Loading & Usage Diagrams Resources Page

At York Bridge Concepts, we understand the critical importance of safety, efficiency, and functionality in bridge design and construction. Our Loading & Usage Diagrams Resource Page is dedicated to providing engineers, architects, and project stakeholders with comprehensive resources and guidance on understanding and implementing loading and usage considerations in bridge projects.

"I didn't know a wooden bridge could do that!"

Most people don’t know about road ratings or loading capacities - we get that. Lots of people underestimate timber bridges - we know that. So to save you a challenging web search, time, and maybe even some money, we made this webinar for you! This session will outline both vehicular and pedestrian uses that timber bridges are great for AND give you access to guideline resources on how you can determine what capacity might be necessary for your next project. From accommodating highway standards to some supersized requests for powerline companies, mining facilities, and construction equipment, we’ve got projects that’ll make you say, “I didn’t know a timber bridge could do THAT.”

Usage Studies

Understanding how a bridge will be used is essential for its design and functionality. We conduct usage studies to analyze traffic flow, pedestrian behavior, loading patterns, and other relevant factors. By gaining insights into user behavior, we can optimize the design and layout of the bridge to enhance safety, accessibility, and user experience.
