LAS VEGAS (AP) — The multimillion-dollar expansion of the Las Vegas Convention Center that officials say will allow the city to remain at the top of the list of trade show destinations will have a modern design tied by a ribbon-like roof on the outside and iconic imagery inside.

The board of directors of the agency that promotes Las Vegas will be presented with the final design Tuesday.

The $860 million project involving the construction of a 600,000-square-foot exhibition hall is expected to be completed by January 2021.

Renderings unveiled Monday show replicas of the famous Welcome to Fabulous Las Vegas Nevada sign and marquee of the Stardust hotel at the new hall's atrium.

Chuck Bowling with the Las Vegas Convention and Visitors Authority says input from trade shows was considered in the design.
