歷史：

據舊志記(ji)載，為(wei)南宋寶祐(you)年(nian)(nian)(nian)(nian)間（1253年(nian)(nian)(nian)(nian)～1258年(nian)(nian)(nian)(nian)）同里(li)人葉茵建造。該橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)至(zhi)(zhi)今已有七百(bai)多年(nian)(nian)(nian)(nian)，為(wei)全鎮保存最(zui)(zui)完(wan)善、最(zui)(zui)古(gu)老(lao)的(de)拱橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)。思本橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)架(jia)于(yu)橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)港(gang)中(zhong)段，東西走向，系單(dan)孔拱形橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)。橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)身皆用(yong)武(wu)康(kang)石(shi)(shi)(shi)砌成(cheng)。橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)全長22.5米(mi)(mi)，寬1.8米(mi)(mi)，橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)面長5.4米(mi)(mi)，略呈弧形，橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)跨度達(da)9米(mi)(mi)，矢(shi)高4.5米(mi)(mi)，其(qi)(qi)矢(shi)跨正好為(wei)1∶2，拱圈(quan)呈半(ban)圓(yuan)形。該橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)具(ju)有獨特的(de)形體結構和架(jia)橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)技術。在橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)東西兩邊斜坡和橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)面北側(ce)，用(yong)三塊(kuai)大(da)型的(de)條(tiao)石(shi)(shi)(shi)銜(xian)接，條(tiao)石(shi)(shi)(shi)每塊(kuai)長為(wei)4.4米(mi)(mi)，寬0.73米(mi)(mi)。兩側(ce)石(shi)(shi)(shi)條(tiao)則鑿成(cheng)階沿，與相并石(shi)(shi)(shi)階高低寬狹一(yi)致。如此構造，不僅能夠顯示其(qi)(qi)形體特色，更對維(wei)護整座(zuo)橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)梁免致坡側(ce)傾斜，起到(dao)極好的(de)固(gu)定作(zuo)用(yong)，所(suo)以至(zhi)(zhi)今雖(sui)未經修葺而保存完(wan)好。歷經七百(bai)余年(nian)(nian)(nian)(nian)風(feng)雨的(de)古(gu)橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)，至(zhi)(zhi)今兩旁(pang)遍披青(qing)藤枝蔓，微(wei)露半(ban)軌橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)孔，屹(yi)立(li)在盈盈綠水之(zhi)上。該橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)1995年(nian)(nian)(nian)(nian)4月被(bei)列為(wei)江(jiang)蘇(su)省級文物(wu)保護單(dan)位(wei)，是蘇(su)州市吳江(jiang)區境(jing)內(nei)現存最(zui)(zui)古(gu)老(lao)的(de)橋(qiao)(qiao)(qiao)(qiao)(qiao)(qiao)之(zhi)一(yi)。
