Clark County aviation officials outlined a sweeping modernization plan for Harry Reid International Airport this week. The multibillion‑dollar overhaul will expand capacity, replace aging infrastructure, and prepare Las Vegas for continued visitor growth and major events.

According to the Las Vegas Review-Journal, Clark County Aviation Director James Chrisley recently told the Clark County Commission that much of the airport was built for the passenger volumes and aircraft of the 1990s and early 2000s, saying that Las Vegas’ rise as a global destination for sports and mega‑events requires facilities capable of handling today’s traffic and future growth.

Planners outlined a long list of upgrades designed to serve as a bridge to a future two-airport system, with a proposed commercial airport in the Ivanpah Valley still at least a decade away.

There is no finalized timeline or cost estimate yet, though officials expect to announce a price tag sometime next year.

Reid, now the nation’s eighth-busiest airport, is preparing to increase its Terminal 1 gate count from 39 to roughly 65, building a wing of around 11 Terminal 1 gates near the former Terminal 2 site. Once operational, crews will convert the aging A and B gate “satellite” layout into a linear pier design, increasing those gate counts from 23 to about 33.

A new administration building and parking garage will follow, and Terminal 3 will be renumbered as Terminal 2.

One of the most visible changes will be a new vertical circulation system at Terminal 1. New escalators and elevators will eliminate the need for passengers to cross a busy taxi lane when moving between baggage claim and the parking garage. Taxi and ride-share staging areas will also be relocated to improve pedestrian safety and free up garage space, adding roughly 330 parking spaces during peak travel periods.

Planning is also underway for a new Customs and Border Protection facility and charter ramp on the airport’s west side, intended to better accommodate international private aircraft tied to major events such as Formula One.
