This street is used for transportation from one end of sunset to get to the other. This street replaces 37th ave, and it starts from Lake Merced, all the way down. It is pretty much automobiles that go down the two parallel streets, which go in opposite directions. There are traffic lights that control the traffic. Be warned though, because there has been a history of traffic accidents. The cars go at about 30-35 miles an hour. There is no direct connection between the parallel streets, you have to make a right turn, go down to the next street, and then turn left left to go to the other street going in the opposite drection.
