hazardous materials

I commute from northern Colorado to Denver, mostly on I-25 between US-34 and the Park avenue exit. I have been noting hazardous material placards since 2025-04-24. Here’s what I’ve seen.

Other weird stuff on I-25

Today I reached a personal best while spotting hazmat placards.

UN 3328, Radioactive material, Type B (U) package, fissile.

I’ve been commuting somewhat less than 3 days a week, from Fort Collins to Denver and back. I’ve seen some mighty strange stuff.
