Welcome to the Sahale world of swinging bridges, trails, and breathtaking landscapes! This web site contains more than 1,000 images of Sahale’s work designing and building trails and trail and vehicle bridges.

Between 1992 and 2010, Sahale LLC specialized in the design, engineering, construction and repair of trails, trail bridges, and long-span cable bridges. Sahale LLC ceased operations in 2010, after the death of its founder and owner, Carroll Vogel. Learn More

Sahale LLC bridges and trails were designed to accommodate every possible recreational user, including bikers, equestrians, skiers, and cyclists. Sahale’s largest pedestrian bridges were suitable for light vehicle traffic, including golf carts, snow cats, pickup trucks, and sport utility vehicles. Sahale heavy vehicle bridges met current AASHTO heavy vehicle load requirements for buses and multiple axle trucks, including semi-tractor trailers and concrete trucks. When necessary, trails and bridges built by Sahale also met ADA accessibility standards.

You may have already crossed a Sahale bridge or used a Sahale trail. Sahale handiwork can be found across the country, whether you are hiking the Appalachian Trail, skiing the groomed ski trails of the Methow Valley in Washington State, backpacking the forest trails of the Oregon Coast, or trail riding the rugged backcountry of the High Sierra; Sahale was there to design and build trails and bridges that rest easily on the natural landscape, as aesthetically pleasing as they are functional.

Sahale bridges were designed to be simple and modular in concept. Every structure contained unique design elements in galvanized or weathering steel, galvanized or stainless cable, and other features. Sahale bridges could vault hundreds of feet further than heavy, rigid bridges, and were especially ideal for remote, rugged sites accessible only by trail or air. These structures were routinely designed, fabricated, and installed by Sahale personnel. Sahale’s philosophy was:

  • To design and build graceful and aesthetically pleasing bridges that could be erected anywhere, even in the most remote locations.
  • To employ construction methods that resulted in minimal environmental disturbance, and were appropriate for Wilderness or National Park settings.
  • To rely on time-tested rigging and steel erection methods and practices.
Sahale was dedicated to the concept that integration of planning, design, engineering, and construction processes produced the most cost-effective, efficient, environmentally sensitive, and enduring end products. In the context of this design/build philosophy, Sahale always sought projects that demanded exceptional technical expertise, craftsmanship, sensitivity to the natural environment, and adherence to the highest principles of stewardship and conservation.
