Lattice Towers Built for High-Voltage Transmission Projects
Drivers depend on clear, well-supported signage to navigate interchanges, lane changes, and toll points safely. Behind every highway overhead sign is a structure that has to carry significant wind and dead load, resist fatigue from constant traffic vibration, and stay in service for decades without failure.
MICA Steelworks designs and fabricates highway sign structures for state DOTs, toll authorities, and highway contractors across the United States. Our AISC-certified plants and TxDOT DMS-7380 qualification give agencies confidence that every structure meets the standards required for public roadway infrastructure.

Overhead Sign Structures Built for Interchanges and Corridors
Roadway signage comes in many forms, each with its own span, height, and mounting requirements. Our road sign structures are engineered to meet the load and clearance demands of high-traffic corridors.
As a U.S.-based manufacturer with decades of experience, MICA Steelworks delivers:
- Cantilever Overhead Sign Structures (COSS) for single-side mounted signage
- Overhead Sign Bridges (OSB) spanning multiple lanes
- Balanced Tee Structures for roadways and electronic messaging boards
- Traffic and toll monitoring structures, including camera and monitoring poles
Each structure is fabricated with tight tolerances and engineered to hold up under real-world wind, vibration, and long-term fatigue loads.

Full Range of Highway Overhead Sign Structure Configurations
Every roadway brings its own span, clearance, and load requirements. Our team designs and fabricates a wide range of overhead cantilever sign support structures to match specific project needs.
Available Structure Types
- Cantilever Sign Structures for Single-Side Roadway Mounting
- Overhead Bridge Sign Structures Spanning Multiple Lanes
- Balanced Tee Structures for Electronic Messaging Boards
- Traffic and Toll Monitoring Structures
- Camera and Monitoring Poles
- Multi-Sided Tubular Poles, I-Beam Trusses, and Pipe Trusses
We fabricate in multi-sided tubular, I-beam and angle truss, and pipe and four-sided tubular configurations, with spans designed for concrete or other support structures.

Engineering That Holds Up Under Traffic Loads
A highway overhead sign carries more than its own weight. Wind loading, vibration from passing vehicles, and long-term fatigue all factor into a safe design. MICA Steelworks approaches every sign structure project, alongside our work in commercial light poles, with a focus on structural integrity and constructability.
We consider:
- Wind loading and fatigue design across span lengths
- Foundation compatibility and anchor bolt precision
- Standardization of parts to reduce field labor costs
- Coordination with signage, lighting, and monitoring equipment
Durable Finishes for Long-Term Roadway Performance
Highway structures stay in service for decades, often with heavy exposure to road salt, moisture, and UV cycling. To protect that investment, we offer a range of finishes for every road sign structure we fabricate:
- Hot-Dip Galvanizing (In-house)
- Self-Weathering Steel
- Epoxy Painted Coatings
- Powder Coating Systems
- Paint Over Galvanizing
A Reliable Partner From Design to Delivery
Highway projects require coordination, responsiveness, and accountability at every stage. MICA Steelworks combines decades of experience with a hands-on, collaborative approach that keeps projects moving. Supported by in-house galvanizing and U.S.-based manufacturing, we maintain control over quality, timelines, and coordination from design through delivery.
Our team works closely with DOT engineers, contractors, and procurement teams to:
- Provide clear communication throughout the project life cycle
- Deliver fabricated structures on schedule
- Adapt to design changes or corridor-specific field conditions
- Support coordination across engineering, fabrication, and logistics
This same approach carries across our work in transportation structures and custom steel solutions, giving DOTs and contractors a single fabrication partner across an entire corridor.
