一高速公路历经三年建成投入试运行,分三个合同段分别由三家施工单位完成。现建设单位委托某环评单位进行竣工验收调查。公路沿线高填方路段约30km、深挖方路段17km、隧道2km,其他40km。建成互通式立交2处,有大桥、特大桥3处跨越3条河流,其中一河为饮用水源地,公路附近有一药材基地,原设计不占用该药材基地,但实际占用了5hm2。其沿线有收费站7处、服务区3处,经过A、B、C、D、E共5个村镇,其中距路肩500m有一小学,被公路与一村C集中居民区隔开。原环评提出应在A村段设置声屏障,调查时未设,但现状监测交通噪声不超标,未对沿线居民造成影响。工程比原设计增加占地30hm2,设计时设置取土场13处、弃土弃渣场5处。实际车流量不足设计车流量的40%。
