Caltrans关闭203号州道主旅馆以西路段：冬季封路至明年春季
加利福尼亚州交通厅（Caltrans）11月3日宣布，莫诺县203号州道（State Route 203）猛犸山主旅馆（Main Lodge）以西路段即日起冬季封路，车辆无法再继续前往 Minaret Vista 及 Reds Meadow 一带，封路将持续整个冬季。
这次季节性关闭影响的路段从猛犸山主旅馆向西一直到 Minaret Vista 的莫诺县界。Caltrans 提醒，封路不影响前往猛犸湖镇（Mammoth Lakes）本身，也不影响前往滑雪区：驾驶人仍可沿203号州道从395号公路经镇内前往主旅馆，只是不能再向西深入。
夏季，这段公路是通往魔鬼岩柱国家纪念地（Devils Postpile National Monument）与彩虹瀑布（Rainbow Falls）等东塞拉热门景点的主要通道；冬季封路后，这些地点将无法以普通车辆抵达。Caltrans 第九区表示，高海拔地区的大雪与严峻天气使冬季例行维护无法进行，这类季节性关闭是该区每年冬季封路安排的一部分，路段通常要到春季、 施工队完成清雪并评估安全状况后才会重新开放。
Caltrans 尚未给出具体的重开日期，驾驶人可通过该厅 QuickMap 服务查看实时路况与后续封路更新。猛犸山滑雪区方面也同步转发了这项官方封路通告。

Caltrans Closes State Route 203 Beyond Mammoth Mountain Main Lodge for the Winter
The California Department of Transportation (Caltrans) announced on November 3 that State Route 203 beyond the Mammoth Mountain Main Lodge in Mono County has closed for the winter season. The seasonal shutdown ends vehicle access west of the ski area's Main Lodge toward Minaret Vista and the Reds Meadow area for the duration of the winter.
The closure covers the stretch of State Route 203 from the Main Lodge west to the Mono County line at Minaret Vista. Caltrans noted that the closure does not affect access to the town of Mammoth Lakes itself, nor to the ski area: motorists can still travel on State Route 203 from U.S. Highway 395 through town up to the Main Lodge, but can no longer continue further west.
In summer, this stretch of highway is the main vehicle access to popular Eastern Sierra destinations such as Devils Postpile National Monument and Rainbow Falls; with the winter closure in effect, those areas are inaccessible by regular vehicle traffic. Caltrans District 9 said heavy snowfall and severe high-elevation conditions make routine road maintenance impractical throughout the winter, and that the shutdown is a standard part of its annual winter road closures. The route typically remains closed until spring, when crews can clear snow and assess safety conditions before reopening.
Caltrans has not provided a specific reopening date. Drivers can monitor road conditions and further seasonal closure updates through the department's QuickMap service. Mammoth Mountain also shared the official closure announcement.
