Sky Harbor Taxiway Sierra
As a major subconsultant to the Kiewit Western/Dibble & Associates team, we provided structural design management and engineering services for the reconstruction of Taxiway Sierra at Sky Harbor International Airport in Phoenix. The design-build project involved the demolition of three existing short-span taxiway bridges and the design of a new five-span taxiway bridge across Sky Harbor Boulevard. The new bridge was designed to accommodate Group V aircraft with wingspans between 171 and 214 feet.
The owner requested that the finished structure be aesthetically compatible to existing infrastructure and provide a maintenance-free, cost-effective replacement solution. Another important component of the project was to minimize interruptions to airside and landside operations during construction. Our designers also had to consider proposed future improvements, including the addition of an automated people mover under the taxiway.
Additional components addressed by the team included taxiway reconstruction; apron infill; infield pavement; lighting, signing and striping; airport service roads and traffic control; grading, drainage and utilities.
