CSX/PM Abt Trunnion over Saginaw River in Saginaw, MI

(Bridge Hunter, Historic Bridges) Dan Shankel posted five pictures with the comment: "One of my favorite local bridges in Saginaw, Mi"

I include the first one because it is on an angle and best shows the trusses and the second one because it includes the tower.

Since the only other bridge in town is a swing bridge, it was easy to find on Google. Fortunately, the 3D option worked pretty well on this bridge. Compare this bridge to the PM Bridge in Port Huron to see how the counterweight goes down while the machine room goes back down the diagonal rack.

Birds-Eye View, note the image is older because it still has the tower
