Also in this area, the double-yellow line in the middle of Pennsylvania Avenue has an "opening" (meaning a break in the line) at Rimhill Road, presumably for vehicles turning left onto Rimhill. However, this "opening" is badly misaligned with Rimhill. This leads drivers to turn left immediately where the double-yellow ends which results in them cutting the blind corner onto Rimhill, driving over the painted "stop line" on Rimhill and into oncoming traffic.
It is also worth noting that there are no sidewalks on Rimhill Road — pedestrians must walk in the street. Many of these pedestrians are people walking dogs (such as myself) or children playing. Also, the area in front of the dam at the north end of Pennsylvania is popular with skateboarders.
Combine the above with people's habit of driving at excessive speeds in this area, and you have a recipe for tragedy.
