Project Profile

Sky Harbor Airport Trench

At the Phoenix Sky Harbor International Airport, total passengers served averaged over 40,000,000 per year through 2019. Total takeoffs and landings averaged over 425,000 per year.

Several large construction projects have been occurring at the Sky Harbor Airport over the last decade. The purpose of these projects is to improve the airport’s infrastructure, which has required large amounts of cast iron trench products.

Sky Harbor has been in the process of reconstruction since 2013. The project has included: 

  • Terminal modernization, demolition, and replacement
  • Taxiway construction
  • Maintenance expansion
  • Construction of a transport rail system

Approximately 5,500 feet of Neenah Foundry 4993 series trench was specified on the project to date. Additional trench will be needed for future expansion.

Neenah Foundry began delivering products for the project beginning in 2016. Deliverables include:

  • Design drawings, certifications, installation guides
  • 4,500 feet of 4993-DAB trench
  • 240 feet of 4993-DAH hinged trench

The 4993 trench frames and grates installed at Sky Harbor International Airport became the standard specification for the airport. The trench has been performing as designed and will continue to be used at the airport for future projects.
