Novel Bridge Bird Exclusion Solution

Project Description

Innovative Bird Exclusion System Development

The Ironworkers Memorial Second Narrows Crossing (informally called the “Ironworkers Memorial Bridge” or “Second Narrows”) is a 6-lane bridge that spans the Burrard Inlet to connect North Vancouver to Vancouver and Burnaby.

Birds from common pigeons to protected species like cormorants have been nesting in the hollow spaces of the steel members that make up the frame of the Iron Workers Bridge. Aside from creating health hazards for maintenance staff, the bird droppings contain acids that eat away at the protective coating which is essential for the longevity of steel structures in climates such as the Pacific Northwest.

The project requires an innovative bird control solution which isn’t obviously available as an industry standard. Humane Solutions consulting services were procured to develop and propose a bird exclusion solution which would allow for excluding access to the structural holes in the steel members, while not compromising the paint or protective surfacing.

The Humane Solutions team went to the drawing board and came up with a proprietary magnetic, modular netting system which has since been named Mag-Nets®.
