The Redmond Technology Station Pedestrian Bridge exemplifies the power of innovative design, construction, and collaboration between public and private entities. Benefitting clients, communities and the construction industry alike, it provides a stunning, functional and sustainable solution that raises the bar for public infrastructure projects.

Great efforts were made to create both beautiful and functional spaces on the bridge. Separated lanes allow cyclists and commuters to travel quickly, while meandering paths invite users to slow down and enjoy the crossing.

With the bridge footprint on the ground limited, the structure is supported by drilled shafts, with a combination of post-tensioned WF102G girders and trapezoidal tub girders forming the superstructure. To integrate the structural elements with the architectural design, Kiewit utilized Building Information Modeling (BIM) for precise planning, minimizing waste, improving efficiency and visualizing potential challenges before construction began.

After thorough mock-ups, ideal finishes were selected for the architectural concrete, resulting in flawlessly executed placements that create a visually appealing mix of finishes. Numerous pre-cast components were meticulously set and aligned throughout. The team ensured that all colors and patterns were well-coordinated, contributing to the bridge’s cohesive and polished appearance, connecting the design languages of Microsoft’s new East Campus, the existing West Campus, and Sound Transit’s Redmond Technology light rail station. The team excelled in executing this complex design with exceptional quality and craftsmanship.

To protect users from the elements, the bridge is covered by an interconnected white tensile fabric canopy supported by architecturally exposed structural steel. The membrane panels alternate between push-up steel masts and pull-down steel elements, which are integral to the rain gardens on the bridge. At night, the bridge is illuminated by light reflected off the underside of the canopy membrane.

This bridge sets new industry benchmarks, demonstrating that infrastructure can be both functional and beautiful. By prioritizing user experience alongside utility, it inspires future projects to embrace innovative design and construction techniques. Its environmentally responsible features, such as native plantings and improved pedestrian and cycling pathways, highlight the potential for public infrastructure to support sustainability.

Kiewit’s safety culture on the Redmond Technology Station (RTS) Pedestrian Bridge Project centered around the company’s Craft Voice in Safety (CVIS) Program. Driven by craft engagement, Kiewit employees played a crucial role as the first line of defense by proactively managing risks, identifying hazards and promoting safety. The CVIS team, composed of craft workers from various trades and subcontractors, determined any additional training beyond what was required by industry standards. The CVIS team met directly with project management at least weekly to promote open communication.

Kiewit completed the project on time and within budget, meeting the client’s expectations for both schedule and financial constraints. The early use of value engineering allowed for cost savings without sacrificing quality, which the client greatly appreciated.

Additionally, throughout the project, Kiewit maintained constant communication with the client, providing regular updates on progress and promptly addressing any concerns. The client expressed satisfaction with the transparency and responsiveness of Kiewit’s team, highlighting these aspects in post-project evaluations.
