The International Gates Expansion was unique in nature wherein it connected two Airport Terminals via an underground tunnel. By connecting the two terminals, Customs Border Patrol was able to expand the ‘Sterile Area’ from Terminal 3 to D-Gates thus expanding incoming international flights to D-Gates.

At the D-Gates connection point, a three-story building was constructed with structural concrete walls and composite concrete slab on decks. The interior of the building included a 100’+ Escalator, (2) two-stop Elevators, (4) 180’ Moving Walkways, Ceramic and Glass Wall Tiling, Terrazzo Flooring, Stainless Steel Cladding, curved metal wall panels with custom curved LED light fixtures by Selux, custom wallpaper screen printed with real vintage photos of Las Vegas, and backlit advertising signage that show-cased Las Vegas. The exterior of the three-story building was wrapped with metal composite wall panels to match existing finishes at D-Gates.

The interior of D-Gates were also remodeled to meet the CBP standards of maintaining a ‘Sterile’ area for incoming international passengers until they passed ‘Custom’s screening. A glass wall was built to enclose the arrival gates, so passengers only had one choice of moving through the newly built tunnel towards Terminal 3 CBP. Doors were equipped with Access Control Devices by Johnson Controls that were timed according to Fire Code and Security Standards. The Sterile Corridor also included Terrazzo Flooring, new Acoustic Ceiling Tile, reconfigured HVAC ductwork, and new CBP Signage.

The Structural Concrete Tunnel included: Excavating 40’ wide by 30’ deep by 1000’ long trench extending from Terminal 3 to D-gates. It included Grace Waterproofing System; Kone Moving Walkways, Elevators, and Escalator; Terrazo Flooring System; Glazing Storefront, as well as Glass and Stainless Steel Cladding and Handrail System; Wall Tile and Custom Printed Wallcovering; Smoke Control System with 4 Fire Wall Curtains.
