A Wireless Sensor Network (WSN) for Structural Health Monitoring (SHM) is designed, implemented, deployed and tested on the Golden Gate Bridge (GGB). Ambient structural vibrations are reliably measured at a low cost and without interfering with the operation of the bridge. Requirements that SHM imposes on WSN are identified and new solutions to meet these requirements are proposed and implemented. In the GGB deployment, 59 nodes are distributed over the span and the tower, collecting ambient vibrations in two directions synchronously at 1KHz rate, with less than 10us jitter, and with an accuracy of 30uG. The sampled data is collected reliably over a 44 hop network, with a bandwidth of 461B/s at the 44th hop. The collected data agrees with theoretical models and previous studies of the bridge. The deployment is the largest WSN for SHM.
