Just off the Las Vegas Strip, and within the footprint of the world’s tallest observation wheel, contractors’ weekly lifts of massive 315-ft-long steel trusses are key features of the $375-million Caesars Forum project. Developers say the sprawling convention center will contain two of North America’s largest column-less ballrooms.

Located in a former parking lot, Caesars Forum will total more than 500,000 sq ft when completed in early 2020. The facility will have not one, but two massive column-less ballrooms arrayed west to east. Both ballrooms will have movable dividers to split the space if necessary. The west ballroom is steel pier construction and a single story. The east ballroom will be similar, but with underground area for parking and storage. Total size of the flexible meeting space in the combined ballrooms will be about 300,000 sq ft. There are also two smaller ballrooms.
