When you’re responsible for a work zone, you don’t get many second chances. The right barricade makes it obvious where traffic needs to stop, turn, or stay out—keeping your crew protected and drivers confident.
Type 3 barricades (often written as Type III barricades) are the go-to choice for high-visibility traffic control, especially when you need to close a lane or an entire roadway. At Trans Supply, we stock Type 3 barricades that are made to hold up on active jobsites—durable rails, bold reflective panels, and the footprint you need to command attention day or night.
If you’re not sure which barricade type your site calls for, reach out. As an owner-run business, we’d rather help you get it right than sell you the wrong thing.
Type 3 Barricade Dimensions & Specs
Type 3 barricades are designed with three horizontal rails and high-visibility reflective panels, making them one of the most recognizable and effective tools for traffic control. Most Type III units are built in standard widths (typically 6–8 feet) with an overall height of roughly 3–4 feet, providing a broad, highly visible closure that’s easy for drivers to identify—especially at speed or in low light.
They’re commonly used with “ROAD CLOSED,” “DETOUR,” and directional signage to create clear, compliant closures. Whether you’re planning a short-term closure or staging a longer project, Type III barricades help you create a setup that drivers can understand quickly, while the larger rail surface area and standard sign-ready layout make it simple to mount guidance and detour messaging where it will be seen.
Type 3 Barricade Applications
Type 3 barricades are a workhorse for traffic safety. Here are some of the most common ways customers use them:
- Construction Sites: Block off full access points, protect equipment movement zones, and create unmistakable “no entry” boundaries.
- Road Work & Utility Crews: Ideal for lane closures, detours, and full road shutdowns where visibility and authority matter.
- Events & Crowd Control: Direct vehicles and foot traffic, close streets for festivals, parades, and venue operations.
- Schools & Municipal Use: Useful for emergency closures, temporary restricted areas, or special traffic patterns during activities.
If your goal is to make the message unmistakable—Type 3 is usually the right call.

Type 3 Barricades FAQ
Our customers ask great questions about Type 3 barricades because the right setup can make or break a safe, compliant work zone. Here are the most common questions we hear—along with straightforward answers to help you choose with confidence.
What is a Type 3 barricade?
A Type 3 barricade is a traffic control barricade built with three horizontal rails and reflective sheeting for maximum visibility. It’s commonly used for road closures, detours, and lane restrictions, where drivers need to see and understand the closure from farther away.
When to use Type 3 barricade
Use a Type 3 barricade when you need a strong, clear closure message, especially at road closed points, detour entrances, on high-speed roadways, during longer-duration work zones, or in any setup where a Type 1 or Type 2 feels too small or too easy to miss. If the closure must be obvious at a glance, Type 3 is typically the safest choice.
How long are Type 3 barricades?
Most Type 3 barricades are designed to span a meaningful width of roadway presence and are commonly found in the 6–8 foot range, depending on the model and rails. If you tell us your use case (full closure vs. taper vs. driveway access), we can help you choose the right size and quantity.
What is the difference between Type 2 and Type 3 barricades?
The biggest difference is size, visibility, and intended use. Type 2 barricades are generally smaller and lighter, so they’re often used on side streets, local roads, and smaller work areas. Type 3 barricades are larger with three rails, creating a more authoritative visual barrier that’s ideal for road closures, detours, and higher-speed traffic environments. In short, Type 2 is great for lighter-duty traffic control, while Type 3 is built for situations where drivers simply can’t miss the message.
Should Type 3 barricades be used to close or partially close a road?
Type 3 barricades are most commonly used to close a road or lane, especially when paired with proper signage (like ROAD CLOSED or DETOUR). They can also be used for partial closures (such as blocking one lane or restricting access) when you need high visibility and clear direction. The right choice depends on your traffic control plan, signage needs, and whether vehicles must be fully prevented from entering the area.
