The airport is intended to provide long-term aviation capacity for the Las Vegas metropolitan area, primarily serving domestic, international, charter, and cargo flights.

Clark County Department of Aviation officials are expecting Harry Reid International Airport (LAS) to reach its full capacity of 63 million passengers annually by 2030.

[4][5][6] On June 18,2024, the Clark County Board of Commissioners approved a $1 million contract to retain Landrum and Brown Aviation Consultants to prepare the Environmental Impact Statement for the Southern Nevada Supplemental Airport (SNSA).

[11] As part of the SNSA development, Clark County is initiating a comprehensive expansion of the 27-mile I-15 south corridor between Sloan and Primm, Nevada, with Jean serving as the primary entry point to the new airport.

The expansion will also feature dedicated ramps providing direct access to and from the airport, ensuring seamless travel into Las Vegas and minimizing potential traffic delays.

In conjunction with the airport project, Clark County is also executing a significant utility infrastructure upgrade to bring water, electricity, and reclamation services to the site at Jean, Nevada.
