Travelers to Pittsburgh International Airport be alert: Road construction into the airport complex begins this week as work continues on the $1.4 billion new terminal expected to open in spring 2025.

Starting May 23, the Interstate 375 West ramp is reduced to one lane and the airport entry road is reduced from three lanes to two. Signs directing drivers to airline arrivals, departures and parking are being updated as part of the construction of the new roadway. 

Travelers are encouraged to allow extra time to navigate around some of the road changes, although all airport operations and services remain accessible, according to the Allegheny County Airport Authority.

Work already has started inside the Airside Terminal around the escalators to and from the tram; scaffolding has been erected on both sides of the pairs of escalators and passengers are directed around the interior core when making their way to their gates. 

Construction reached a milestone earlier in May when the last steel beam was readied for the roof of the new terminal. More than 100 governmental and business leaders and 300 authority employees gathered at the site for a “topping out” ceremony, when they signed one of the final beams that will be raised into place this summer, according to Blue Sky News, the authority’s news service.

The Terminal Modernization Program includes a new Landside Terminal, a 5,000-space parking garage and new airport road system. The aim of the project is to build a new terminal that better fits the number of flights that now serve the region.

The project is expected to be 50% completed in the next few months.
