When you see a road crash barrier standing strong along a highway, protecting drivers and pedestrians, it’s easy to take it for granted. But behind every barrier is a detailed, methodical process involving careful planning, precision engineering, and expert craftsmanship.

At McIntosh Fencing, we’re proud to take projects from concept to construction — delivering high-quality, reliable barrier systems that help save lives. Here’s a look behind the scenes at the journey every road crash barrier takes before it’s ready to perform when it matters most.

Every project starts with a conversation.

We meet with clients — whether councils, civil contractors, or private developers — to understand the specific needs of the project:

• What type of road is it (rural, urban, highway)?
• What traffic volumes and speeds are involved?
• Are there specific hazards, like sharp curves, intersections, or wildlife crossings?
• What regulations and standards need to be met?

Next, we conduct a detailed site assessment, inspecting the road conditions, surrounding environment, and any potential risks. This information helps us choose the most effective barrier system for the location.

After gathering all the necessary information, we move into design and planning.

Here’s where the expertise of McIntosh Fencing really comes into play. We carefully design the barrier layout to:

• Maximise driver and pedestrian safety
• Meet or exceed Australian standards (such as AS/NZS 3845)
• Suit the local landscape and drainage conditions
• Ensure future maintenance and access needs are considered

At this stage, we also factor in practicalities such as material selection (e.g., W-beam guardrails, wire rope barriers, or concrete options), surface preparations, and integration with other road safety features.

Once the design is finalised, we work closely with stakeholders to gain necessary approvals. This may involve liaising with local councils, road authorities, and engineering consultants.

After approvals are secured, we schedule the construction phase, carefully coordinating with other trades and contractors to ensure minimal disruption to traffic and efficient project delivery.

Before installation begins, the site must be properly prepared.

Our team ensures:

• Accurate measurement and marking of barrier placements
• Proper excavation and setting of foundations for posts
• Attention to drainage and soil stability

Foundations are critical to the strength and durability of the barrier — and we never cut corners. Every post must be perfectly aligned, spaced, and secured to ensure the barrier can perform under real-world impact conditions.

With foundations ready, the real craftsmanship begins. Our skilled installers work with precision to:

• Securely fix posts into place
• Attach rails, wire ropes, or panels to meet exact tension and alignment specifications
• Install end terminals, crash cushions, or transitions where needed

Every nut, bolt, and connection is checked and double-checked. We know that when it comes to road safety, attention to detail saves lives.

Once installation is complete, we conduct a comprehensive inspection to ensure every aspect of the barrier meets our strict quality standards — and regulatory requirements.

Only when we’re 100% satisfied do we hand over the completed project to the client, along with all necessary documentation and certifications.

At McIntosh Fencing, the journey from concept to construction is about more than just ticking boxes — it’s about protecting communities, drivers, cyclists, and pedestrians every day.

Our commitment to quality workmanship, expert advice, and personal service sets us apart. Whether you need a barrier for a rural road, a busy highway, or a temporary construction zone, we’ll be with you at every step — delivering a solution you can trust.

Road crash barriers are something we often drive past without a second thought — but their impact on road safety is profound. From humble beginnings to highly engineered systems, road barriers have evolved alongside our growing need for safer, smarter infrastructure.

At McIntosh Fencing, we’ve seen firsthand how these systems have changed over time — and we’re proud to play a part in delivering the latest, most effective barrier solutions across Australia. Here’s a closer look at how far we’ve come… and what the future may hold.

In the early 20th century, as vehicles became faster and more common, so too did road accidents. The first barriers were rudimentary — typically made from timber or stone, with little engineering behind them. They served more as psychological deterrents than actual safety features.

It wasn’t until the mid-1900s that metal guardrails began to appear. These steel barriers were bolted into the ground and designed to prevent vehicles from running off the road — though they were often rigid and unforgiving during collisions.

With more research into crash dynamics and vehicle behavior, road safety authorities began developing energy-absorbing barriers — systems that not only stopped vehicles, but reduced the force of impact on occupants.

Innovations during this time included:

• W-beam Guardrails: Designed to absorb energy and redirect vehicles.
• Concrete Barriers: Strong and effective in preventing crossover accidents, especially on highways.
• Wire Rope Safety Barriers (WRSB): Introduced as a more flexible option, absorbing impact and reducing serious injuries.

These decades also saw barrier testing standards introduced, such as AS/NZS 3845 in Australia, ensuring barrier systems were engineered and certified for performance.

Modern road crash barriers are precisely engineered, rigorously tested, and tailored for different road environments — from urban intersections to high-speed rural highways.

Barriers are now seen as part of a larger ecosystem of road safety — working in tandem with signage, lighting, and speed management to create safer journeys for all.

Road crash barriers have certainly come a long way since the beginning. At McIntosh Fencing, we’re proud to be part of this evolution — supplying and installing barrier systems that help save lives, every day.

Whether it’s a rural roadside or a high-speed motorway, we’re committed to designing and delivering barriers that suit the environment and meet the highest standards of safety.

