2007年1月27日上午,河北省承唐高速公路唐山段一期工程唐山至南小营段正式竣工通车。至此,唐山高速公路通车里程达到306公里,实现了300公里的突破,高速公路密度为每百平方公里2.25公里,达到发达国家水平。
此次竣工通车的承唐高速公路唐山段一期工程于2004年底开工建设,全长18.46公里,起点在唐山市西外环高速公路终点,终点位于遵化市党峪镇南小营村,与112国道相接,为双向四车道,总投资5.6亿元。
承唐高速公路唐山至南小营段的竣工通车,为唐山与承德之间构筑了一条快速通道,进一步提高了我省北部地区路网水平,加快了北部地区融入沿海经济发展的步伐,对改善冀东北地区交通状况,引领三北地区的资源、产业向沿海聚集具有重要意义。
2010年11月8日,河北省承唐高速公路唐山段二期工程正式建成通车。
长深公路遵化(承唐界)至南小营段高速公路起于遵化市侯家寨乡甘渣峪村的承唐交界处,沿线跨越大秦铁路、潘遵铁路、唐遵铁路、东沙河、黎河、省道邦宽线和国道112线,向南与已建成的唐山至南小营段高速公路相接,路线全长43.655公里,其中遵化南互通立交以北23.334公里为双向六车道,以南20.321公里为双向四车道。全线共设互通式立交4座,分离式立交16座,大中桥29座,隧道1座,主线收费站1处,服务区2处。该项目是唐山公路建设史上第一条山区高速公路,全线百米以上开山段有13处,山体开挖土石方量达130多万立方米,另有18处1080米铁矿采空区,全部需要进行特殊处理,桥隧比达18%。 2010年11月8日上午11时,河北省承唐高速公路承德段通车仪式在承唐界主线站举行。
承唐高速承德段起自承德市双滦区陈栅子乡大栅子村,与京承高速公路相交,途径安匠、刘杖子、李家营、白马川、半壁山,止于承德与唐山交界处。全线采用双向六车道标准,设计时速80公里,路线全长82.3公里,国家核准总投资62.6亿元。于2004年9月29日经省发改委批准立项,2005年12月31日获得国家发改委《工程可行性研究报告》的批复, 2007年8月30日交通部批复了《初步设计》,2007年10月30日开工建设。该项目地处燕山腹地,沿线山高壑深,河流曲折动用土石方2400万立方米,建设桥梁全长19.2公里,共90座,最高的桥梁71米,其中最长的偏道沟2号桥长1211.6米,隧道全长13.2公里,共16座,其中最长的五道岭隧道单洞长3160米。全线设安匠、李家营、白马川、半壁山服务型互通4处。
