Here's an article/video from a local news source that better explains what happened and who the lawsuit calls out as liable for the accident.
Seems there are possibly two entities that could be liable for the accident.
A. The developers...they did not turn over responsibility of roadwork to the NC DOT after the subdivision was completed, and had no road maintenance plan in place. This also means they would be responsible for marking the roadway that the bridge was out.
B. Google...they had multiple requests to change the map to indicate the bridge was out, and they didn't update their maps. Even Mapquest and Apple Maps have their maps updated.
Thank you for the additional source. So, there wasn't any signage, barriers, or lighting, AND it was dark and raining AND Google had multiple requests and 10 years to fix it AND other services have it properly marked. Maybe people should slow their roll and stop dismissing the case out of hand?