Collisions between vehicles and wildlife pose a serious risk to both human and animal safety. Every year, thousands of accidents occur due to animals straying onto roads, resulting in injuries, fatalities, and costly vehicle damage. In Australia, where native wildlife such as kangaroos, wombats, and deer frequently wander onto highways and rural roads, finding ways to reduce these incidents is crucial.

One of the most effective solutions? Strategically designed road barriers. At McIntosh Fencing, we understand the importance of keeping both motorists and wildlife safe. The right barrier system can prevent animals from crossing dangerous roads, guide them toward safe passages, and reduce the risk of high-impact collisions.

Physical Deterrence: Keeping Animals Off the Road: Installing road barriers along highways and high-risk areas creates a physical boundary that discourages animals from crossing. Barriers such as steel guardrails and concrete walls act as deterrents, reducing the likelihood of sudden animal crossings, particularly in areas where high-speed traffic makes avoiding collisions difficult.

Guiding Wildlife to Safe Crossings: A well-designed road barrier system doesn’t just keep animals off the road—it also directs them toward designated wildlife crossings, such as underpasses or overpasses. These crossings provide a safe passageway for animals, ensuring they can move freely without entering the roadway. By integrating fences and barriers with these crossings, authorities can significantly reduce animal-related accidents.

Minimising Vehicle Damage and Driver Injuries: When an animal suddenly appears on the road, drivers often swerve to avoid impact, which can lead to loss of control, rollovers, or collisions with other vehicles. Road barriers can prevent cars from veering off the road or into oncoming traffic, reducing secondary accidents caused by sudden evasive maneuvers. Steel cable barriers and guardrails are particularly effective in containing vehicles while absorbing impact, keeping drivers safer in the event of a near-miss.

Protecting High-Risk Areas: Some roads are more prone to animal crossings than others. In rural areas, national parks, and forested highways, wildlife encounters are especially common. Installing animal-proof barriers in these locations, combined with warning signage and proper lighting, can significantly lower the chances of collisions.

• Steel Guardrails: Prevent vehicles from leaving the roadway while also acting as a deterrent for medium-sized animals.
• Concrete Barriers: Used in high-risk zones where large animal crossings are frequent, reducing the chances of vehicle-wildlife impact.
• Wire Rope Barriers: Absorb impact while allowing small animals to pass safely underneath.
• Wildlife Fencing: Installed alongside barriers to direct animals toward safe crossing points, reducing road access.

At McIntosh Fencing, we believe that road safety includes protecting both motorists and the environment. By implementing well-designed crash barriers and wildlife deterrents, we can help prevent dangerous animal collisions, minimise vehicle damage, and reduce injuries on the road.

If you’re looking for reliable road barrier solutions that enhance both driver and wildlife safety, get in touch with McIntosh Fencing today. Together, we can create safer roads for everyone—humans and animals alike.

Not all roads are the same, and neither are the barriers designed to keep them safe. From high-speed highways to winding rural roads, each environment requires a unique approach to crash barrier design to maximise safety and efficiency.

At McIntosh Fencing, we understand that a one-size-fits-all approach doesn’t work when it comes to road safety. That’s why we tailor our road crash barriers to suit the specific conditions of different road types, ensuring optimal protection where it’s needed most.

Highways experience fast-moving traffic, making it essential for barriers to provide high-impact resistance to prevent vehicles from crossing into oncoming lanes or veering off the road. The most common types of barriers used on highways include:

• W-Beam Guardrails: A strong, flexible steel barrier designed to absorb impact and redirect vehicles safely.
• Concrete Barriers: Used in high-risk areas such as medians or bridge edges, offering maximum durability and stopping power.
• Cable Barriers: A cost-effective option that absorbs kinetic energy and prevents severe crashes while minimising vehicle damage.

On highways, barriers must also be designed to prevent secondary collisions, ensuring that vehicles remain controlled after impact rather than rebounding into traffic.

Rural roads present unique challenges, such as narrow lanes, tight curves, and unpredictable wildlife crossings. Unlike highways, rural roads often lack wide shoulders, increasing the risk of vehicles running off the road. Effective crash barrier solutions for these roads include:

• Flexible Steel Barriers: Absorb impact while preventing vehicles from rolling down embankments or crashing into trees.
• Guardrails with Enhanced Reflectivity: Ensure visibility in low-light conditions, a common issue in rural settings.
• Wire Rope Safety Barriers: Useful for preventing head-on collisions on winding roads while reducing the severity of crashes.

By implementing these tailored safety solutions, rural road barriers help protect drivers from unexpected obstacles and dangerous roadside conditions.

 

Construction zones are constantly changing, making temporary and highly visible crash barriers essential. These areas pose risks such as sudden lane shifts, heavy equipment movement, and reduced space for traffic. Safety solutions include:

• Concrete Jersey Barriers: Provide a strong physical barrier to separate traffic from work areas.
• Water-Filled Barriers: A portable and effective option that enhances visibility and absorbs impact.
• Temporary Guardrails: Offer flexibility and quick installation while maintaining safety standards.

