A Legacy as Strong as the Bridges We Build.
In 1985, James York changed the landscape of American bridge building - literally. As the founder of the largest nationwide timber bridge company, he pioneered the timber bridge industry in the U.S. and beyond, innovating, designing, and forging thousands of structures across four continents. After 38 years of leading the field, he stepped away.
But legacy has a way of calling you back.
Bridge Solutions
Design & Engineering
From concept to final plans, we design each bridge with precision and creativity. Using 3D terrain modeling, we tailor every detail to site conditions, choosing materials for carbon savings, durability, and a natural fit to the landscape.
Onsite Construction
We build your bridge components to exact specifications on your site using top-down methods when applicable, which protect sensitive terrain. From abutments to decking, every piece is assembled by skilled craftsmen, ensuring a precise fit and a lasting structure.
Permitting Support
MBC fully supports the client through the permitting process by providing sealed bridge drawings, answering RFI’s, and meeting with permitting agencies as needed, in conjunction with the client.
Maintenance & Inspections
The same team that builds your bridge is available to maintain it. We offer scheduled inspections, treatments, and repairs that extend lifespan, preserve aesthetics, and keep your bridge safe and strong for decades.
Strength You Can Stand On
At Montana Bridge Company, sustainability isn’t an afterthought; it’s built into every timber beam and bolt. Our bridges lock away carbon for decades, using responsibly sourced timber from regional mills to strengthen both local economies and the planet. By working from the top down, we avoid heavy equipment on fragile ground, protecting habitats, waterways, and soil health. Every design is tailored to its environment, with advanced treatments and recycled or reclaimed materials when available, ensuring your bridge weathers the decades beautifully. The result? Structures that blend naturally into the landscape, carry a lighter footprint, and stand as lasting connections between people and place.
