Can Sin City’s new Gateway Arches outshine the Welcome to Las Vegas sign? Mary Forgione, L.A. Times · November 20, 2020 at 7:20 am Las Vegas has a new downtown landmark — the Gateway Arches. The recently installed 80-foot-high twin interlocking steel arches dangle a seven-ton, pink retro-style City of Las Vegas emblem framed by more than 13,000 LED lights. That’s a lot of bling. The lights went on for the first time Wednesday at the northern end of Las Vegas Boulevard between St. Louis and Bob Stupak avenues at the base of the Strat Hotel, Casino & SkyPod. It’s at the opposite end of the Strip from the 1959-era Welcome to Las Vegas sign, which technically is outside the city limits. By day, the sleek arches are deep blue; by night, they light up in various colors.
