Austin-Bergstrom International Airport New Midfield Taxiways

The City of Austin’s Aviation department is reimagining Austin-Bergstrom International Airport through a comprehensive, multi-year airport expansion program to accommodate record-breaking passenger and airline activities. RS&H serves as the lead airport engineering firm for the New Midfield Taxiways project, providing project management, preliminary engineering, design, construction administration, and FAA Resident Project Representative (RPR) for the Journey With AUS Expansion & Development Program.

At the heart of airfield infrastructure improvement are the two parallel Airplane Design Group (ADG) V, Taxiway Design Group (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 improve airfield connectivity, facilitate aircraft movement and provide essential access to future terminal development.

To facilitate the program’s construction impacts on aircraft gates, Remain Overnight parking (RON) and diversion parking, the Maintenance Ramp Expansion project was added to the New Midfield Taxiways contract to expand the existing Maintenance Ramp. This expansion to the east will accommodate six ADG III aircraft parking at a future Concourse M (CCM) and will be reconfigured and remarked to allow for optimization of aircraft parking at the expanded ramp. The project also includes lighting improvements to install six new mast lights to illuminate the expanded ramp and replace three existing mast lights. Utility improvements include a proposed corridor between the expanded ramp and the future Concourse M building footprint, providing pathways for utilities needed to support Ground Service Equipment (GSE) at each of the six aircraft parking positions.

The construction of the two parallel taxiways and maintenance ramp expansion are underway, connecting Taxiway C in the west to Taxiway B in the east, and includes substantial modifications to utility and storm sewer systems. These projects will significantly improve airfield connectivity, mitigate program-wide construction impacts, and support smoother and more efficient aircraft operations across the airport.

RS&H’s leadership in the Envision verification effort reflects the project team’s commitment to sustainable airport infrastructure, including the use of Type IL cement, native landscaping, and enhanced stormwater management systems. The New Midfield Taxiways and Maintenance Ramp Expansion project is scheduled for completion in spring 2027.

With each meticulously engineered element, from ramp pavement to 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 Austin-Bergstrom International Airport’s airfield into the future of their development.
