Leon Moisseiff was a consulting engineer for the Triborough bridge but the engineer of design was Allston Dana.
That's the Bronx Kills span, its a special design (based on Warren truss) because it was built as three fixed through truss spans, specially configured for easy future adaptation to a vertical lift design (towers and machinery would have been constructed on the bridge).
Similar provisions were made for the Hell Gate Bridge's Bronx Kills span, except that bridge was intended to be a Strauss bascule rather than a lift. Ultimately the conversions never happened with either bridge.

The opening of this bridge on this date on July 11,1936 was mentioned in the local paper today where I live.
