Central Texas Regional Mobility Authority Projects Projects & Programs The Mobility Authority is working to create a comprehensive regional transportation network for Central Texas by implementing innovative and multimodal transportation solutions. Our system of roadway projects is designed to bring you faster, safer and more reliable drive times throughout Central Texas and reconnect communities, businesses and families. And we’re talking about all drivers; we are committed to providing a choice. Those who prefer the non-tolled frontage roads also enjoy an improved commute experience. Our sustainable mobility options give time back to residents so they have more opportunity to do and see the things they value and love. Explore the sites below for more information on our projects, which are designed to meet the diverse mobility needs of our fast-growing region. 183 South Adding capacity and improving airport access with three new tolled lanes and up to three improved, non-tolled lanes in each direction along an 8-mile stretch of US 183 in east Austin.
