Are there any causes that can dictate the closure of 516 Arouca?

Yes, if it turns out that it is not safe to cross the 516 Arouca, due to storm, wind or other reasons, it will be closed. In these cases, the closing notice will be given on the website and official social networks and all visitors who have purchased tickets will be duly informed by email and text message. These visitors may 1) reschedule their visit at no additional cost, within a period of one year, on a date of their choice (subject to availability) or 2) request a full refund. It is recommended to check the official website and social networks beforehand, on the day you intend to visit.
