Clark Bridge - Alton, Illinois

Thank goodness for bridges like the Clark Bridge - innovative, statuesque, and modern.  Something the locals can be proud of.  And a fantastic subject for your devoted amateur blogger/photographer.

The Clark Bridge (of Lewis & Clark fame) is US-67's span across the Mississippi River. It is not a suspension bridge; the Clark Bridge is known as a "cable-stayed bridge", made unique by the "saddle" design atop the two 250 ft. towers (a design no longer used due to a serious 'flaw').

The Clark Bridge, locally known as the "Superbridge," due in part to a NOVA television special documenting the construction of the bridge. The bridge connects Saint Charles County, Missouri to the city of Alton, Illinois - a town of about 30,000 residents located on the northern edges of the greater Saint Louis metropolitan area. Alton is also known for its long history as a 'Mark Twain' style river town - and a long and involved haunted history as well!

Note the "saddle" design - the cables wrap over the top of the towers. The Clark Bridge uses more than 160 miles of cable wrapped with four acres of yellow plastic piping. This unique design is known as a "cable-stayed bridge."
