Future Landscaping

Once construction is complete on the MoPac Intersections project, TxDOT will utilize the Green Ribbon Program to plant native species within the right of way along the project limits. We are excited about the program and have some initial concept ideas ready to share.

Learn more about the Green Ribbon Program and other Green Ribbon Program plantings in the Austin District.
