Raising the bar on what it means to be “Green”

The Mobility Authority is committed to environmental stewardship by balancing the need for infrastructure improvements with preservation of the natural resources that make us proud to call Central Texas home. Delivering on that commitment, we have incorporated sustainable design principles into the development and construction of the 183 South project. We are also a longtime sponsor of TreeFolks, a Central Texas non-profit that seeks to strengthen communities through planting and caring for trees. These initiatives allow us to minimize our environmental footprint on the Central Texas region while reinvesting in our community.

Expanding the East Austin Tree Canopy

In 2017, we partnered with TreeFolks and a major employer along the 183 South corridor—NXP, to sponsor the installation of an irrigation system at Norman Elementary School, located near the project corridor. We held a community tree planting event where students, project team members and NXP employees planted shade and fruit trees and spread mulch.

Next year, we anticipate working with additional partners to continue bringing the TreeFolks mission to life.

Sustainability by Design

The sustainable measures being incorporated into the project will result in less construction noise, less intrusive glare and disruptive light pollution, reduced emissions, greater aesthetics, and assurance that the project design is reflective of community values. The 183 South project includes major investments in east Austin such as the restoration of the nationally-recognized historic Montopolis Bridge, which will be decommissioned from vehicular use and preserved for bicycle and pedestrian recreation and travel.

We are working to raise the bar industry-wide for what it means to design, build, and operate a sustainable roadway. The 183 South Project will be considered for certification by the most widely-used transportation sustainability rating system worldwide — Greenroads®. This third- party system evaluates design and construction against a set of criteria, and assigns a rating to truly gauge environmental responsibility.

A Greenroads® rating will be assessed following project completion in 2020. For more information on Greenroads®, click here.
