西雅图轻轨西线延伸段设计公布：取消一站省逾20亿美元，2035年通车后往市中心约16分钟
海湾交通局（Sound Transit）近日发布西西雅图轻轨延伸段的"飞越"虚拟导览视频，带领公众预先"乘坐"这条未来的轻轨 3 号线，从重建的 SODO 站一路行至西西雅图的阿拉斯加枢纽站（Alaska Junction）。该项目预计 2035 年通车。
据《铁路时代》（Railway Age）10 月 13 日报道，这段延伸线全长 3.9 英里，将新增 SODO、德尔里奇（Delridge）和阿拉斯加枢纽三座车站，是选民 2016 年 11 月批准的区域交通系统扩建计划的一部分。此次发布的虚拟导览标志着项目今年 7 月达到 30% 设计里程碑，导览中的三维模型还纳入了实地勘察获得的站点地质信息。3 号线接入区域轻轨网络后，阿拉斯加枢纽至西湖站（Westlake）的车程将从约 30 分钟缩短至约 16 分钟。
海湾交通局表示，过去 18 个月项目工作的重点是寻找降低成本、减小社区影响的办法，其中最显著的变化是取消阿瓦隆站（Avalon Station）。取消该站后，更多路段改为隧道形式，工程征地数量随之减少。海湾交通局称，在保留 SODO、德尔里奇和阿拉斯加枢纽三站的前提下，项目共找到逾 20亿美元的成本节省。
海湾交通局还表示，未来几个月将与联邦交通管理局确认这些设计调整，并继续就车站设计与接驳、车站周边开发、公共艺术和施工规划征求社区意见。

Sound Transit Unveils Virtual Tour of West Seattle Link Extension; Dropping One Station Saves Over $2 Billion
Sound Transit has released a "flyover" virtual tour of the West Seattle Link Extension, taking viewers on a simulated ride on the future Link 3 Line from a reconstructed SODO station to the Alaska Junction Station in West Seattle. The project is expected to open in 2035.
According to Railway Age's October 13 report, the 3.9-mile extension will add three new stations — SODO, Delridge and Alaska Junction — and is part of the regional transit system expansion approved by voters in November 2016. The tour represents the project's progress in reaching the 30 percent design milestone in July, rendering design decisions into a 3D model that includes site-specific geotechnical information gathered through fieldwork. When the 3 Line connects to the regional light rail network, travel time between Alaska Junction and Westlake will drop from approximately 30 minutes to about 16 minutes, the transit agency said.
Sound Transit reported that over the past 18 months, work on the project has focused on identifying, evaluating and implementing measures to reduce project cost and community impacts. The most notable change is the removal of Avalon Station; eliminating it shifts more of the route to a tunnel, reducing project cost and community impacts as well as the number of properties needed for construction. In total, the agency said it identified over $2 billion in cost savings while keeping stations at SODO, Delridge and Alaska Junction.
Sound Transit said it will work in the coming months to confirm these design refinements with the Federal Transit Administration, and will continue engaging communities on station design and access projects, development near stations, public art and construction planning.
