These pedestrian bridges mark the south entry to the City of Shoreline. The gateway bridge over Aurora features a celebratory arch with trolley-inspired, windowed blue glass. The 155th Street bridge marks the historic Interurban Trolley Line and includes mesh screening as well as the blue glass window patterns. Together they form a vital community link in a regional trail system. Other elements inspired by the rail line and community history, and collaborative envisioned and implemented by the artist and design team, include LED light sculptures marking the bridge ends, rail-shore ramp patterning with sea creatures and wave forms, a reference to former orchards in the park-like area connecting the bridges and water harvesting and swales in the landscape amenities.
