Austin has a website that is crowd sourced that allows you to add information about the road conditions. If there is a wreck or ice or any kind of danger Austinites are able to mark the spot and let everyone know what is wrong with that part of the road.
Has anyone checked out this website? And can you see all of the RED symbols? That is a LOT of warnings….
You can check it out here: Austin
