LMN architects curates luminous bridge with delicate perforations in everett, washington

seattle-based studio LMN architects celebrates its newly completed ‘grand avenue park bridge’ in everett, washington. the 257-foot-long bridge creates a new viewing platform and civic space with an inventive, accessible pathway. the unique structural system comprises an asymmetrical weathering steel truss spanning from the hillside to a vertical concrete tower, creating a sequence of new civic spaces and connecting grand avenue park with everett’s growing waterfront district. together with its posture, the bridge is characterized by an expressive guardrail featuring a bespoke perforation inspired by the forms of the surrounding natural environment. the varied density of perforations is designed to enhance the reflectivity of the artificial lighting, while minimizing glare and light pollution.

everett’s grand avenue park bridge marks the first pedestrian and utility bridge designed by LMN architects in partnership with KPFF consulting engineers. both functional and design-minded, the project stands as a composition of concrete and steel, and of nature and digital design technology. the overlay of large-scale truss elements and small-scale perforations creates a dynamic experience of view, light and shadow along the walking path. a tall concrete elevator and utility core serve as the western abutment, its concrete walls blasted with the same perforation pattern and wrapped in a staircase that leads to the pedestrian-level waterfront promenade.

LMN architects designs its grand avenue park bridge in everett to be both pragmatic and economical. the truss form responds directly to its programmatic needs while recalling the form and character of traditional railroad trusses found across the pacific northwest. the structural elements are constructed of weathering steel, a raw form of steel, which uses rust to form a protective layer, providing corrosion resistance and enhancing the bridge’s maintainability over time. wrapping around and running through the truss, a shining, lacey guardrail also serves as the bridge’s de-facto wayfinding system, contrasting with the raw character of the rusted truss with its silvery aluminum panels.
