大烟山国家公园两条季节性道路11月9日迎本季最后开放日：帕森支线与里奇山路日落后关闭，另三条道路开放至11月29日
美国国家公园管理局（NPS）公布的大烟山国家公园2026年季节性道路日程显示，帕森支线道路（Parson Branch Road）与里奇山路（Rich Mountain Road）的本季开放期均至11月9日为止，两条道路将于11月9日日落后关闭，进入冬季关闭期。
两条道路均为单行道。帕森支线道路全长8英里，本季自5月1日起开放，公园管理局建议使用高底盘车辆通行；房车、巴士、长度超过25英尺的厢式车以及拖挂拖车的乘用车禁止通行。里奇山路本季自4月10日起开放，车辆限制与帕森支线相同。
关闭安排上周已先经历一段插曲：11月4日，强风吹倒树木，公园一度关闭凯兹湾环路（Cades Cove Loop Road）、切罗基果园路（Cherokee Orchard Road）与帕森支线道路；三条道路已于11月5日先后重新开放，帕森支线于当天下午恢复通行。
公园其余季节性道路的关闭日期排在本月稍后：库沃希路（Kuwohi Road）、小绿荆路（Little Greenbrier Road）与咆哮叉机动自然小径（Roaring Fork Motor Nature Trail）开放至11月29日。纽芬峡谷路（Newfound Gap Road，美国441号公路）、小河路与凯兹湾环路等主干道路全年开放，但会因天气临时关闭。公园管理局表示，季节性日期并不保证通行，出行前应查询公园官网的实时路况与关闭信息。
Under the National Park Service's 2026 seasonal road schedule for Great Smoky Mountains National Park, Monday, November 9 is the final scheduled operating day for Parson Branch Road and Rich Mountain
Both are one-way roads. Parson Branch Road is an eight-mile road whose season ran from May 1; high-clearance vehicles are recommended, and motorhomes, buses, vans longer than 25 feet, and passenger vehicles towing trailers are prohibited. Rich Mountain Road's season ran from April 10, with the same vehicle restrictions.
The closing follows a weather interruption last week. On November 4, strong winds blew trees down across the park and the park closed Cades Cove Loop Road, Cherokee Orchard Road, and Parson Branch Road. The park reopened Cades Cove Loop Road and Cherokee Orchard Road on the morning of November 5, and Parson Branch Road reopened that afternoon.
Three other seasonal roads remain open later into the month: Kuwohi Road, Little Greenbrier Road, and the Roaring Fork Motor Nature Trail are scheduled through November 29. Primary roads including Newfound Gap Road (US 441), Little River Road, and Cades Cove Loop Road stay open year-round, weather permitting. The park advises checking current conditions before driving, as weather can force earlier or temporary closures.
