Elevating utilitarian infrastructure to a thoughtfully designed community asset, the Grand Avenue Park Bridge highlights the value of rethinking public realm design. The bridge transforms the Everett waterfront, establishing a new connection between the historical Grand Avenue Park and the city’s developing waterfront district. At the bridge’s recent opening, Mayor Cassie Franklin commented, “It is a beautiful bridge, it is a utility project, and it is going to be part of our city for generations to come. It is a gorgeous new asset.”
大道公園大橋將功利主義基礎設施提升為經過精心設計的社區資產，彰顯了重新思考公共領域設計的價值。 這座橋改變了埃弗里特（Everett）的濱水區，在歷史悠久的大大道公園（Grand Avenue Park）和城市發展中的濱水區之間建立了新的連接。 市長卡西·富蘭克林（Cassie Franklin）在這座橋的近期開放中評論說：“這是一座美麗的橋，它是一個水電工程，它將成為我們城市的子孫後代。 這是一種了不起的新資產。”
The new bridge solves a complicated sequence of grade-changes and utility needs in an unlikely new form that weaves pedestrian ramps and stairs above, around, and inside a sloping truss, presenting an inviting new crossing from Grand Avenue Park to the waterfront district. Across its 257-foot span, the bridge carries major utilities while navigating a network of existing electrical lines, a five-lane highway, and the BNSF train tracks at the base of an 80-foot-tall steep slope, all while preserving views from the park above. In part, the amazing views are preserved by having a unique entrance onto the top of the bridge such that most of the bridge structure is below Grand Avenue Park.
這座新橋以一種不太可能的新形式解決了複雜的坡度變化和公用事業需求，這種新形式在傾斜的桁架上方，周圍和內部編織了人行道坡道和樓梯，是從大大道公園到濱水區的引人入勝的新交叉路口。 該橋橫跨257英尺，橫跨主要的公用設施，同時可導航現有的電力網絡，五車道的高速公路以及位於80英尺高的陡坡底部的BNSF火車軌道，同時還能保留來自 上面的公園。 通過在橋頂上有一個獨特的入口，使大部分橋樑結構都在大大道公園下面，可以保留部分令人驚嘆的美景。
The design is 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.
該設計是實用且經濟的。 桁架形式直接響應其程序需求，同時回想起西北太平洋地區發現的傳統鐵路桁架的形式和特徵。 結構元件由耐候鋼（一種鋼的原始形式）構造而成，該鋼使用銹形成保護層，從而提供耐腐蝕性並隨著時間的推移提高橋樑的可維護性。 環繞在桁架中並穿過桁架，閃閃發光的花邊護欄也充當了橋樑的實際尋路系統，與生鏽的桁架的銀色鋁面板形成了鮮明的對比。
The guardrail features a bespoke perforation that is inspired by the forms of the surrounding natural environment. The varied density of perforations was designed to enhance the reflectivity of artificial lighting, improving the performance of the integrated linear lights at the top of the rail while minimizing glare and light pollution. Each aluminum panel is unique, responding to the geometry of the bridge, views beyond, and varying guardrail requirements.
護欄具有定制的穿孔，其靈感來自周圍自然環境的形式。 設計不同的穿孔密度，以增強人造照明的反射率，改善軌道頂部集成線性照明的性能，同時最大程度地減少眩光和光污染。 每個鋁板都是獨特的，以適應橋樑的幾何形狀，視野之外以及護欄的不同要求。
Geometry for the 400 aluminum panels was generated through a computer script, automating the layout, numbering, and cut file production. A separate file for each panel was provided to a fabricator for use with their computer numerically controlled (CNC) Waterjet. LMN Principal Scott Crawford says that “LMN’s experimentation with our own CNC machine to fabricate full-scale mockups was essential for refining the scale of the pattern, adjusting the amount of area for the light reflection, and testing the digital cut files. This close collaboration allowed for a solution that is finely tuned to its context.”
通過計算機腳本生成了400塊鋁板的幾何圖形，可自動進行佈局，編號和切割文件的製作。 將每個面板的單獨文件提供給製造商，以供其計算機數控（CNC）Waterjet使用。 LMN的負責人Scott Crawford說：“ LMN用我們自己的CNC機器進行試驗以製造完整尺寸的模型對於優化圖案的比例，調整光反射的面積以及測試數字切割文件至關重要。 這種緊密的協作使解決方案可以根據上下文進行微調。”
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.
大型桁架元素和小規模穿孔的覆蓋物可為人行道上的視覺，光線和陰影帶來動態體驗。 一座高大的混凝土電梯和公用設施核心作為西部的基台，其混凝土牆以相同的穿孔方式爆破，並包裹在通往人行水旁海濱長廊的樓梯中。
The bridge’s iconic presence is rooted in the unexpected formal juxtaposition of muscular and delicate, rustic and refined, symmetrical and asymmetrical, inside and out. Since its completion in late August, the Grand Avenue Park Bridge has become a popular destination, enhancing the pedestrian life of the Northwest neighborhood and the growing mixed-use waterfront district. By embracing a creative pragmatic approach, the design addresses both functional and aesthetic demands, weaving urban infrastructure into the life of the city and becoming a catalyst for continued community revitalization.
這座橋的標誌性存在源於內外由肌肉和精緻，質樸和精緻，對稱和不對稱的出乎意料的正式並置。 自8月下旬竣工以來，大大道公園橋已成為一個受歡迎的目的地，從而改善了西北社區和日益發展的多功能濱水區的步行生活。 通過採用創新的務實方法，設計既滿足功能性要求又滿足審美要求，將城市基礎設施融入城市生活，並成為社區持續振興的催化劑。
