Bellevue Pedestrian Bridge - Cable Stayed Pedestrian Bridge

Applications: Bridges

Location: Seattle, WA

Completion Date: 2005

Of all our recent bridge installations, none demonstrate the benefits of cable stayed construction quite like Bellevue Bridge.

The application of lightweight and spidery “tree like” canopy supports accentuate the minimalist cable stayed design, reflecting the approach taken by engineer and architect towards the optimization of structural and aesthetic performance.  The efficiency of the cables, the “lightness” and translucence of the canopy, and the slender lines of the masts and deck, all combine in a structure of unique elegance and function.

Ronstan Architectural was contracted to meet tight specifications in its supply of the 16 structural stainless steel mast cables. The cables comprised twelve 28mm diameter forestay cables and four 36mm diameter backstay cables.

The combination was engineered to provide essential stiffness of the bridge preventing vibration and movement. The cables were manufactured from 316 Stainless Steel 1x61 construction strand with Type 3 turnbuckles and fixed jaw fork fittings to facilitate adjustment and connection.
