These photos were also taken while on the boat tour in Charleston, SC around 1969-70. The lettering is handcut. The journaling reads:
"These are the “Cooper River Bridges”, which crossed the Cooper River and Town Creek, connecting Charleston, SC to Mt. Pleasant, SC. The Grace Memorial Bridge (nearest in right-hand photo) opened in 1929. Prior to this, the only way to cross was by ferry or private boat. At the time of construction, this was the largest bridge in the world of its kind (cantilever truss), spanning 2.71 miles in length and standing 15 feet higher than the Brooklyn Bridge. It consisted of two narrow lanes (each 10 ft. wide with no curb or median). I can remember crossing this bridge numerous times and it was quite nerve-wracking, even at my young age. The Pearman Bridge, (farthest in right-hand photo) which opened in 1966, was built to alleviate traffic and weight limits. It was constructed as a “twin” to the Grace Memorial Bridge with three lanes that were a bit wider, one of which was used as a reversible lane according to traffic needs. Both of these bridges are now gone and were replaced by the eight lane wide, cable-stayed design, Arthur Ravenel Jr. Bridge in 2005."
