The bridge was built at the end of the 1930s and opened in July 1941 at a cost of $1.5 million. In 1957, it was named after Mayor John T. Alsop, Jr., but continues to be known, even on road signs, as the Main Street Bridge.

The bridge is made of 11 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, powerful 200-foot high lift towers, and graceful reach across the St. Johns River.

Visit Instructions:
1) After you've found a vertical lift bridge, go visit it, get the coordinates, a picture or two of it, and if it is in use or not still as a lift bridge.
Then log it and post your pictures! At least one of the photos must be of you and your GPS there with the bridge in the background. (No old vacation shots or photos off the internet!)
2) Include the coordinates, city/county/state/country and the name of the bridge (if it has one).
3) Include any interesting information about the structure
