DECK:  Native or treated timber, or engineered concrete panel

RAILING:  Treated timber, cable, or steel fence


Sahale is an innovative leader in the design, engineering and fabrication of engineered steel, rigid span trail bridges.  These stringer style bridges incorporate a rigid steel framework with a variety of deck and railing options. The steel frame work is manufactured by Sahale and comes in kit form, ready to assemble.  Most bridges are manufactured using self-weathering steel, thus providing an environmentally neutal color for the bridge and eliminating the need for painting, for the life of the structure.  Sahale stringer bridges are engineered to meet AASHTO design standards for pedestrian and light vehicle bridges.

Many Sahale clients have come to prefer a trail bridge deck system consisting of engineered concrete panels.  These panels provide a durable, long wearing, non-skid, maintenance free surface for the life of the bridge and are manufactured by Sahale to sustain common impact and live loads defined by AASHTO for pedestrian and light vehicle br100' span steel stringer bridge with split cedar deck and railing.idges.  More traditional native and treated timber decks are also available, upon client request.

50' span steel bridge with timber deck, railing and fascia.Rigid steel bridges by Sahale can be provided with a timber fascia for disguising the steel girders, per client request.  The fascia is easily fitted to the bridge during assembly and is designed to appear continuous, without visible vertical joints, simulating a timber stringer.  Assembly of a Sahale rigid bridge is a simple matter of bolting together marked components that were test fit during the manufacturing process.  There is no drilling, welding, or cutting of steel required.  

Sahale bridges are commonly assembled by volunteer and youth crews, under the supervision of a trained crew leader.  Taylor Creek Bridge (above) was a project of the King County World Conservation Corps.  Sahale works with the client to design a bridge around site limitations such as limited access, equipment restrictions, and environmental factors, and provides the necessary technical guidance in how to solve logistical and construction dilemmas associated with building at remote bridge sites.
