“We chose Cambridge metal mesh so lettering and design could be etched into the material. I also wanted the bridge to be as 'open' as possible to offer views of the bay and to eliminate dark or hidden areas so everyone felt safe."

Application

The City of Martinez erected a 110-foot pedestrian bridge over the Northern Pacific Railroad tracks in 2019 to connect the town's Amtrak station and intermodal facility with an auxiliary parking area located adjacent to Martinez Regional Shoreline Park. The station, built in 2001, was originally designed with a second floor entryway that would connect to a foot bridge. But the span was not built until 18 years later when demand for commuter train and bus parking grew. Architects sought an open solution for enclosing the bridge that preserved views and eliminated dark or hidden areas so pedestrians felt safe. 

Function

Panels encompassing more than 2,400 feet of Cambridge's Mid-Balance stainless steel mesh with 50 percent open area were used to enclose the bridge. The mesh was affixed to the pre-fabricated structure with Cambridge's Eclipse attachment system. In partnership with Metal-Arch, Cambridge etched the "Martinez" name and bay grass designs in the stainless steel. Sandblasting the raw stainless, created a texturized, dull, matte finish to form the letters and grasses. At night, the bridge is accented by a wave-like light tube connected to the metal fabric. Mesh was also used for handrail infills on the circular platforms at the elevator landings on each end of the bridge.

Benefit

The openness of the mesh allows bridge pedestrians to "see out" with views of the Carquinez Strait and the Benica-Martinez Bridge to the northeast as well as Mt. Diablo and the Diablo Valley to the southeast. The ability to "see in" provides an added safety measure for pedestrians traversing the walkway.
