　　10月17日讯　日前，由临川公路分局管养的东馆桥危桥重建工程开工，老桥以于10月10日顺利拆除。重建后东馆桥设计荷载为公路-Ⅰ级。新桥桥面宽度为11.0m（行车道）+2×0.5m（防撞栏），桥面宽为12米，全长67.0米。桥孔具体布置为3×20m预应力砼简支小箱梁。下部构造中，两岸桥台采用桩基接盖梁的轻型桥台，桥墩采用桩柱接盖梁，基础采用钻孔灌注嵌岩桩设计。工程投资为280万元，施工工期为4个月。

　　据悉，东馆桥建成于1964年，近年来由于交通量逐渐增大、大吨位车辆不断增多再加上修建年限早，导致该桥桥墩严重下沉、桥台两头路面下沉，跳车等现象，给过往车辆和行人带来极大的安全隐患，鉴定为四类危桥。临川公路分局积极协调筹措资金，加快重建确保该桥安全畅通。为了确保过往车辆能够正常通行，施工单位在老桥东面架设了一座临时钢便桥。便桥便道两端均设置了简易护栏和安全标志，进出口处设置了限载10吨的标志牌并安排了专人值守。为了确保施工段交通畅通，聘请了交通协警维护交通。
