I'm not saying they should pay some extra toll for that stretch of road, I'm just pointing out that they're not paying for the damage they're causing. The school or the kids aren't receiving money for the damage that's caused by the pollution from those cars.
If that's the case, I don't think it is their fault. The tax collectors should then distribute the taxes they collected in a different way.
Also, it stands to debate of the kids are forced to live in the pollution.
While the article mentions that the school was there before the highway, the students were probably not born yet. So they (or their parents) made a choice to live there and go to that school.
