Overview
About This Project
Replacing a 1960s drawbridge that had become a critical bottleneck, Harbor Crossing is the longest cable-stayed bridge in the Pacific Northwest — and the first in the region to incorporate a separated multi-use active transport path.

The Challenge
What We Were Up Against
Working above a navigable waterway with traffic restrictions and seasonal salmon migration windows compressed available in-water work to specific calendar periods.
Our Solution
How We Delivered
A floating falsework system enabled simultaneous balanced cantilever construction from both towers, completing all below-waterline work six weeks ahead of programme.
