4月6日，河南省信阳市新十八大街南段贯通工程、跨京广铁路转体斜拉桥塔柱封顶，该桥由在鄂央企中铁大桥局承建。
跨京广铁路转体斜拉桥，跨越京广铁路信阳编组场20股铁路股道，为150米＋150米斜拉桥斜拉索，共设置22对扇形双索面，半漂浮体系。主塔采用箱型截面，塔高84米，采用液压爬模施工，转体总吨位近2万吨。具有转体长度长，转体纵横向均为不平衡，横向称重难度大，精度要求高，技术难度大。
中铁大桥局项目部积极开展技术攻关，采用施加预应力砂筒降低临时支撑沉降量、设置双保险竖向型钢支撑、科学严密的监控等措施，实施支撑钢砂筒+锁定型钢+梁面压重技术方案，解决转体桥塔柱竖向传力、整体抗倾覆稳定性等技术难题。
