for children of all abilities. Neither of these projects would be possible without the completion of the zoo’s present infrastructure project, which is nearing completion.

Construction crews have been hard at work behind the scenes since January 2025 and the project has now moved into public areas of the Zoo. Over the next four months, visitors will notice temporary pathway closures near the Small World area. These closures will gradually spread toward the Special Events Building and the Exit/Gift Shop complex.

Currently, staff are asking visitors to turn right upon entering the Zoo. Pathways on the right side will remain open and unaffected. The Zoo will share frequent updates so visitors can plan their trips with the latest information on path closures, alternate routes, and exhibit access.

While some exhibits may be temporarily inaccessible at times during construction, there’s still plenty to enjoy:

All animal feedings will continue uninterrupted on weekends (weather permitting)

The Herpetarium, Aquarium and Australia building will remain open throughout the entire project

The Zipline will continue operating for thrill‑seekers

“We appreciate the patience and understanding of our guests as we complete these important improvements to the Zoo,” said Zoo Director, Dr. Pat Burchfield. “Updating our failing sewer and water lines is a high priority due to their age and fragility. Completion of this project will allow us to then move forward with dynamic enhancements that will ensure the Gladys Porter Zoo continues to attract visitors to our area while remaining a source of pride within the South Texas community.

This project was made possible by a grant obtained by the City of Brownville for the purpose of ensuring long-term community growth and opportunity. The Zoo is extremely grateful for the City support provided throughout the Zoo’s master planning process and beyond.
