IIRC, they didn’t raise it because of the crashes. It’s a privately owned rail line and they don’t care about that because the bridge itself wasn’t being damaged. It needed to be renovated anyway so they raised it to be level with the nearby at-grade crossing while they were at it.
This is the final push I needed to switch to GrapheneOS. Thanks Google! Now, if only I didn’t have to give Google money for the Pixel so I can install GrapheneOS.
