Commuter/NYC Bridges over Harlem River in New York City

1867 Bridge: (Bridge Hunter, drawbridge)
1896 Bridge: (Bridge Hunter, 4-track swing bridge) (The only other 4-track swing bridge I have seen is still in Conneaut, OH.)
1954 Bridge: (Bridge Hunter, twin 2-track lift; 3D Satellite)

This is on the train route that leads to Grand Central Station.

1867 Drawbridge


Since there is no counterweight, this is not a bascule bridge. It is an old fashion drawbridge like the ones that used to be used over the moat of a castle. The steam engine had to be strong enough to lift the full weight of the bridge.
December 1892 Scientific American.

1896 4-track Swing Bridge

[We can tell by the smoke coming out of the smokestack on the left side of the bridge that it was still steam driven when this photo was taken.]
1896 Bridge Hunter
eBook, p246
[The men repairing a pin connection in 1916-17 provide scale for the size of the steel beams. The bridge carried "some 700 train or engine movements per day."]

1954 Lift Bridge

John-Paul Fiorentino Speaking of, the bridge is scheduled to open up at 1030am.
James Teehen They don’t raise that bridge often.
John-Paul Fiorentino James Teehen they did last week and then today at 1030. When they opened it last week, there was an issue with 1 span not locking properly.
James Joyce It does open regularly for testing.
Emily Elizabeth Moser James Joyce when it happened last week it was for a boat to go through.
Wayne Koch Nice! It officially opened some time in 1955.
