New Orleans International Airport Taxiway G

Following the 2019 opening of the new terminal at the New Orleans International Airport, the New Orleans Aviation Board received FAA approval to extend Taxiway Golf (G) and Bravo (B) to accommodate larger International Flights. Given the location of Taxiway G near the perimeter of the Airport grounds, several drainage improvements/changes were also required as part of the design and construction of the Taxiway Extension.

As a sub to Garver, MSMM was tasked with preparing the taxiway pavement restoration design, designing the utility relocations, developing the transit pavement design, designing the drainage improvements, and applying for the appropriate FAA permit applications. For the taxiway pavement, over 600,000 sf of new pavement was designed. For the drainage infrastructure, our team evaluated the drainage impacts of the Taxiway extensions through hydraulic modeling, and designed drainage mitigation features inclusive of canal enclosures and concrete box culvert enclosures (pictured below). Our utility relocations design consisted of a main sewer artery, FAA conduit and Parish and Airport water lines. Finally, we were responsible for designing changes to the Airport perimeter fencing due to the taxiway extension. Project design was completed in May of 2020 and the project was bid in June of 2020.  Construction began in October of 2020 our team has provided construction administration resident inspection and construction management services during the construction phase.
