Bailey Bridges, Inc.

“Apex” – The Apex style is characterized by a flat top chord and a curved bottom chord.  The architectural design of this arched truss makes this design an attractive option when aesthetics are important.  With its shallow truss depth at the center, the  Apex style is better suited for spans less than 100 feet.

“Guardian” – The Guardian style utilizes a full-through box truss design with top bracing for stability.  The deep truss and top bracing make this style particularly useful in highway and railroad overpasses where a security chain link fence is required.  The Guardian style can be used to clear span up to 200 feet.

“Cornerstone” – The Cornerstone style utilizes a modified bow truss with a curved top chord and a flat bottom chord.  The bridge deck can be cambered to match the top chord or flat to match the bottom chord.  The Cornerstone style is perfect for projects requiring a long span bridge with limited approach space.  The truss height varies to allow a low abutment backwall while still maintaining maximum truss depth at the center.  This style is popular because the cambered floor option allows a constant rail height for an unobstructed view over the top chord.  The Cornerstone style is perfect for longer spans up to 200 feet.

“Crossbow” – The Crossbow style incorporates a bowstring truss with a curved top chord to give a classic parabolic look.  The Crossbow style can be used in spans from 50 feet up to 200 feet.  The truss height at the center of the bridge is usually around 10% of the clear span.  With longer spans, the truss height may be reduced to 7% for easier shipping.

“Expedition” – The Expedition style is similar to the Trailblazer with parallel top and bottom chords.  This style incorporates two diagonals for an “X-braced” look.  The symmetry of this style makes it a popular choice for multiple span bridges.  Similar to the Trailblazer, the Expedition can have vertical or sloped ends and can also span over 150 feet.

“Trailblazer” – The Trailblazer style is a familiar Pratt truss design with parallel top and bottom chords.  The ends of this style can either be vertical or sloped if desired.  By increasing the truss height and raising the floor up in the truss to form an “H-section”, the Trailblazer style can span over 150 feet.
