几代谋划几代修，
                                                         几代心血付其中。
                                                         悬崖峭壁开通道，
                                                         深山岩洞度寒冬。
                                                         不顾安危排险炮，
                                                         粉身碎骨化云龙。
                                                         如今千车万辆过，
                                                         谁识前代修路翁。
