One week after SDOT went public with some details of its emergency plan in case of West Seattle Bridge failure or imminent failure (WSB coverage here), it’s just published a close-up look at the new monitoring system. The graphic above is from the new SDOT Blog update, which also includes photos of some of the monitoring equipment.
Also explained – the monitoring is also key to the biggest decision yet to be made. Three main purposes are listed:*Keep us informed on how the bridge reacts to environmental changes, bridge stabilization measures, temporary shoring, and potential future repairs.*Give us a better indication of bridge distress that could warn of impending failure.
*Guide us to a decision about the technical feasibility of repair or replacement.SDOT says the system includes cameras, movement sensors, and crack monitors, noting.
