We went through 4 swing bridges today. While I was driving and Shane was going to operate one of them, a family of swans passed by and swam under it before he’d reached it. No obstacle for them! I operated two, one large one with electronic control and warning gates for traffic on both sides for the bridge dropping and raising before and after the bridge moved, all quite slow, but easy. No cars came anyway. The other was the opposite: a small footbridge with no gears or winding mechanism, it just had to be swung manually. There was a large protruding bar to help with the leverage and was the obvious place to push, but strangely once open that bar was completely over the water which made it hard to get a good position to pull it back into place.
