The san_andreas_bridge.zip file you have requested: Map Mods / San Andreas Bridge - 1.26mb is not available. Perhaps try browsing all files for the game Grand Theft Auto: San Andreas and upload any files you want to share or are missing. This is the only information we could locate:
Here is a modification that will add a bridge over San Andreas so that CJ can easily reach the other side. This would make it easier to get to the other side of San Andreas, but would take the fun out of the game (no offense to the Author). Please note that it is highly recommended that you back up any files, just in case either you mess up your game or you do not like this modification.
