The number of Canadian shoppers plummeted in parts of western Washington after the collapse of the Skagit River bridge in May.
Border policy researchers at Western Washington University have been observing the number of Canadian license plates at businesses along the I-5 corridor.
Their study shows the number of shoppers dropped 51-percent from March at eight businesses south of Burlington.
The research began before the Skagit bridge on May 23 collapse to get a better understanding of Canadian shopping activity in the region.
Officials at the Wal-Mart and Costco stores in Burlington say they saw a decrease of more than 40-percent.
