三元桥(2009年)

三元桥或三元立交桥是北京三环路东北角的一座重要立交桥,为三环路同101国道北京机场高速公路的交汇桥。1984年,中华人民共和国35周年时建成。[1] 全桥长54.3米,桥面宽度为44.8米,设计为3上3下车道,两边是非机动车道。进入21世纪,路政部门又压缩了部分非机动车道宽度,将这里扩展为5上5下车道格局。 《北京市朝阳区地名志》中的“三元桥”条目说:“因附近原有三元庵故以三元定桥名”。[2]

2015年11月13日至11月15日,因被评定为D级(不合格状态)[3],三元桥断路换梁[4]。原计划将旧梁整体移走,但由于旧梁状态较原先设想更差,因而工程人员改为现场分块拆除旧梁后再整体安装新梁,换梁工程持续时间也因此由原计划的24小时延长至43小时[5]
