Tioga Roadの除雪

NPSによると、今年のTioga Roadの除雪(4/15に開始)には、かなり時間がかかりそうです。
There is no estimated opening date for 2005.
Plowing of the Tioga Road will begin on April 15th (and on April 18th for the Glacier Point Road). As of March 1, snowpack is significantly above average and, based on wind conditions this winter, it’s expected that many trees will be down (but covered by snow), which could slow plowing operations.
