If there is a NOVA DVD.....I want a copy too. I like a copy of any DVD out there documenting the Arthur Ravenel bridge in S.Carolina. I happen to have a postcard of the old "Grace" cantilever in a scrapbook I made as a child devoted to my favorite subject...."bridges". I enjoy this website as well.
There was quite an interesting TV special on PBS's NOVA all about the construction of this bridge. It was two hours almost lost into detail going from routing the river flow and tower construction to when the roadway was finished. This apparantly sparked interest in some young minds on bridge construction. I don't know if a DVD of this can be purchaced anywhere or if this special will ever air again. I recommend watching it. They also showed the demolition of the old Alton Bridge at the end.
