Traffic Barriers
Traffic barriers protect workers, guide vehicles, and separate traffic from pedestrians. Transportation Supply offers durable traffic control barriers—from lightweight delineation to high crash-rated options. Browse our traffic barriers for sale for construction sites, road projects, parking lots, and events.
Choose the Right Traffic Barrier for Your Application
Not every traffic barrier is built for the same environment, so selecting the right road barrier starts with your site conditions and safety requirements. For temporary traffic control, water-filled models and plastic road barriers support fast deployment and flexible layouts—especially when you need to shift lanes, close shoulders, or guide vehicles through a work zone. In higher-speed areas, choosing crash-rated traffic barriers can help reduce risk and improve protection for crews and the public.
Key factors to consider include:
- Speed limit and exposure level
- Required crash rating and compliance needs
- Visibility requirements (color, reflective tape, or panels)
- Interlocking features to create a continuous line
- Transport and storage needs (stacking, empty weight, fill-and-drain options)
Plastic Traffic Control Barriers for Work Zones & Events
Water-filled barriers are popular because they’re easy to transport and position when empty, then gain stability once filled. Many models interlock with pins or puzzle-piece connections to create secure runs for lane delineation, channelization, and perimeter control. Common sizes like 32-inch barriers work well for events and general construction, while taller 42-inch options are often used for highway projects and more demanding traffic control setups.
For projects that require frequent changes, plastic barriers are a practical choice with durable, weather-resistant construction. Plastic traffic barriers are designed for quick installation, can be linked together for longer stretches, and can be upgraded with reflective tape for better nighttime visibility. If you need a lightweight plastic road barrier that’s easy to deploy, move, and reconfigure, these plastic road barriers can be an efficient solution that balances safety, cost, and performance.

What types of traffic barriers do you sell?
We offer traffic barriers including water-filled barriers and plastic traffic barriers. These options cover a wide range of needs—from visual separation and channelization to higher crash-rated applications—depending on the model selected.
Are water-filled traffic barriers suitable for high-speed roads?
Some water-filled road traffic barriers are available in higher crash-rated designs, but suitability depends on the specific rating and your project requirements. Always match the barrier’s crash rating and intended use to the roadway speed, exposure, and local jobsite standards.
How do I choose between plastic traffic barriers and water-filled barriers?
Choose based on how you’ll use them: water-filled barriers are ideal when you want lightweight transport with added stability after filling, while plastic traffic barriers are great for quick placement, durability, and frequent repositioning. For either type, consider interlocking features, visibility upgrades, and whether the barrier meets the safety level required for your traffic control plan.
How long do plastic traffic barriers last?
With normal use and proper handling, plastic traffic barriers often last 5–10 years. Lifespan varies by material quality, sun exposure, temperature swings, and how frequently barriers are moved or impacted.
Do you have traffic barriers for sale with fast shipping?
Yes. As a distributor, we source traffic control barriers from multiple suppliers to help keep pricing competitive and improve shipping options. This increases the likelihood that the traffic barriers you need are available closer to your project site to reduce freight costs and delivery times.
How much does a traffic barrier cost?
Traffic barrier cost depends on the type, size, and crash rating. Basic plastic traffic barriers and water-filled models used for channelization are typically the most budget-friendly, while heavier-duty or crash-rated road barrier systems cost more. Your total cost will also vary based on the quantity needed, shipping/freight, and add-ons like reflective tape, panels, or interlocking hardware.
What are the four types of control barriers?
In traffic control, the most common barrier categories are:
- Water-filled barriers (portable, filled on-site for added stability)
- Plastic barriers (lightweight, durable, easy to move and reconfigure)
- Concrete barriers (heavy, long-term use, often used as a protective road barrier)
- Steel barriers (used for high-impact or specialized applications, depending on the system)
What are the road barriers called?
Road barriers are commonly called traffic barriers. Depending on the type and application, you may also hear terms like construction barriers, work-zone barriers, Jersey barriers (often concrete), water-filled barriers, or plastic road barriers. The best term usually depends on the material and whether the barrier is meant for visual guidance, channelization, or impact protection.
