歷史：

據舊志記載，為(wei)(wei)南(nan)宋寶祐年(nian)(nian)(nian)間（1253年(nian)(nian)(nian)～1258年(nian)(nian)(nian)）同里人葉茵建造。該橋(qiao)(qiao)(qiao)(qiao)至今(jin)已有(you)七(qi)百(bai)多年(nian)(nian)(nian)，為(wei)(wei)全鎮保存最完善、最古(gu)老的拱(gong)(gong)橋(qiao)(qiao)(qiao)(qiao)。思(si)本(ben)橋(qiao)(qiao)(qiao)(qiao)架于橋(qiao)(qiao)(qiao)(qiao)港中段，東(dong)西走(zou)向，系單孔(kong)拱(gong)(gong)形(xing)橋(qiao)(qiao)(qiao)(qiao)。橋(qiao)(qiao)(qiao)(qiao)身皆用(yong)武康石(shi)(shi)砌成(cheng)(cheng)。橋(qiao)(qiao)(qiao)(qiao)全長(chang)22.5米，寬1.8米，橋(qiao)(qiao)(qiao)(qiao)面長(chang)5.4米，略呈弧形(xing)，橋(qiao)(qiao)(qiao)(qiao)跨度達9米，矢高4.5米，其矢跨正好(hao)為(wei)(wei)1∶2，拱(gong)(gong)圈(quan)呈半(ban)圓形(xing)。該橋(qiao)(qiao)(qiao)(qiao)具有(you)獨特(te)的形(xing)體(ti)結(jie)構和架橋(qiao)(qiao)(qiao)(qiao)技術。在橋(qiao)(qiao)(qiao)(qiao)東(dong)西兩(liang)邊斜(xie)坡和橋(qiao)(qiao)(qiao)(qiao)面北側(ce)，用(yong)三塊大型的條(tiao)(tiao)石(shi)(shi)銜接，條(tiao)(tiao)石(shi)(shi)每塊長(chang)為(wei)(wei)4.4米，寬0.73米。兩(liang)側(ce)石(shi)(shi)條(tiao)(tiao)則(ze)鑿成(cheng)(cheng)階沿，與相并(bing)石(shi)(shi)階高低寬狹(xia)一致(zhi)。如此構造，不僅能夠(gou)顯示其形(xing)體(ti)特(te)色，更(geng)對維護(hu)整座橋(qiao)(qiao)(qiao)(qiao)梁免致(zhi)坡側(ce)傾斜(xie)，起(qi)到(dao)極好(hao)的固定作用(yong)，所以至今(jin)雖未(wei)經(jing)修葺(qi)而(er)保存完好(hao)。歷(li)經(jing)七(qi)百(bai)余年(nian)(nian)(nian)風(feng)雨的古(gu)橋(qiao)(qiao)(qiao)(qiao)，至今(jin)兩(liang)旁遍披青藤(teng)枝蔓，微露半(ban)軌橋(qiao)(qiao)(qiao)(qiao)孔(kong)，屹立在盈盈綠水之上(shang)。該橋(qiao)(qiao)(qiao)(qiao)1995年(nian)(nian)(nian)4月被列為(wei)(wei)江蘇(su)省級文(wen)物保護(hu)單位，是蘇(su)州市(shi)吳江區(qu)境內現存最古(gu)老的橋(qiao)(qiao)(qiao)(qiao)之一。
