Is there a way to make a bridge hard so cars can drive on them?

Hello Bobby,The answer is yes, but the method depends on the type of bridge.Extrusion bridge: this code must be included in the xml file - suppressPlatform = "FALSE"suppressPlatform - True or False. A platform will harden the surface of the bridge so that freeway traffic can pass over it. But, large numbers of platforms will degrade performance, so it can be removed from bridges that have no traffic.gMax bridge: a platform must be attached to the bridge surface -Best regards.Luis
