I want to know the answer to the following question:
What is unusual about the traffic between Broadway and Park Avenue South on 17th Street?
All the background I'm provided with is that "On 17th Street (40°44′08″N 73°59′12″W﻿ / ﻿40.735532°N 73.986575°W﻿ / 40.735532; -73.986575), traffic runs one way along the street, from east to west excepting the stretch between Broadway and Park Avenue South, where traffic runs in both directions.". Is that enough to answer the question?
