阿拉斯加苏厄德公路黑冰成患 安克雷奇以南路段路况极差
据阿拉斯加州511路况系统11月11日发布的信息，安克雷奇以南的苏厄德公路（Seward Highway）45英里至75英里路段出现黑冰与冰壳路面，路况被评为极差。511系统于当日清晨5时59分更新称，该路段靠近Hope岔路口（Hope Y）一带路面有结冰覆盖，驾驶人应减速慢行、拉长车距。安克雷奇一带当日气温在冰点上下，路面湿滑，入夜后还可能出现降雪，结冰风险进一步上升。
苏厄德公路是安克雷奇通往南部港市苏厄德的重要通道，冬季黑冰是这条山区临海公路最常见的行车隐患之一。州交通部门提醒，行经相关路段时避免急刹车与急打方向，出发前先查询511系统的最新路况。
Black Ice Makes Seward Highway Treacherous South of Anchorage
Alaska's 511 road-condition system reported on Nov. 11 that black ice and an ice crust have made the Seward Highway between mileposts 45 and 75, south of Anchorage in Anchorage Municipality, extremely hazardous. In an update posted at 5:59 a.m., the system said ice covered the roadway near the Hope Y junction and urged drivers to slow down and leave extra following distance.
Temperatures around Anchorage hovered near freezing with slick pavement, and snowfall possible in the evening could raise the icing risk further. The Seward Highway is the main road link between Anchorage and the port city of Seward, and black ice is one of the most common winter hazards on the mountainous coastal route. The state transportation department advised drivers to avoid hard braking and sharp steering on the affected stretch and to check the 511 system for the latest conditions before setting out.
