(Bridge Hunter, John A. Weeks III, no John Marvig, 3D Satellite)
While watching the video below, I could not identify what type of drawbridge was over the Black River, even when I looked at a 3D Satellite image. It seemed to be a Scherzer rolling lift bridge, but I could not clearly identify the quarter-round rolling members, even in the photos on Bridge Hunter. But John's photo below clearly shows a rolling member. I didn't know they still built this design.
The predecessor bridge was a swing bridge. So the US Coast Guard has been successful in getting a swing bridge removed from the Mississippi River. But John explains that this channel is used by recreational boats. Commercial (barge) traffic uses the west channel. When I looked at the satellite image, it appeared the Black River was just another channel of the Mississippi River. John explains "the Black River was once a separate river in this area, but it was captured a few miles up river by the Mississippi a few centuries ago." [Weeks-#7]
(new window) They get to the bridge at about 4:06. It sounds like the private car has a flat wheel.
