Shapefiles of roads can be downloaded from the US Census's TIGER database and from local municipalities but what about speed limit data?
Like from point A to point B on a given roadway the speed limit is x mph, while from point B to point C, the speed limit on that same roadway might be y mph.
Is this data available anywhere as a shapefile or anything?
If it's not available on a national level might it be available at various state or local levels?
Data Source for Speed Limits is a similar question but it's from 10 years ago and the answer looks less like a definitive answer and more like a "you can make certain educated guesses based on this ruleset" type of answer.
