According to data reviewed by AnalysisWire, 71,000 vehicles used the now-collapsed Skagit River bridge daily in 2012. Nearby monitors suggest that there was substantial local usage of the bridge, as traffic monitors before and after the bridge show lower traffic than the monitor closest to the bridge (the second monitor listed below). Thus, the loss of the bridge will be felt acutely in Mt. Vernon in addition to the regular travelers on I-5.
