These are photos from a cruise on the Matanzas River in St. Augustine. They show the Bridge of Lions from the water, including the working drawbridge.
Drawbridges are still common in coastal Florida since there’s so many barrier islands, most of which are not in areas of large ship traffic. So bridge-keeper is still a profession in the Sunshine State.
One of the interesting features of the bridge concerns the blue and red lights located at the point where the bridge separates. Notice how they rotate so the lights continue to point down.
The Matanzas River is only 23 miles long and it part of the Intracoastal Waterway.
