Find the Best Traffic Barriers Near You

Traffic barriers are tools used to keep vehicles within the roadway and keep them safe from potentially dangerous situations, such as an ongoing construction near the highway. They are designed to protect road users, from pedestrians and drivers to workers on a construction site.

Below are four types of traffic barriers according to their functions:

• Roadside Barriers - These are used to ensure traffic is protected from any roadside obstacles or hazards. These may include steep slopes, fixed objects such as bridge priers, and even bodies of water.

• Median Barriers - This type of barrier prevents vehicles from crossing road medians and colliding with oncoming vehicles. They are designed to be stuck from either side. Median and Roadside barriers can actually be used together in the prevention of vehicles and hazards within the median from colliding.

• Bridge Barriers - Placed on the bridge to help restrain vehicles from crashing off the side of the structure then falling onto the roadways, rivers or railroads below. It is designed higher than a roadside barrier because it not only stops vehicles from accelerating but also from falling over the bridge. They are usually made from reinforced concrete parapets and barriers or multi-rail tubular steel barriers.

• Work Zone Barriers - These barriers are usually seen near work zones. Its main purpose is to protect all road users from the potential hazards of the work zones such as construction sites, road repairs and others. Work zone barriers come in two types: water-filled barrier and temporary concrete barrier. Water-filled barriers are steel-reinforced plastic boxes that are linked together, forming a longitudinal barrier then ballasted with water. These can be easily placed where needed because it will not need any heavy-lifting. However, it is not recommended for use during freezing weather.

Below are the different types of road barriers based on their stiffness:

• Flexible Barriers - These barriers are usually made from wire rope that is supported between frangible posts. It is best used to minimise injuries to vehicle occupants but at the same time poses a risk to motorcycle drivers. Since this type of barrier deflects more effectively than other barrier types, it needs to be repaired immediately following the impact. This is to maintain their redirective capability.

• Semi-Rigid Barriers - This type of barrier is made from steel beams or rails. These may deflect less than flexible barriers, but they can actually be located closer to the hazard, especially when space is limited. These may also be able to redirect secondary impacts, depending on the impact.

• Rigid Barriers - These barriers are made of concrete, and unlike the previous barriers mentioned, these do not deflect. Therefore, rigid barriers must only be used when there is no room for deflection and both semi-rigid, and flexible barriers cannot be used. It requires little to no maintenance and can be used to provide a high level of containment of heavy vehicles. Plenty of these barriers will be seen when utilised on road worksites to ensure the protection of workers and other road users while another barrier type is under repair.

The cost of hiring traffic barriers varies depending on the type, quantity and hire duration. On average, daily hire rates can range from $5 to $30 per barrier for plastic or water-filled types and up to $50 to $100 for heavier concrete barriers. Prices may vary based on location and supplier. Use our Get a Quote tool to get a customised quote based on your project from one of our suppliers today!

Yes, traffic barriers come in various sizes to suit different requirements. Common sizes include 1-metre, 1.5-metre, and 2-metre lengths. The height and width can also vary, with some barriers designed for low-impact zones and others for high-traffic areas with greater height and sturdiness.

Absolutely. Traffic barriers are versatile and can be used for road safety and pedestrian control. Concrete and water-filled barriers are often used to separate vehicle traffic from pedestrian areas, while steel barricades and plastic barriers are more suitable for guiding foot traffic and creating safe walkways.

Traffic barriers can be hired for short-term events, such as a few days, or long-term projects lasting several months or more. Hire duration flexibility depends on the supplier, with some offering both short-term and long-term hire options.

Installation requirements for traffic barriers vary depending on the type. Concrete barriers may require lifting equipment due to their weight, while water-filled and plastic barriers are lighter and can be manually positioned. Proper alignment and securing are essential to ensure safety and effectiveness.

Yes, traffic barriers are designed to be highly effective in high-traffic areas. Concrete barriers, particularly, are robust and provide strong protection against vehicle impacts, making them suitable for highways and busy roads. Water-filled and steel barriers also effectively manage traffic flow and enhance safety in busy areas.

A variety of traffic barriers are available to manage vehicle flow, protect work zones, and enhance road safety. Common types include:

• Concrete barriers – permanent or temporary, ideal for high-impact protection.
• Water-filled barriers – lightweight when empty, portable, and often used in temporary worksites.
• Plastic barriers – modular, easy to move, and suitable for short-term traffic management.
• Steel or metal barriers – durable, often used on highways or bridges for crash protection.
• Cable or wire rope barriers – flexible, absorb impact, and commonly used along medians or highways.

The choice depends on traffic volume, site conditions, duration of use, and safety requirements.

Yes, most traffic barriers can be linked together to create a continuous line of protection or separation. Many concrete, plastic, and steel barriers feature interlocking connectors or built-in coupling systems that allow units to be securely joined.

Linking barriers ensures stability, eliminates gaps, and provides consistent protection along roads, construction zones, or event sites. Correct installation is essential to maintain structural integrity and compliance with traffic management standards.

Yes, traffic barriers are suitable for highways, provided they are designed for high-speed and high-impact conditions. Concrete, steel, and cable barriers are commonly used on highways to separate lanes, protect work zones, and prevent vehicles from crossing medians.

Highway barriers must meet strict safety standards, including impact resistance, height, and strength specifications. Proper installation ensures driver safety, effective traffic management, and compliance with road authority regulations.

Traffic barriers are installed using methods suited to their type, weight, and the site’s traffic conditions. The process generally includes:

• Delivery and positioning – barriers are transported to the site and placed along the designated alignment.
• Linking or interlocking – modular or interlocking barriers are connected to form a continuous line.
• Securing – heavy barriers may be anchored, and water-filled barriers are filled for stability.
• Final checks – ensuring alignment, stability, and compliance with traffic management plans.

Proper installation ensures effective traffic control, enhanced safety, and minimal disruption to road users.
