4”蒼梧（龍眼咀）至碩龍高速公路的重要組成部分，是列入廣西“十二五”規(guī)劃的前期工作項目之一。本項目東聯(lián)梧州至貴港高速，西接隆安至碩龍高速，既是橫貫廣西中部東西向的交通大通道，又是連接云南、廣西、廣東等西南省區(qū)的省際通道，還是我國西南出入邊境的國際通道。本項目采用 BOT+EPC 的建設(shè)模式，項目投資人為中國交通建設(shè)股份有限公司，由其旗下的中交路橋建設(shè)有限公司、中交第一航務(wù)工程局有限公司、中交第四航務(wù)工程局有限公司和中交第二公路勘察設(shè)計研究院有限公司組成聯(lián)合體，共同出資成立廣西中交貴隆高速公路發(fā)展有限公司作為本項目法人，具體承擔(dān)本項目的投資、建設(shè)和運(yùn)營等事項。根據(jù)中交貴隆高速公路發(fā)展有限公司下發(fā)的《貴隆高速公路勘察設(shè)計段落劃分及進(jìn)度安排會會議紀(jì)要》精神，本項目勘察設(shè)計工作由中交二公院、中交公規(guī)院以及中交路橋設(shè)計分公司三家單位共同承擔(dān)，其中中交二公院為總體設(shè)計單位，并負(fù)責(zé)全線交安設(shè)施、環(huán)保景觀、機(jī)電工程、房建工程的勘察設(shè)計。
