Idaho Follows Colorado In Replacing 420 Mile Marker

If you plan on stealing a 420 mile marker, you won’t find one in Idaho.

Transportation officials say Idaho’s 420 mile marker has been replaced with a 419.9 sign to deter marijuana enthusiasts. Adam Rush of the Idaho Transportation Department says this is the only 420 sign that has been replaced, because most highways don’t cover more than 400 miles.

Colorado replaced its mile marker last year with a 419.99 sign after the 420 sign was stolen after multiple thefts, according to CDOT.

The number 420 has long been associated with marijuana.
