Photos of American Bridges by Trucker Mike


I don't know the name of this classy-looking bridge, but it crosses one of the rivers that flows through Pittsburgh.	This is a good example of the sort of river traffic that uses the Mississippi River. The bridge in the background may be a railroad bridge heading into St. Louis. See the string of barges behind the riverboat?	This Red Arch bridge is located somewhere in Tennessee. I couldn't figure out how those arches could support both sides of the bridge, but a viewer wrote to explain the concept for this and the "A-frame" style. Strong cross-beams are supported in the middle by the arches or the A-frame and cables and the cross-beams support the roadways. The writer likened it to a person holding up a barbell with his hands in the middle of the bar and the weights at the ends.

Here is another style of 'hoop' bridge, again using cables inside the hoops to hold up the roadway. This bridge is somewhere in Alabama, probably on I.65.	This is a draw bridge in an industrial area along the shores of Lake Erie in Loraine, Ohio, spanning a canal and connecting the real mainland with the separated land on the other side. I was at a facility to pick up a load of minerals packed in 'super sacks', 4000 lb. bags on wooden pallets.	This is the Coronado Bridge in San Diego, CA. It is nearly 1.5 miles long and rises to 200 feet above the water at the center to allow passage of large ships under it. I have not seen it personally, but a visitor to this site suggested it be included since it is such an impressive structure.
