Spent a few years driving over the old bridge twice daily on my commute to work and back, then the new bridge shown "still standing" in the last still shot.
The old Jamestown bridge was two very narrow lanes with a open steel grate roadway at the top span. It was not a fun drive in the dead of winter during freezing rain and snow in my overpowered Mustang GT.
