A vintage blueprint-style illustration of the old toll bridge to Anastasia Island, complete with a trolley, horse-drawn carriage, bicyclists, and strollers crossing the trestle span. Detail panels below show the swing span mechanism, a sailboat passing through the open span, and a typical trestle bent, all rendered in aged blue engineering-print tones. A fun bit of historic St. Augustine engineering history stretched across your yoga mat for every stretch and pose.
