Astoria Park Field House and running track. I can't find specific references to these anywhere, but we do know the Parks Department built this park in with New Deal funds and labor as part of the Triborough Bridge project, and now (July 2017) we have a 1937 photo that shows the same track and fieldhouse at the Queens end of the Triborough Bridge: CLICK HERE to see it, then click the Enlarge button and look at the lower right edge of the image.
