They tried an electronic warning sign that lights up when a truck is too tall, but drivers still can't resist the lure of the hungry bridge: https://youtu.be/YQssl0sM9As?t=6 https://youtu.be/YQssl0sM9As?t=6, https://youtu.be/cZrOcCXNq5c?t=5 https://youtu.be/cZrOcCXNq5c?t=5, https://youtu.be/iQfSvIgIs_M?t=32 https://youtu.be/iQfSvIgIs_M?t=32 Might have been better off erecting a giant, no-tech billboard picturing a previous crash. But your projected water screen is awesome - they could buy one and play footage from these youtube videos while they wait on the red light.

I think the difference is that the Sydney one is very clearing telling you, the driver, to stop right now. The 11 foot 8 bridge one just looks like a generic message to all truck drivers that they should turn if they happen to be too tall. It isn't clear that it only turns on when it detects a too tall truck. If the driver of the truck thought that the bridge was too low, they wouldn't try to go under it in the first place.

  Ye it should say "Your truck is too tall" instead of a general "overheight must turn around" (it is quite obvoius what you need to do so it just wastes space).

  The difference is the Sydney tunnel is at the end of an access road where the only way to go is the tunnel, while this bridge is around a corner and driving straight ahead with a vehicle that is too tall is allowed.

That water curtain and projector looks like something adapted from the casino, convention center and special event industry.

Why don't they make the red light stay red until the truck goes away if they already have the sensors for it ?

  Because if the truck is behind a car it can't go away until the car goes under the bridge.

  Presumably the truck is already at the intersection, so it's unlikely it can actually move out of the way before the light turns green. In the first video, the truck was 3 cars back. That means that it more than likely had no room to turn away until the cars in front of it went. Seems to me that's the idea behind the setup. You put on a long red light -- long enough that hopefully the truck driver would notice the lit up sign and realize that he need to do whatever he can to make a turn when possible. Trouble is that for some people the light would have to be 10+ minutes long before they would notice that it's still red.

That's a total usability fail. "OVERHEIGHT MUST TURN" doesn't tell you that YOU, the driver currently approaching the bridge, are the one in control of a too-tall vehicle. I wonder if they've tried something as obvious as a static sign that says "LOW BRIDGE: CHECK YOUR HEIGHT", or a vehicle-activated sign that says "YOUR VEHICLE IS TOO TALL FOR THIS BRIDGE"
