  Maxwell Bridge- Napa, CA:

 Lighting Concepts for Maxwell Bridge Design Lighting:
Light fixtures will be attached every 60 meters on the outside of the bridge (using metal wings that are easily removable for servicing). The lamp poles, while illuminating the sidewalk and street surface, will also be integrated with the barrier/curb designs, so that they appear to grow out of the bridge.

Piers:
An elongated octagonal column shape is used to reinforce the upper pier elements. The upper pier shape is flush with the side of the viaduct. This unifies the concrete structure and its sloped elements, reinforcing the overall lightness of the massing.

 Barriers for Maxwell Bridge Design Barrier:
The shaped side of the bridge viaduct was used on the barrier exterior. These elements provided continuity across the entire bridge span. The open barrier enhanced the visibility for the user (the openings allow light to flow over the road surface). Mirrored on both sides of the

pathway, the barrier composition creates a visual symmetry and rhythm, which is further enhanced by the placement of the lamp poles.
