"We are responsible for implementing mobility solutions that preserve and enhance quality of life in Central Texas as we EVOLVE with the changing regional landscape, ENGAGE with the communities we serve, and PROTECT the environment we all share."

The Mobility Authority is committed to balancing the need for new infrastructure with the preservation of the environment. Specifically, this means expanding people’s views on transportation to understand and embrace the role that our environment plays in achieving mobility solutions and overall regional health. And delivering on that commitment means incorporating sustainable design principles into the development and construction of our projects.

The month’s Expressway News features the final segment of our three-part series outlining the ways in which the Mobility Authority upholds it’s mission to evolve, engage, and protect.

As an agency charged with enhancing quality of life, we’re committed to developing innovative transportation solutions that protect our region’s natural resources. We do this by mindfully incorporating environmental stewardship from the conception of Mobility Authority projects through construction and beyond. And through these efforts, we’re able to minimize our environmental footprint while reinvesting in our community. 

The 45SW Toll Road, for example, is an industry-leading model for environmentally responsible roadway construction. From conception through design and construction of the roadway, the Mobility Authority used Best Management Practices (BMPs) meant to protect the sensitive Edwards Aquifer Recharge Zone and ensure water quality protection. Part of the project design included the development of a Water Pollution Abatement Plan (WPAP) which details both temporary and permanent stormwater runoff control measures.

In 2018, the Mobility Authority was awarded the Austin Chamber of Commerce’s Environmental Champion Award for its investment in sustainability, innovation, and leadership in the transportation industry, most notably due to the SH 45SW Project.
Once again, the Mobility Authority practices this value by seeking opportunities outside of projects to protect and reinvest in our community’s environmental health. Most recently, we partnered with TreeFolks to preserve and expand the urban tree canopy here in Central Texas and along our project corridors. It is through this partnership that we’ve provided more than a dozen educational classes and tree planting events, online video workshops, installation of two irrigation systems at local elementary schools, and have planted an estimated 10,000 trees throughout Central Texas.


Mobility Authority to Hold Virtual Open House  

The Mobility Authority and TxDOT have resumed efforts on the MoPac South Environmental Study. We invite you to engage in the process as we continue working to identify a solution that improves safety and mobility for drivers, transit riders, bicyclists and pedestrians in a manner that promotes environmental stewardship and sustainability. 

Mark your calendar for the
MoPac South Environmental Study Virtual Open House

Please join us on Zoom 
Thursday, November 4th | 6:30 p.m.

We want to meet you (virtually) to update you in detail on the 183 North Mobility Project, answer any questions you have and share how the upcoming improvements will benefit the residents, commuters and businesses along the US 183 corridor in northwest Austin.  

The Great Hills Constructors construction team will be able to give you more detail on the overall construction schedule, further explain the improvements to come and illustrate the latest technologies that will be used on the roadway.

About the 183 North Mobility Project
The 183 North Mobility Project aims to improve mobility, reduce congestion and provide more reliable travel times for transit and emergency responders along the 9-mile section of US 183 between SH 45 North and Loop 1 (MoPac), a critical corridor in our regional transportation network.

The project includes the construction of two express lanes in each direction and the addition of a general-purpose lane to bring the number of non-tolled lanes to four in each direction. The project will construct an express lane direct connector between the new US 183 express lanes and the existing MoPac express lanes. The project also includes operational improvements to southbound MoPac, new shared use path connections, new sidewalks and cross-street connections for bicycles/pedestrians.

When completed, those looking to bypass traffic congestion will have a choice to use the 183 North Express Lanes. Drivers who prefer not to pay a toll will still have the option to use the improved non-tolled general-purpose lanes.

Construction is set to begin early 2022.


The holiday season is upon us – and with it comes traffic. As more people hit the road, it is important to take necessary precautions during the hectic holiday season. Whether you’re driving across the country or across town, follow these tips to keep spirits high and everybody safe.

1. Perform a maintenance check on your vehicle. Checking your vehicle becomes increasingly important with the increase in cold weather and rain. Before you hit the road, perform a check of your vehicle’s engine, fluids, headlights, windshield wipers, brakes, turn signal, and tires.
2. Be flexible in your travel plans. If you can, try to avoid leaving during peak traffic hours. Leave a bit earlier than you originally planned in order to beat some of the rush.
3. Be patient. It is important that you not let frustration affect your driving. Avoid the temptation to speed, tailgate, or make unsafe lane changes or passes in an effort to get ahead of traffic. These are very dangerous as other drivers can't predict those actions.
4. Designate a driver. If your get-together will involve alcohol, be sure to designate a sober driver. Drunk driving crashes tend to spike during the holidays – don’t allow yourself or your family members to become part of the statistics.
