Austin-Bergstrom International Airport Midfield Taxiways

Airport expansion & development program midfield taxiways and associated infrastructure

The City of Austin is reimagining its airport with a comprehensive, multi-year airport expansion program to accommodate record-breaking passenger and airline activities. RS&H is an integral partner in the Journey with AUS program, as the lead engineering firm for the Midfield Taxiways project, providing project management, preliminary engineering, design, construction administration, and FAA Resident Project Representative (RPR) for the Airport Expansion & Development Program (AEDP).  

At the heart of this transformation are the two parallel ADG V, TDG 6 midfield taxiways, Taxiway N and Taxiway P, each stretching approximately 4,170 feet connecting the east and west sides of the airfield and will accommodate unrestricted maneuvering for widebody aircraft, such as the Boeing 777-300. To streamline access to future concourses and further augment maneuvering capabilities, the project introduces one connector Taxiway N2 (western) and plans for another Taxiway N1 (eastern). These taxiways serve a dual purpose, facilitating aircraft movement and providing essential access to future development.  

The construction of the two parallel taxiways is underway, connecting Taxiway C in the west to Taxiway B in the east, and includes substantial modifications to utility and storm sewer systems. The new taxiways will significantly improve airfield connectivity, facilitating smoother and more efficient aircraft movements. RS&H’s leadership in the Envision verification effort attributes a commitment to sustainable practices, including using Type 1L cement, native plant landscaping, and improved stormwater infrastructure. The Midfield Taxiways project is scheduled for completion in 2026. 

With each meticulously engineered element, from taxiways to taxiway bridges, and an unwavering commitment to environmental stewardship, the project promises to usher in a new era of engineering efficiency, access, and sustainability for air travelers and the city of Austin. This ambitious engineering endeavor embodies the spirit of progress and innovation that propels our world forward. Together, we are engineering the AUS airfield into the future of their development.
