德克萨斯州的官员已经解决了更换新休斯顿船舶桥梁项目的缺陷设计的计划，以满足安全问题，增加了近3亿美元的建造成本，最初为9.62亿美元。

4.1英里桥梁的新设计将在通道上携带一个扩大的Sam休斯顿Tollway，取代了钢结构的原始预铸混凝土亚结构。它还消除了塔架中的锚固和钢箱的计划入住摇篮。

“现有工作中有一个设计缺陷，”哈里斯县收费公路管理局执行董事Roberto Tevino说。“如果这座桥继续使用以前的设计，那些缺陷会导致一些安全问题，这可能导致了未来一些不幸的事情。”

哈里斯县专员法院批准了29150万美元contract amendment与船舶渠道构造函数LLC于11月30日继续使用更新的设计，最高乘坐567.9百万美元的合约，该县已经与建设者签署了。承包商是Traylor Brothers Inc.和Zachry Construction Corp.的合资企业

The remaining work will be done in three phases, Trevino says. First, the completion of the southbound approaches and main span, then the demolition of existing concrete pylons built for the earlier design, followed by the construction of the northbound approaches and main span. The bridge is expected to open to southbound traffic in early 2025 and the northbound bridge will open in early 2028, the authority says.

Work on the FIGG Bridge Engineers-designed segmental cable-stayed bridge initially started in 2018, but the county ordered an independent review of the plans after the collapse of a pedestrian bridge in Miami that was also designed by FIGG. Work on the Houston bridge在2020年初停止了。

As ENR previously reported, the county hired COWI North America Inc. to perform an independent review of FIGG’s design, and the firm identified 21areas of “significant concern,”包括风装，弯曲腿部区域和基础。Cowi现在是该项目记录的工程师。

Even with the added cost, the county commissioners said the work is needed to address safety issues tied to piers in the channel and the lack of shoulders on the bridge.

“我们越早可以完成这项工作，将为公众提供更安全的，”雷克霍勒在11月30日会议期间说。
