LAS VEGAS (AP) – Fireworks in the skies and stars on stage will mark an annual New Year’s Eve celebration that started two decades ago to draw revelers to the Las Vegas Strip.

“America’s Party” organizers expect 330,000 visitors, and police say they’re prepared for 400,000 during the 2020 event that officials are dubbing “The Big 20.” Las Vegas Boulevard will be closed Tuesday night ahead of a choreographed eight-minute aerial pyrotechnic display at midnight from atop seven casino resorts.

The downtown Fremont Street Experience will debut a $32 million upgrade to a canopy light and sound show above its five-block carnival-like pedestrian midway. It features stages with live bands and DJs.
