Like its name, Bridge Attachment Mod will add a bridge that attach with your truck to help your trucks and trailers come across over rivers and waterholes. For using, you can press R or T button. This blog is about Spintires Mods for Multiplayer, so of course this mod will not break your game in anyway.
