7、各限高点处派专人24小时轮流执勤。
8、现场文明施工：施工路段内局部采用彩钢瓦隔离施工。以上所有照明灯均由我部自购200KW发电机供电。
〔二〕下部结构施工
1、全真观1、2号大桥：
全真观1号大桥上跨G209为五号墩及六号墩之间，全真观2号大桥上跨G209为二号墩及三号墩之间，桥墩基础为桩柱式，因图纸对此段国道进行了改道设计，需要改道完成可以通车后，派专人负责安全工作，指挥过往车辆。施工时机械操作严格按照有关规程操作，特别注意不要对过往车辆和行人造成危险，位于原G209位置的桩基方可以钻孔。
2、孤山1、2、4、5、7、8号桥
孤山1号大桥上跨G209为五号墩及六号墩之间，孤山2号大桥为一号墩及二号墩之间，桥墩基础为桩柱式；孤山4号大桥为五号墩及六号
