Bridges & Tunnels by Sherman Cahal posted four photos with the comment:

This is Tunnel No. 5 of the Baltimore & Ohio Railroad’s Wheeling-Pittsburgh Subdivision. Completed in 1857 for the Hempfield Railroad, it remained in active railroad service until 1985, when the Baltimore & Ohio Railroad sought to abandon the line because of declining freight, particularly coal traffic.

A portion of the former rail corridor has since been converted into a rail trail west of the tunnel. However, the reuse of Tunnel Nos. 4 and 5 has been delayed by falling brickwork in one tunnel and an unresolved dispute with a private landowner.

While looking for the tunnel, I noticed the "Old National Pike." Sure enough, US-40 and I-70 go through here. US-40 Overview

1905-2008 Suspension

This bridge was destroyed by a flash flood on Jun 8, 2008.

I wonder when the additional bracing was added. Note that every third suspender was rigid pipes with diagonal bracing instead of cables. I presume this was done to reduce lateral sway in the deck. I can imagine that the thin deck originally moved too much for pedestrian comfort.

The replacement was opened on Oct 25, 2010. The replacement has trusses to stiffen the deck.

Evidently, it was built for an interurban.

In addition to trestles and tunnels, the Milwaukee had to build a lot of cuts and fills.

1913 (CM+BNSF)/Milwaukee Judith and Indian Creek Trestles between Lewiston and Denton, MT

Judith Trestle: (Archived Bridge Hutner; Bridge Hunter; no Historic Bridges; Satellite)

Indian Creek Trestle: (Archived Bridge Hutner; Bridge Hunter; no Historic Bridges; Satellite)

CM = Central Montana

By 1913, between Lewiston and Danvers, MT, Milwaukee built the Judith Trestle, Indian Creek Trestle, Sage Creek Trestle and Sage Creek (Hoosac) Tunnel.  That route is now operated by Central Montana Rail. The route is also used by the Charlie Russell Chew-Choo. The Dinner Train features western entertainment including a staged train robbery. They also operate a North Pole Adventure Train.

CM/Milwaukee Judith Trestle

"The first trestle the train goes over is the Judith River Trestle. This 33-span bridge is 138 feet [42m] high and 1,953 feet [595m] long. The trestle was severely damaged in the spring of 2011 and was approved for a five million dollar grant for repair which took place in 2014." [MontanaCowboyFame]

CM/Milwaukee Indian Creek Trestle

"Indian Creek Trestle, the second trestle on the Charlie Russell Chew Choo, is a 22-span bridge that is 150 feet [46m] high and 1,303 feet [397m] long. It may be seen just off the Danvers gravel road." [MontanaCowboyFame]

The Indian Creek Trestle was originally part of the route constructed by the Chicago, Milwaukee, St. Paul and Pacific Railroad during its expansion across Montana in the early 1900s. This line required numerous major bridges and trestles to cross the deep coulees and river valleys of the Judith Basin region. This trestle is located in the rugged coulee country west of Lewistown in Fergus County. It carries the former Milwaukee Road line, now operated by the Central Montana Rail, across a deep drainage carved by Indian Creek. At 1303 feet long, it was built in 1912-1913. The line remains one of the few surviving segments of Milwaukee Road trackage in Montana still carrying freight traffic today. Central Montana Rail continues to serve agricultural customers throughout the Judith Basin.

They are making sure that it will be wide open by the time the sailboat gets to the bridge.

It looks like the bridge is high enough to clear commercial barge traffic.

Boldt installed "two new double-regulated, 2.25 MW Z-Turbines (Saxo-Type) and generators. The upgraded generating units double the output, are more efficient and match site head and flow conditions. " [boldt]

Given the horizontal shafts, this would have been the old equipment.

The image in the lower-right corner of this collage is the bottom of a Francis turbine. But all of the other photos I saw in the Google search results were of a Kaplan (propeller) turbine. So, someone must have grabbed the wrong photo when making the collage.

A source stated that the "Saxo" name comes from the discharge tube looking like a saxophone.
