BRIDGES, PEDESTRIAN

Lincoln Square Bellevue Way Bridge, Bellevue, Washington


This glass and steel, cable-supported skybridge provides direct access from Bellevue Square Mall to the Lincoln Square mixed-use facility. The bridge has a trapezoidal shape to provide protection from strong winds and is skewed across the 107’ span. Because of the bridge’s high visibility, the owner specifically requested a design that was thoroughly modern, transparent, and comfortable to its users, without the vibration or movement common to most cable-stayed structures.

Office Campus Bridges, Redmond, Washington

These two 120' long x 12' wide steel walkbridges connect three office towers on a major software manufacturer’s campus. Each bridge consists of three 24" diameter U-shaped bents supporting 20" x 8" steel tube stringers. Because the supports for each bridge spring from three different segments, they were designed to accommodate the relative movement of these segments.
