| This is an A-frame style cable suspension bridge on US Route 22 at Weirton, WV, crossing the Ohio River. | Early construction and later progress on the new bridges carrying I.495 across the Potomac River south of Washington, DC. | I forget where I saw this combination Arch/Cable-stayed bridge, but isn't it pretty? |

| This is the historic 16th Street Bridge crossing the Allegheny River in south-east Pittsburgh, PA. | 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 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. | 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. |
