The speed bumps on 3rd St S between 22nd Ave S and 17th Ave S are improperly shaped and horrible to drive over. I've driven over speed bumps all over the city without issue, but these two bumps in particular are very destructive to a vehicle's suspension and undercarriage, and are unlike any other bump in the city. The second problem with them is that they are difficult to see at night in this low light area; the signs beside them are inadequate in warning drivers. I have no issue at all with traffic calming in this area and encourage the speed bumps' presence, it's simply the design of these humps that are a problem. Please correct.