Ensuring proper barrier placement in construction zones prevents accidents, safeguards workers, and helps keep traffic moving smoothly despite ongoing roadwork.

Every road type presents different challenges, which is why crash barriers must be designed and installed with precision to meet the specific safety requirements of each environment. 

That’s why McIntosh Fencing specialises in designing and installing road crash barriers that are tailored to each unique road condition, ensuring safety for all road users

Severe weather events, particularly hailstorms, can be unpredictable and dangerous. Hail, with its sudden and intense nature, can cause extensive damage to vehicles, infrastructure, and even put lives at risk. One of the most crucial elements in ensuring the safety of road users during such unpredictable weather is the installation of high-quality road crash barriers. At McIntosh Fencing, we understand the importance of these barriers in protecting motorists, pedestrians, and cyclists during hazardous conditions, including hailstorms.

Hailstones can range in size from small pellets to golf ball-sized chunks of ice, and when they fall onto roads, they create several risks for drivers:

Reduced Visibility: Heavy hail can severely reduce visibility, making it difficult for drivers to see the road, other vehicles, or potential hazards.

Slippery Road Conditions: Hailstones quickly accumulate on roadways, making surfaces slippery and increasing the likelihood of vehicles losing control.

Damage to Vehicles: Hailstorms can cause significant damage to cars, trucks, and other vehicles, including cracked windshields, dented bodies, and damaged tires. This leads to an increased risk of accidents as drivers try to control their vehicles under adverse conditions.

Road crash barriers are often seen as a safety feature designed to prevent vehicles from veering off the road or colliding with oncoming traffic or fixed objects. However, their role in protecting motorists extends far beyond simple barriers—they serve as a crucial defense during hailstorms and other severe weather conditions. Here’s how:

Guiding Traffic and Preventing Collisions: During a hailstorm, it can be difficult for drivers to maintain control of their vehicles, particularly when visibility is poor, and road surfaces are slippery. Road crash barriers act as a physical guide, helping to direct vehicles safely along the road and reducing the chances of head-on collisions. In areas where lanes are narrow or curves are sharp, barriers ensure vehicles don’t drift into oncoming traffic or off the road, which is especially vital during low-visibility conditions caused by hail.

Preventing Vehicles from Skidding Off Roads: The icy surfaces left behind by hail can cause vehicles to lose traction, leading to dangerous skidding. Road crash barriers play an important role in preventing vehicles from veering off the road in such conditions. Their sturdy construction ensures that vehicles stay within their lanes, preventing dangerous rollovers or crashes into roadside ditches or embankments. This is particularly important on highways or stretches of road that are prone to severe weather.

When it comes to road safety, one of the most significant hazards is lane drifting which can lead to severe collisions, endangering the lives of motorists, cyclists, and pedestrians.

At McIntosh Fencing, we understand the importance of road crash barriers in preventing these potentially catastrophic events. Which is why in this blog post, we explore how our expertly designed road crash barriers play a crucial role in keeping vehicles in their lanes and enhancing overall road safety.

Understanding Lane Drifting

Lane drifting occurs when a vehicle unintentionally moves out of its designated lane. This can happen for various reasons, including driver distraction, fatigue, adverse weather conditions, or mechanical issues. The consequences of lane drifting can be dire, leading to head-on collisions, side-swipes, and crashes involving multiple vehicles.

The Role of Road Crash Barriers

Road crash barriers are essential for maintaining lane discipline and preventing accidents caused by lane drifting. Here’s how they contribute to road safety:

Providing Physical Boundaries: Road crash barriers serve as physical boundaries that keep vehicles within their lanes. By clearly delineating lane edges, these barriers prevent vehicles from unintentionally crossing into oncoming traffic or adjacent lanes. This is especially crucial on highways, curved roads, and areas with heavy traffic where the risk of drifting is higher.

Enhancing Driver Awareness: Barriers help enhance driver awareness by providing visual cues. Reflective materials and high-visibility designs make barriers easily noticeable, even in low-light or adverse weather conditions. These visual indicators remind drivers to stay within their lanes and maintain a safe distance from the barrier, reducing the likelihood of drifting.

Absorbing Impact: In the event of a collision, road crash barriers are designed to absorb and dissipate impact energy. This reduces the severity of crashes and minimises the risk of vehicles crossing into other lanes. Modern barriers incorporate advanced materials and engineering techniques to maximise their energy-absorbing capabilities, providing effective protection for both drivers and passengers.

Protecting Vulnerable Road Users: In addition to safeguarding motorists, road crash barriers also protect vulnerable road users such as cyclists and pedestrians. By creating clear separations between vehicle lanes and pedestrian or cycling paths, barriers help prevent accidents involving non-motorized road users. This is particularly important in urban areas and near schools or parks where pedestrian and cyclist traffic is high.
