Is it just me or is the response time from the warning lights way too short. It seems to me that the warning lights light up red way too late. So the detection system does not function correctly for the straight forward approaching trucks with a decent speed, even while ignoring weather conditions and ignoring traffic behind the truck.Are you jerks trying to become more famous than our beloved rail overpass in Durham? (the one in the US...in NC)
The best way would be to increase the height of that bridge, but then the entire train track needs to be lifted and adjusted.

And also especially when the trucks have to turn from the right on the crossing.
No way anybody can stop and not hit that protection bar.
The best way would be to increase the height of that bridge, but then the entire train track needs to be lifted and adjusted. And of course there is probably a by regulation a maximum inclination, of the traintrack because weather situations also determine the friction between the train wheels and the traintrack.
That means a lot of traintrack has to be lifted to stay within the maximum inclination.
And it is all privatized.
With all this in mind, i guess no money available ?
Why not lower the road level under the bridge instead, and a bit before and after?
Or would it compromise the bridge?

The video explains why ... sewer line underneath ...

Why not lower the road AND the sewer line, under the bridge?
That would indeed be a good solution also, probably even cheaper than placing a new bridge and modifying the rail road tracks. But as always, there are things to keep in mind to check first. Perhaps they got sewer pipes, other pipes like for example gas pipes and all kinds of electrical cables under the road concrete. Maybe a subway lies beneath ? So there is definitely some checking, planning and keeping administration ahead needed. Also ,if the road is lowered for example about 2 feet. There is also an inclination issue with the road also because of weather conditions, extra road sewer drains at the lowest point will be needed on the sides but not in the middle or where the tires touch the concrete the most. So the road must also have a slight arc shape with the highest point in the middle to make sure that all rainwater flows towards the road sewer drains placed on the side of the road. Even with all this done, a large amount of the road in all directions needs to be modified to reach a modest inclination. And with those parts of the road a lot of other stuff as well, like for example pavement, street lighting, road sewer drains that are already present. And of course regulations that are there for a reason.Why not lower the road level under the bridge instead, and a bit before and after?

Yeah. That is sort of true. But the height of trucks is a pretty common standard, i would think for at least 60 years. Just guessing here. So the sort of idiot would really be who placed the bridge and never thought of checking of the common maximum height of (transport)trucks and leave enough leverage in height.Or people are just idiots. Plenty of signage around it, not just at the barrier.

Bridge is from 1940... Clearance of 11' 8" worked for trucks of that time. Obviously trucks got taller and this is what happens.Yeah. That is sort of true.

So, in all those 83 years and nobody ever thought of increasing the height of the bridge or lowering the road beneath it for the last 40 years ? That is disappoint.Bridge is from 1940... Clearance of 11' 8" worked for truck of that time. Obviously trucks got taller and this is what happens.
I agree with you that the adjusting the road is highly likely the easiest way.Perhaps: video didn't say, either way.
Assuming it's only sewer pipes, it's VERY doable to just re-route to before / after the bridge, or lower (???) the pipes, and then lower the road: problem solved.
If there are other types of infrastructure, then it's a VERY COMPLICATED problem to solve.
They did raise it 8", maximum allowed due to other bridges nearby.So, in all those 83 years and nobody ever thought of increasing the height of the bridge or lowering the road beneath it for the last 40 years ? That is disappoint.
