Can you guess the year this photo was taken, and where exactly this mystery ramp was located? As usual, we'll update later with the answers and more details.

UPDATE, 4:45 p.m.: This photo, provided by the Municipal Archives, was taken on November 6th, 1930. It shows a "temporary ramp" as seen from 23rd Street. This was for the West Side Elevated Highway, and the temporary ramp was in place because construction between 22nd and 38th Street was just set to begin in 1931.
