Cochrane-Africatown Bridge
Posted July 2, 2010, by Calvin Sneed (us43137415 [at] yahoo [dot] com)

Oh, not at all.. this is one of the most securely stable cable-stayed suspensions in the eastern United States. My experience is with the cable-stayed's on the Ohio River.. this one is much longer, and is built to handle much more weight than those. Because of the hazardous cargo requirements, this one is one of the strongest east of the Mississippi. Examine it close as I did. The supports are very rigid, and the deck is very stiff to prohibit deforming of the steel supports, under heavy weight and high winds.

Truly a spectacular architectural marvel! Could not wait to see it!
