Capability

Sign Manufacturing

We build the signs we sell.

Interwest is the largest manufacturer of roadway signage in the Rocky Mountain region and a 3M Certified Sign Fabricator. The regulatory, warning, guide, and custom signs you order are made to MUTCD standards in our own facilities, on a schedule we control.

What we make

Roadway Sign Manufacturing & Custom Signs


  • Regulatory and MUTCD signs
  • Construction and work-zone signs
  • Warning and guide signs
  • School and pedestrian signs
  • Custom and specialty signs
  • Sign hardware, posts, and stands

Made here. Held to standard.

When the sign is made in-house, you are not waiting on a third party and you are not guessing on compliance. Our fabrication runs to MUTCD specification, and our 3M certification means the sheeting and retroreflectivity meet the grade your project calls for.

If it is not on the chart, we can still make it.

Need a one-off message, a private-property sign, or a special size? Our custom sign team handles short runs and specialty fabrication. Send us the spec and we will quote it.
