On 9th northbound, just south of Market, in the 2nd lane from the left, is a surprisingly bad gouge out of the roadway. Each time I hit it, it's a solid jar to the car that seems heavy enough to damage the tire rims. It looks like some sort of half foot wide slot someone cut out of the road bed with a concrete cutter, and never bothered to patch over. Seems to go at least the width of the lane, if not several.
It's big enough that it feels like it's doing damage to my car every time I drive over it.
