If the GGB was to be built today, dense instrumentation of wireless sensors to monitor the bridge and its loads would be possible. These devices are low-cost and growing increasingly ubiquitous in a variety of societal applications. For example, the most recent long-span bridge to be built in California, the New Carquinez Bridge in Vallejo, CA, now has a dense wireless sensor network installed in it by the University of Michigan with nearly 100 sensor channels ranging from measurements of acceleration and strains to wind speeds and temperature. The benefit of deploying wireless sensors on the GGB would enormous including the ability to identify how traffic loads the bridge, identify instances of bridge deterioration, and could be an enabling element of a post-earthquake inspection system that ensures bridge safety immediately following a large quake. In addition, data collected by a bridge monitoring system would go a long way toward validating current design strategies for such bridges leading to safer bridges that are lower cost to design, build and maintain over their lifecycle.
