B&SV/C&NW Bass Point High Bridge near Boone, IA

(Bridge Hunter; no Historic Bridges; Satellite)

I was going to skip yet another steel tower trestle. But when I saw that the public can ride on this trestle, I decided it was worth noting.

Chris Ciesla posted six photos with the comment:
Bass Point High Bridge sit NW of Boone, Iowa and was originally built by the Fort Dodge, Des Moines & Southern, an electric interurban that ran from Des Moines to Fort Dodge and Rockwell City, Iowa.
It's still possible to ride over this bridge on the Boone & Scenic Valley RR who purchased the ;one from the C&NW in the 1960s to continue operate this section of the RR.

[I wonder why Dave thinks this one is greater than the Kate Shelley Trestle just a mile or so southwest from here.]




[This trestle is an example of the design that saves steel by using deeper girders between the towers than over the top of the towers.]


A topo map shows that the Des Moines River has carved a bit of a canyon in this part of Iowa. Thus the tributaries such as Bass Point Creek also have a canyon. On this 1965 map, the railroad is still labeled Fort Dodge, Des Moines & Southern. So the C&NW was reluctant to purchase an interurban.
