Why tf does Episcopal HS on 610 west loop close 2 lanes of traffic during afternoon rush hour???

Apologies for the mild rant, but why do these asshats get to close not one but TWO lanes of traffic of a major 3 lane road? I'd understand if they closed 1 lane, there are a lot of people exiting thag garage, but 2 lane is plain excessive. Especially during 4 PM rush traffic.

Is there anything a person can do to get them to stop? I'd be fine if they only closed one lane to help the students get out.

If their students are such bad drivers thay they have time close 2 lanes of 3 in order to turn and merge into traffic, then they shouldn't be driving at all.
