Since 1977, keeping the West's roads safe.
Your Trusted Partner for Safety Supply: Leading the Way Since 1977
Interwest Safety Supply manufactures roadway and highway construction signs and distributes the traffic safety equipment used to signal, protect, delineate, and guide people and vehicles safely through roadways and work zones.
Headquartered in Provo, Utah, Interwest is the largest distributor of traffic safety supplies and the largest manufacturer of roadway signage in the Rocky Mountain region. We operate from five regional locations and two manufacturing facilities across Utah, Colorado, New Mexico, Arizona, and Nevada.
Our products show up in highway and street projects, infrastructure and utility work, development and general construction, events and crowd control, emergencies and natural disasters, and law enforcement, to name a few.
Part of something larger
Local roots. National reach.
Interwest is part of Viant Traffic Solutions, a federation of locally embedded traffic and mobility infrastructure companies. The name on the building is still Interwest, and the people you call are still ours. What changes is the depth behind them: shared expertise, a broader supply chain, and the backing of a national network.
