Intelligent monitoring system on West Seattle High-Rise Bridge nearly operational

For over a month now, we’ve been installing new monitoring instrumentation consisting of additional movement sensors, crack monitors, and monitoring cameras throughout the bridge. Our goal is to improve our understanding and tracking of the health of the West Seattle High-Rise Bridge with greater precision and with real time data.

While installation has been underway, we’ve continued performing regular bridge inspections.

These inspections revealed that while crack growth slowed when traffic was removed from the bridge, it hasn’t stopped the cracking. The new monitoring system is critical to recording this data.
