For over a decade, Alpine Sign has manufactured MUTCD and MDT-compliant road signs and traffic control solutions.
At Alpine Sign, we’ve spent more than a decade doing one thing exceptionally well: manufacturing road signs and traffic control solutions that meet the exact standards Montana requires.
We’re based right here in Missoula, and that matters. We understand Montana’s climate, terrain, and regulations in a way that out-of-state suppliers simply can’t. Our signs are built to handle everything from mountain pass winters to open highway sun, and every one of them meets MUTCD and MDT specifications.
Whether you’re a construction company outfitting a job site, a city or county replacing aging signage, or a private business needing a custom solution — our team is ready to help you get it right the first time.
We manufacture regulatory, warning, and guide signs built to MUTCD and MDT specifications. Every sign is engineered to withstand Montana’s demanding conditions — from high-altitude freeze-thaw cycles to intense summer UV exposure.
Outfitting a construction zone or temporary traffic control plan? We supply the complete range of signs you need to keep workers safe, drivers informed, and your project in compliance. We’ve supplied signage for construction companies across Montana.
We have direct, proven experience working on Montana Department of Transportation bid projects. Our team understands the bid process, the compliance requirements, and what it takes to deliver on time and on spec.
We Know Montana Roads
We’re not a national catalog company shipping generic signs from a warehouse across the country. We’re a Montana business that has been serving Montana communities for over a decade. That local knowledge shows up in every sign we build.
Compliance Is Built In
Every sign we manufacture meets MUTCD standards and MDT specifications. You won’t have to double-check our work or worry about a failed inspection. We get it right so your project can move forward without delays.
Real People, Direct Access
When you call Alpine Sign, you reach an expert — not a call center. Our team includes a General Manager, Shop Manager, and a dedicated MDT bid specialist. You always know exactly who to talk to.
Built for Montana Weather
Our signs are manufactured with materials rated for Montana’s toughest conditions. Whether it’s a mountain highway in February or a sun-baked construction site in July, our signs hold up.
