Laminated timber isn’t just for buildings anymore. It’s making a big impact in bridge construction, too. This strong material is helping architects and design engineers build bridges that last longer, look better, and are easier on the environment. With new tools and design methods, it’s now a smart option for everything from footbridges to vehicle crossings. Here’s how laminated timber is changing the way bridges get built.
What Is Laminated Timber?
A type of engineered wood, laminated timber is made by bonding layers of wood together with strong adhesives. These layers, also known as “laminates,” are stacked in a way that makes the final product stronger and more durable than regular wood. The layers are usually placed with the grain running in different directions to improve strength and stability.
Because of how it’s made, laminated timber can handle larger loads and resist bending better than solid wood. This makes it an excellent choice for large commercial projects, like beams, columns, and bridges, where reliability is important.
Why Laminated Timber Works for Bridges
Laminated timber is excellent for bridges. It can handle heavy weight and constant traffic without losing its integrity. Unlike solid wood, laminated timber can flex under pressure without cracking, making it more durable over time. It also stands up well to the elements—wind, water, and weather—ensuring the bridge remains strong and safe through all types of conditions. This combination of flexibility and resistance to the environment makes it a top choice for long-lasting bridges.
Sustainability and Speed
Laminated timber is made from renewable materials, so it’s a greener choice for your next project. It has a much lower carbon footprint compared to steel or concrete. That means you can build strong structures while reducing environmental impact. It also saves time on the job. Laminated timber components are made off-site and go up fast once delivered. That leads to fewer weather delays and a quicker path to completion.
So, you get a strong, reliable structure—without slowing down your timeline or increasing your carbon load.
Real-World Use and Success Stories
Laminated timber bridges are proving their value in real-world applications across the globe. For instance, York Bridge Concepts blends bridges with their surroundings while offering durability. Their projects showcase how laminated timber can be used effectively in modern infrastructure. For example, the Hendrick Auto Vehicular Timber Bridge in Charleston, SC.
Another notable example is the Placer River Trail Bridge in Alaska. It holds the distinction of being the longest clear-span glulam timber truss bridge in North America. This bridge demonstrates the strength and longevity of laminated timber in challenging environments.
These projects highlight the benefits, including low maintenance requirements and long service life. Their success stories serve as a testament to the material’s reliability in various settings.
Is Laminated Timber Right for Your Project?
Laminated timber can be a great choice, but it depends on a few key things. Start by thinking about where the bridge will go. Is it in a park, along a hiking trail, or on a rural road? These settings are perfect for laminated timber, blending in with nature and handling light to medium traffic with ease.
Next, look at how the bridge will be used. Will it carry people, bikes, golf carts, or vehicles? Laminated timber can handle all of that, but the span size and load type will affect how the bridge is designed.
Good design is what really makes laminated timber work. A solid plan helps it resist weather, carry heavy loads, and last a long time with minimal upkeep. With the right mass timber construction experts, laminated timber delivers strength, style, and sustainability—all at once.
A New Path Forward in Bridge Building
Laminated timber brings a lot to the table. It’s strong enough to handle heavy traffic but flexible enough to move without cracking. It also looks great, whether the bridge is in the middle of a city or deep in a park. On top of that, laminated timber is better for the environment than steel or concrete and takes less time to install.
This mix of strength, speed, and sustainability is why more projects are turning to laminated timber. From walking trails to rural roads, it’s helping build bridges that last while keeping things efficient and eco-friendly.
