Batiquitos Lagoon 铁路新桥通车：首列 Pacific Surfliner 清晨驶过，1.66 亿美元双轨工程完成 75%
11 月 9 日清晨约 5 时，一列北行的 Amtrak Pacific Surfliner 列车驶过位于加州圣迭戈县 Carlsbad 市 Batiquitos Lagoon 上的新混凝土双轨桥，这是列车首次使用这座替代 1940 年代木栈桥的新桥。Amtrak 与 COASTER 列车自此改走新桥运行。
Batiquitos Lagoon 双轨工程总投资 1.66 亿美元，全长 0.6 英里，南起 Encinitas 的 La Costa Avenue、北至 Carlsbad 的 Avenida Encinas 以北，由 San Diego 政府协会（SANDAG）与加州交通厅（Caltrans）主导，目前总体进度约 75%。新桥桥跨更宽，有利于潟湖潮流通畅与鳗草生长，并为濒危的加州燕鸥提供栖息环境。下一步施工将拆除旧木栈桥并铺设第二股道。
工程 2024 年 8 月开工，每年 4 月 15 日至 7 月 31 日因加州燕鸥繁殖季停工，预计 2028 年全部完工。这条 Los Angeles–San Diego–San Luis Obispo（LOSSAN）铁路走廊由北县交通局（NCTD）、Amtrak 与 BNSF 货运列车共用，双轨区段贯通后，走廊将形成 5.5 英里连续双轨。（来源：San Diego 政府协会）
First Train Crosses New Batiquitos Lagoon Rail Bridge: $166 Million Double-Track Project Reaches 75 Percent
At about 5 a.m. on November 9, a northbound Amtrak Pacific Surfliner train crossed the new concrete double-track bridge over Batiquitos Lagoon in Carlsbad, San Diego County, California, the first train to use the structure replacing a 1940s wooden trestle. Amtrak and COASTER trains have since shifted to the new bridge.
The $166 million Batiquitos Lagoon Double Track project spans 0.6 miles, from La Costa Avenue in Encinitas to just north of Avenida Encinas in Carlsbad, led by the San Diego Association of Governments (SANDAG) and Caltrans, and is now about 75 percent complete. The new bridge's wider spans improve tidal flow in the lagoon, support eelgrass growth and benefit the endangered California least tern. Crews will next remove the old wooden trestle and lay the second track.
Construction began in August 2024, pausing each year from April 15 to July 31 for the California least tern nesting season, with full completion expected in 2028. The Los Angeles–San Diego–San Luis Obispo (LOSSAN) corridor is shared by the North County Transit District (NCTD), Amtrak and BNSF freight trains; once the second track is in, the corridor will have 5.5 miles of continuous double track through the area.
