On September 19, Governor Jared Polis extended his Safer at Home executive order for thirty days, but he also amended it in a major way — for bars, at least.
Starting on September 21, counties that qualify as Safer Level 1 on the Colorado COVID-19 dial — including Douglas and Arapahoe counties in the metro area — will be able to move their last call to midnight, as long as they observe all the public-health guidelines currently in place for bars and restaurants.
And counties that have reached the Protect Our Neighbors level — Rio Blanco, Mesa, Moffat and Gunnison in western Colorado, as well as Gilpin, home to the gaming communities of Central City and Black Hawk — "may opt out and establish a local last call time, so long as it does not exceed 2 a.m.," Polis's order extension notes.
As for the rest of Colorado's counties, they all land in the Safer Level 2 category, which keeps the current last call of 11 p.m. (Should they slide back to Level 3, however, the last call moves back to 10 p.m.)
The COVID-19 dial not only shows a county's safety level, it also indicates variances within the county that have been allowed by the state. See it here.
