Phoenix Sky Harbor Terminal 4 Expansion Set To Start In May 2019

With expansion plans in place for a new concourse at the Phoenix Sky Harbor International Airport, the contractor in charge of the project is familiar with Sky Harbor.

The $310 million project that will begin at Terminal 4 next year will be handled by McCarthy Building. Based in St. Louis, Missouri, the general contracting company has an office in the Valley and previously assisted in the Terminal 3 expansion of Sky Train and also worked on another Terminal 4 project.

Home to Southwest, American Airlines, British Airways and others, the terminal is the largest and busiest at Sky Harbor. Eight Southwest gates will be added as part of the expansion.

“Our teams are well acquainted with the nuances of managing a construction project at a busy airport,” Justin Kelton, president of McCarthy’s southwest region said, pointing to the previous work at Sky Harbor.

It was announced by city officials last year that the 130,000-square foot concourse would be used by Southwest.

The plans include a connector bridge across Sky Harbor Boulevard, along with another bridge that provides D concourse access. 

Included in the expansion of Checkpoint D will be more ticket counters, a baggage carousel and concessions.

86 gates and more than 80 percent of the airport’s passengers utilize Terminal 4.

Since 2017, the airport has served a total of 43,921,670 passengers.

The construction is slated to begin in May and conclude in early 2022. Other parts of the terminal will see minimal impact from the project.
