These structures allow traffic signs to be clearly visible across multiple lanes.

Gantry sign structures are a vital component of modern expressway infrastructure, designed to provide clear, high-visibility guidance to drivers traveling at high speeds. These overhead structures span across multiple lanes, ensuring that critical information such as directions, exits, lane usage, and safety instructions is visible to all road users.

What are Gantry Sign Structures?

Gantry sign structures are large overhead frameworks, typically fabricated from galvanized steel or aluminum, installed across highways and expressways. They support sign panels that display directional, regulatory, and informational messages to drivers. These structures are engineered to withstand heavy wind loads, vibrations, and extreme weather conditions while maintaining long-term durability.

Key Features

• High visibility across all lanes due to elevated placement
• Durable construction using galvanized steel or corrosion-resistant materials
• Retro-reflective signage for excellent day and night readability
• Weather-resistant design suitable for harsh environments
• Custom fabrication based on road geometry and requirements
• Compatible with ITS systems like VMS, cameras, and sensors

Types of Gantry Structures

Full Span Gantry: Covers the entire width of the roadway, ideal for wide expressways and multi-lane highways.

Cantilever Gantry: Supported from one side, suitable for locations with limited space.

Portal Gantry: Supported by columns on both sides, commonly used at toll plazas and junctions.
