If road opened then closed briefly again, the earliest opening and latest closing date is used. Days open refers to the number of days between these dates and does not reflect closures within these dates. For example, in 1999 the pass was closed from Nov. 18-Dec. 23, but the "days open" figure includes these 35 days that it was closed. |
