BART 已完成其 Transbay Tube 的 15 亿美元抗震改造，Transbay Tube 是奥克兰和旧金山之间重要的水下铁路连接线，标志着该隧道建成 50 周年。 BART has completed a $1.5 billion seismic retrofit of its Transbay Tube, a vital underwater rail link between Oakland and San Francisco, marking the tunnel's 50th anniversary. 升级加强了结构完整性,并包括一个新的抽水系统,以管理重大地震期间可能出现的漏水情况。 The upgrades enhance structural integrity and include a new pumping system to manage potential leaks during significant earthquakes. 虽然目前设计该管可承受千年中一次地震事件,但BART面临持续的财政挑战,因为大流行后骑手人数减少。 While the tube is now designed to withstand a once-in-a-thousand-year seismic event, BART faces ongoing financial challenges due to reduced ridership post-pandemic.
