About a year ago, someone painted a yellow line on this curb ramp, on a mostly residential street that abuts a park. “It’s the only sidewalk ramp on that side of the street for a block in either direction,” says our reader, “so when someone blocks it, if you need a ramp to access the sidewalk (or the park), you have to go a block out of the way.” According to our tipster, who walks by the ramp twice a day on weekdays, drivers are now much less likely to block it.
