At least, that's what the street marking on Fairmount Avenue Southwest says. Over the weekend, Seattle Department of Transportation (SDOT) employees applied roadway markings in eight locations, reports the Seattle Times. In the West Seattle location, employees marked the street "20 HPM" instead of "20 MPH." 20 hours per mile would make the speed limit .05 miles per hour – half the speed of the world’s slowest mammal, the three-toed sloth. SDOT is in the process of correcting these markings and will complete the work today (unless they work really slowly).
.05 miles per hour?
