Turret at Castillo de San Marcos National Monument(circa 1680) with Flagler College (former Hotel Ponce de Leon) tower (r) and Memorial Presbyterian Church tower (l). December 2009
"The massive Main Street "vertical lift span" Bridge ... was built in the 1930s to carry US 1 over the St. Johns River. Made of eleven steel stringer spans and three Warren through trusses, the 365-foot long continuous truss vertical lift span at the center is the longest in Florida. The span-drive system, which puts the drive machinery on the movable span, utilizes concrete counterweights enclosed within two large steel frame towers. Although builders emphasized functional considerations, the bridge produces an aesthetic effect through its strength, 200-foot high lift towers, and commanding reach across the St. Johns River measuring 1,680 feet in length." http://bridgepros.com/projects/mainst.Jax/Mainstreet.htm
