Description 

"The bridge consists of three continuous spans of 150,475 and 120 feet of a 12-foot deep (constant depth), trapezoidal box girder composite with a 6-inch concrete deck. The box girder is fabricated from weathering steel to achieve a simple rustic look that is consistent with the surrounding environment and other structures on the connecting trails. Uplift of the short end spans was addressed by placing a hold-down at the west abutment and filling the first 95 feet of the east end span.

The pedestrian/bicyclist railing is composed of continuous horizontal members and vertical pickets painted a deep brown color to complement the weathering steel box girder. Portals, steel towers and suspension cables were detailed to enhance the visual impact of the bridge and to provide the pedestrians and bicyclists with a sense of security and comfort as they crossed. An adjustable system of weights was utilized to keep the suspender cables taut and vertical while allowing for thermal movements and deflection of superstructure. Photo of horses on the trail

The superstructure is supported by concrete abutments and hollow shaft piers. The east abutment is a stub type with flared wing walls founded on rock bluff, while the west one is a highwall abutment with laid-back parallel wing walls supported by micropiles and the first 46 feet of hollow shaft was filled with concrete to resist impact from floating debris during high water.

The west pier is supported by steel H-piles, while the east entrance portal is founded on drilled shafts. The exposes surfaces of the entrance portals, abutments, wing walls, piers, and edges of deck were all coated with a solid color sealant to provide a uniform appearance and enhance their visual effect.

The superstructure and aesthetic suspension system were extensively modeled and analyzed for wind and pedestrian-induced vibration and flutter. The results indicated that internal tuned mass damper should be provided to preclude any potential for vibrations or pedestrian discomfort that has come to light recently in several high-profile structures after they were opened to the public. In this case, five small dampers were installed— three for vertical and two for horizontal motion." - AmericanTrails.org
