Hmm the ones here in LA still have lights on them :) Well you can just create a custom gantry using the gantry kits available. That's why I don't make premade ones anymore. Honestly you can build it manually using procedural objects, then just copy and paste over and over again in your city. That's what I do :)

These pre-made gantrys are amazing... would you consider making another set of these without the platform and lights? The new CA gantrys no longer have platforms and lights now that they're using reflective overhead signs now. I'd be willing to patreon some money to help!!
