9月28日，由中交(jiao)公規(gui)院(yuan)和中交(jiao)路建(jian)(jian)共(gong)同投資的清(qing)西大橋及接線工程建(jian)(jian)成通車。大橋由中交(jiao)公規(gui)院(yuan)設計、中交(jiao)路建(jian)(jian)施工建(jian)(jian)設。

清(qing)(qing)遠市清(qing)(qing)西大(da)橋(qiao)(qiao)及(ji)接(jie)線工(gong)(gong)程位于清(qing)(qing)遠市境內(nei)，南連廣(guang)清(qing)(qing)高(gao)速公(gong)路，北接(jie)清(qing)(qing)連高(gao)速公(gong)路。工(gong)(gong)程全長(chang)(chang)約17公(gong)里，設(she)特(te)大(da)橋(qiao)(qiao)3座，大(da)橋(qiao)(qiao)、中橋(qiao)(qiao)、小(xiao)橋(qiao)(qiao)20座，涵洞通(tong)道40道，互通(tong)立交(jiao)5處，回瀾停車區1處，主(zhu)橋(qiao)(qiao)采用(yong)連續剛(gang)構，最大(da)懸(xuan)臂長(chang)(chang)度89米，采用(yong)掛籃對稱懸(xuan)臂澆筑施工(gong)(gong)。

該工(gong)(gong)程(cheng)(cheng)地質條(tiao)(tiao)件(jian)復(fu)雜，群樁(zhuang)基礎樁(zhuang)位遇溶(rong)率達(da)100%，巖(yan)溶(rong)樁(zhuang)最(zui)(zui)大(da)線巖(yan)溶(rong)率為(wei)88.4%，單個(ge)溶(rong)洞(dong)(dong)(dong)最(zui)(zui)大(da)高(gao)度21.4米(mi)，最(zui)(zui)大(da)單樁(zhuang)溶(rong)洞(dong)(dong)(dong)累計高(gao)度31.4米(mi)，施(shi)工(gong)(gong)難(nan)(nan)度極大(da)。建設過程(cheng)(cheng)中，項目團隊克服征地拆(chai)遷(qian)難(nan)(nan)度大(da)、地質條(tiao)(tiao)件(jian)復(fu)雜、施(shi)工(gong)(gong)條(tiao)(tiao)件(jian)艱苦等(deng)各種困難(nan)(nan)，超前策劃、科學組(zu)織、精心管理、創新(xin)工(gong)(gong)藝，全力開展(zhan)科技(ji)攻(gong)關，探索出了一整(zheng)套成熟的溶(rong)洞(dong)(dong)(dong)基樁(zhuang)處(chu)理工(gong)(gong)藝。

清西大(da)(da)橋及接(jie)線工(gong)程是粵港澳大(da)(da)灣區(qu)北向(xiang)輻射廣大(da)(da)內地的(de)(de)重要交通要道和經(jing)濟走廊，建成通車后(hou)將與廣清高(gao)速(su)(su)、清連高(gao)速(su)(su)共(gong)同(tong)構成廣東省南北向(xiang)交通大(da)(da)動脈，實現(xian)廣東省高(gao)速(su)(su)公路網(wang)規劃中“六縱線”全線貫通，將進一步(bu)加(jia)強珠(zhu)三角經(jing)濟區(qu)對清遠北部(bu)及內陸(lu)省份(fen)的(de)(de)輻射能力。
