Colorado officials say mile marker 420 on Interstate 70 has been stolen for the last time.
Amy Ford of the Colorado Department of Transportation says the "MILE 420" sign near Stratton has been replaced with “MILE 419.99.”
MILE 420 just east of Stratton was last stolen in spring 2013.
Colorado legalized recreational marijuana sales this year and Ford says the number, long associated with marijuana, had to go.
About 25 miles from the border of Kansas, most highways aren’t even long enough to have a “420” marker. U.S. 40 and U.S. 50 are both long enough for a 420 mile marker, but neither have signs, according to Google Street View.
MILE 420 wasn’t the only problematic number to be stolen in the state.
Colorado’s Cameron Pass in Larimer County has a "MILE 68.5" sign after frequent thefts of the "MILE 69" sign.
