  据介绍,阳信高速是广东省境内连接阳江市和茂名市的高速公路,线路全长约142公里,采用双向六车道高速公路标准建设,设计速度为120公里/小时。

  据了解,该项目建成后,将接入汕湛高速、包茂高速和云茂高速,并与中阳高速、南玉高速、深中通道等一起形成连接广西西部、粤西中部至粤港澳大湾区主要城市的快捷通道,对完善广东省高速路网、落实广东省委省政府“推进乡村振兴战略”等战略部署具有重要的推动作用。

  泮水塘大桥由中铁南方投资、中铁六局承建,其桥址位于茂名高州市大坡镇境内,所处区域属剥蚀丘陵地貌,拟建桥梁跨沟谷农田,桥址区地形起伏较大,沿线路地形呈缓“V”字形,两侧山体较陡,沟谷较平缓,地面标高介于191米至252米之间,相对高差约61米,地表植被茂盛,有农田,主要为桉树、杂树及杂草灌木。

  中铁六局介绍,泮水塘大桥为双桥线,左幅长246.4米,设计孔数孔径为(830)米预应力混凝土简支(桥面连续)小箱梁;右幅长246.4米,设计孔数孔径为(830)米预应力混凝土简支(桥面连续)小箱梁,桥梁跨越村庄。(完)
