Waterways in New Jersey remain covered in ice despite a recent warmup, creating concerns for marina and restaurant owners in Highlands.

Business owners say Mother Nature can be unpredictable for those who rely on the Jersey Shore. This winter has been especially challenging for Bahrs Restaurant in Highlands.

Drone video shows ice taking over the marina behind the restaurant. The ice is so thick that it is lifting some pilings and damaging marina infrastructure.

Owners say the biggest concern is what may happen to the docks once the ice begins to thaw. The ice remains thick, making it difficult to measure the extent of the damage, but it will eventually melt.

The owner of Bahrs Restaurant says he has never seen anything like this.
