Plumb Signs Inc. was proud to play a key role in rebranding the iconic Seattle Convention Center. Formerly known as the Washington State Convention Center, the venue was recently renamed "The Arch" to reflect Seattle’s evolving civic identity. Our custom signage solutions helped mark this transformation and reinforced the vibrancy of the space.
This project exemplifies Plumb Signs’ commitment to delivering impactful, community-connected signage — from structural design to visual storytelling.
Key Achievements

Phase 1
- Removing Old Signs: We safely dismantled outdated signage to make space for a fresh visual identity.
- Building Signs: New, eye-catching signage helped reinforce the center’s updated branding.

Phase 2
- Parking Garage Signs: Designed and installed clear signage to improve navigation and accessibility.
- Exterior Signage: Branded architectural elements that matched the new name and look.
