SF waterfront Islais Creek bridge (0198)

I could find very little documentation on this bridge. The bridge is on Third street over Islais Creek, the bridge is also referred to as the Levon Hapag Nishkian Bridge, but I could find no documentation as to why it is named that or about its design. Though the design of the bridge is simple, it resembles Streamline Moderne architecture (it was built in 1945.) In the foreground are tracks for the Muni T (3rd street) line that were added recently.
