Blue Water Bridge

This picture was taken at Blue Water Bridge Park along the St Clair River in Sarnia, Ontario.  The Blue Water Bridge is a twin-span international bridge across the St Clair River that links Port Huron, Michigan, USA and Sarnia, Ontario, Canada.  The twin spans were built at different times and with different structural systems, the original cantilever truss bridge (background) was completed in 1938 and the second span, a continuous tied-arch bridge (foreground) was completed in 1997.  I can definitely figure out why the name of the bridge, the water in the St Clair River has the most beautiful deep blue color I have ever seen in a river.
