Kids, architecture is important. That’s what ISM Raceway (formerly Phoenix Raceway, in Avondale, Arizona) learned Thursday, as their parade ahead of Sunday’s NASCAR Sprint Cup race was interrupted when Kyle Busch’s hauler proved too high to clear a new pedestrian bridge. The collision comes offscreen near the 35-second mark here:

Hey @JoeGibbsRacing you couldn't wait until the 1st lap to put someone into the wall? It's because he was wearing a #12 @Blaney hat isn't it? pic.twitter.com/KRWMwZwjto — Sheree #DI9🏁🏁🏁 (@Arend_Sheree91) November 8, 2018

Sheree, who tweeted that video, added that her dad was hit by a piece flying off the hauler, but that he’s okay:

Also that piece of the hauler hit my dad @JoeGibbsRacing https://t.co/Bh9Ol01SIg — Sheree #DI9🏁🏁🏁 (@Arend_Sheree91) November 8, 2018

It was some kind of panel on top of the 18 hauler..they didn't realize the clearance from that piece and bridge https://t.co/ZdfQkdzqrG — Sheree #DI9🏁🏁🏁 (@Arend_Sheree91) November 8, 2018

Here’s a look at the hauler post-collision:

This is a pedestrian bridge that was added as part of the $178 million in renovations to the racetrack ahead of this year’s races. But it seems someone built it too low for NASCAR haulers, or at least for Busch’s hauler. Whoops.
