@dostovel, you may already be aware of this. In case you are not…when you design your bridge you will want to make sure that the width accommodates a cart. On the Google Drive, look in the directory Spice-Vendors-House/Scenes/Models/WIP/Accessories/ACC_Standalone. Kent originally created the *.blend files with proxy assets that were positioned and scaled for proper placement of our work. For example, in any of the WIP_acc_cart*.blend files you will likely find a PRX collection with the mock objects that defines the cart. You could use that in helping to define your bridge width.
