LMN architects utilizes weathered steel trusses to build pedestrian bridge in washington

in everett washington, construction has began on a new 282-foot-long (86 meter) pedestrian bridge designed by LMN architects. the project is set to be completed in early 2020 and will provide a vital link from the city to the burgeoning waterfront district. built around a sloped pathway that removes the need for elevators, the massive intervention will connect the lower downtown area with a 75-ft-high (23m) hillside.

with this project LMN architects strives to create a contemporary, pragmatic and transformative piece of infrastructure within the public realm. not only will the design bridge the uplands grand avenue park with downtown everett, it will also bring pedestrians and utilities safely over a steep slope, a busy commercial railway and a state highway. the project will fulfill a decades-long goal for a convenient, non-motorized passage to the waterfront, which features a growing 66-acre mixed-use development, the everett farmer’s market, and the largest public marina on the west coast.

‘it has been thrilling to work with the city of everett and our partners KPFF engineers in reimagining the civic potential of this important piece of new infrastructure,’ says LMN partner stephen van dyck. ‘this ambitious design is a result of visionary leadership at the city and beyond that is committed to elevating the experience of the city while serving its communities and planning for its future growth.’

by incorporating a sloped truss, the design team eliminated the need for an uphill elevator, therefore preserving the waterfront view and saving significant costs. built using weathered steel, the truss recalls the image of a railroad overpass and integrates a sequence of pathways with the aim of giving pedestrians an experience through a ‘whimsical play of space, light, and structure.’

‘increasing the accessibility of our public spaces is one of the most important investments we can make in building sustainable infrastructure,’ explains van dyck. ‘for this project, accessibility and safety were the primary driving forces in the design, from the integrated railing system to the iconic form of the bridge itself.’

a ribbon of aluminum panels accompanies pedestrians along the pathway, serving as safety rails, lighting reflectors, and a unique wayfinding visual element. the panels also feature a waterjet-cut perforation pattern that opens views at eye level. by embracing a creative, yet pragmatic approach, LMN’s design intends to address both functional and aesthetic demands, weaving urban infrastructure into the city life and becoming a catalyst for continued community revitalization.
