Overhead gantry and cantilever structures play a crucial role in modern traffic management systems. These structures are designed to support traffic signboards, directional signage, and electronic display systems, ensuring clear visibility and effective communication for road users.

Overhead Gantry

An overhead gantry is a robust steel structure installed across the full width of the roadway. It is commonly used on highways and expressways to mount large directional signs, lane control signals, and variable message displays.

Key Features of Overhead Gantry

• Provides clear visibility of signs across all lanes
• Ideal for highways, flyovers, and multi-lane roads
• Strong structural design to withstand wind and weather conditions
• Ensures uniform guidance for all road users
• Long-lasting and low maintenance

Cantilever (Canlever) Structure

A cantilever structure is installed on one side of the road and extends horizontally over the carriageway. It is commonly used where full-span gantries are not feasible due to space constraints or cost considerations.

Key Features of Cantilever Structures

• Cost-effective alternative to overhead gantries
• Suitable for single or dual-lane roads
• Efficient use of roadside space
• Provides excellent sign visibility without obstructing traffic
• Designed for durability and structural stability

Applications

• Highways and expressways
• Urban roads and flyovers
• Toll plazas
• Industrial and commercial zones
• Smart traffic management systems

Overhead gantry and cantilever structures significantly enhance road safety by improving visibility of traffic information, reducing driver confusion, and supporting efficient traffic flow.
