This is a small plugin that adds a 2-tile wide highway and an expressway which can go all the way up to max bridge height. Tunnels and constant height option is available. The bridge has 2 texture options. Credit to devs for road and bridge textures this plugin is based on. Free version on forum (just search up the same name) the plugin is currently pending approval on plugin store, please tell me if something is wrong/you have ideas for better pricing.
