a couple of bridges
the first is the williamsburg bridge in ny (east river bridge from brooklyn) under construction in 1902. just thought it was a very interesting pic. (from the second: circa 1905. "aerial bridge. duluth, minnesota." suspended car transfer over the duluth ship canal. the gondola could carry 60 tons of cargo across the 300-foot channel with minimal obstruction of the shipping lane. after modification for service as a vertical lift, the span became known as the aerial lift bridge. great pictures! thanks! cool!! hg this page: nice link, mike. i got curious. it's a curse. mike halloran pembroke pines, fl, usa amazing structures built by men of steel. the aerial bridge looks a lot like transporter bridges (mostly in europe), first built in 1893. |
