Lane Construction Corp. crews, which completed a $56.5-million widening of Interstate 40 near Mt. Juliet, Tenn., in 2014, are back at the site, repairing the highway and adding drainage after repeated hydroplane-related wrecks.

田纳西州运输部在当地警察和田纳西州高速公路巡逻队警告中增加了沉船,审查了设计建造工作的计划和建设,发现“设计没有足够的排水结构,道路建造过太平坦了TDOT发言人希瑟·詹森(Heather Jensen)说:“要指导雨水径流。”

她说,车道的工作人员正在增加两个12英寸宽,100英尺的沟渠,以改善问题区域的水收集,在威尔逊县附近的英里标记226附近。

她说,“目前,目前有沿盆地沿着中位数捕捞”。

大约有1,900英尺的内部车道被铣削并铺设,以改变道路的横向。她说:“这些变化将提供从内部车道到中间的更积极的排水。”

最初的工作将6.5英里的州际段扩大到了八个12英尺的旅行车道,其中有12英尺的肩膀铺成了12英尺的铺砌,并且在外面的肩膀上铺好了10英尺。

詹森补充说:“外部车道上的道路肩膀,远离中位数,按照设计。”维修始于10月2日,但尚未设置完成日期。詹森说:“工作人员将继续工作,直到完成工作为止。”

Asked about costs of the repairs, Jensen said Lane "is working with subcontractors to determine overall costs. TDOT believes Lane Construction is responsible for the work" and hasn't billed TDOT.

In early August, after the TDOT review, Jensen said TDOT and Lane Construction were working "to resolve the issue in a timely manner and to avoid legal action." Both sides started meeting at that time to find a solution to the problem.

Lane的发言人Lauralee Heckman说,TDOT和LANE“仍在讨论中”,以及有关问题根源的调查正在进行中。她说,维修费用仍然未知。
