In the scene about driving to the guest house in Rodanthe, Dr. Flanner is depicted crossing a large bridge after taking a ferry. This is impossible. There is no large bridge of any kind between the ferry on the southern coast of Hatteras Island and Rodanthe, located to the north, mid-way on the island. The bridge shown was actually the Herbert C. Bonner Bridge, a two-mile span connecting Hatteras Island to the northern Outer Banks, which is the direction the character was headed, meaning he went past Rodanthe several miles earlier. Maybe he missed it in the fake sand storm.
