1887-1927 11th Street Elevator (Incline, Funicular) in Dubuque, IA

(Satellite)

The Fenelon Place Elevator still exists.

Street View, Aug 2018

Barbara Lewra posted 10 images with the comment:
The 11th street elevator in Dubuque was a funicular cable car system used to navigate the steep hillside along Bluff Street. (See below for a description of a funicular system.) It operated at Eleventh Street from 1887 to 1927 before being dismantled in 1929. 
This elevator was very similar in design to the 4th Street Elevator that is open to the public and is still in operation today. However, the 11st elevator was never as popular or as successful as the one at 4th Street. As the automobile gained in popularity, the elevator became much less of a daily necessity for the neighborhood, and it was eventually dismantled.
See the captions included in each photo to see how this elevator has changed over the years.
The primary structure remaining of the elevator is a massive limestone wall and tunnel that the elevator cars originally traveled through so horse traffic could cross the tracks on the street above. Today, the rails have been removed but you can still follow a paved path and lots of stairs to follow its path.  There is a small “park“ near the top that has been landscaped and includes a small monument with a brief history lesson. Awaiting you at the park is a bench to sit on and rest from your climb up the steps while enjoying a panoramic view of the city.
Description of funicular street elevator system: This type of elevator, like the 11th and 4th street elevators, consists of two rail cars that always start at opposite ends of a hill and pass each other at the mid-point as they travel up and down the hill. The cars in the cable-driven railway are powered by an electric motor and winch in the station house at the top of the hill. The motor only needs to overcome friction, inertia, and compensate for the varying weight of the passengers in the cars. Because the cars counterbalance each other, the weight of the car going down the hill does much of the work and helps to pull the other car at the bottom up to the top.

US-31 and CSX/GM&O Bridges over Alabama River near Montgomery, AL

A truss bridge was built in 1926 for US-31 over the Alabama River. [Bridge Hunter]
Life in Alabama posted
This was the old bridge, which crossed the Alabama River on Hwy 31, providing access to/from Montgomery and Prattville.  Some of you may remember that it was a very, very narrow two-lane bridge.  I snapped this photo several years ago, shortly before it was demolished.

William Morrison posted with the same description.
Ruth Dennison: It turned in the middle for large boats, also the railroad tracks were next to it, it moved in the middle as well.
[This comment caused me to take a closer look at the photo. The middle pier is round, so that would be holding the swing span.]
Shannon Dean posted with the same description.
[Plagiarism is bad enough. But to explicitly claim that one took a photo that was stolen really hurts my head. A comment challenged that she took the photo. Shannon still claimed she took it. When challenged with the Life in Alabama post, she replied: "It's been taken twice. The one you attached and one other Alabama site." I'm supposed to believe that both photographers got the tree leaves in the same positions? I don't believe that. What I do believe is that Facebook is allowing a lot of false profiles to be built so that they can scam people.]

In 1954 another bridge was built to carry the northbound traffic.

"Blount Brothers Construction Company of Montgomery built the bridge; John C. Bullard, Sr., served as field engineer for the project, and H. H. Brandt served as field superintendent. Todd Shipyards in Houston, Texas, fabricated the girders, which were delivered in sections by rail to Hunter Station, just south of the river. They were then carried by truck to the bridge site and were erected from a temporary wooden trestle that spanned the river. During the assembly, the girders were were spliced together using steel rivets. At the time, the 220-foot steel deck girders for the main span of the bridge were the longest the Alabama State Highway Department had ever designed and built."

"This 1954 photo shows workers assembling girders during construction of the bridge over the Alabama River for the northbound lanes of U.S. Route 31 between Montgomery and Prattville. Blount Brothers Construction Co. of Montgomery built the bridge. A shipyard in Houston, Texas, fabricated the girders, which were delivered in sections by rail. At the time, the 220-foot steel deck girders were the longest the Alabama State Highway Department had designed and used." (Photo courtesy of the Alabama Department of Archives & History)

Jake DeCourcey: Notice the climbing wrenches.
Cos Cob Bob: This picture has a lot to look at. I like the bowstring to stabilize the top flange. [Until they attach a plate as the top flange.]

Dave Frieder commented on the above post
That is called a Plate Girder. One of the Floor beams for the GWB. 118 feet long, 10 feet high, top and bottom flange is 2 feet wide. Weighs in at 62.5 Tons.

The truss bridge was replaced in 2001. [Bridge Hunter]
I'm really surprised that I could not find HAER information on the truss bridge.
That is a strange pier design. Steel has gotten stronger. Those girders don't look as deep as the 1954 girders. Note the railroad bridge in the background.

Speaking of the railroad bridge.
Note the round pier on the left. The swing span has been replaced by a couple of steel-girder spans. And the other side of the bridge is now a lift span.

The CSX route is a former GM&O route.

ICG dumped a lot of the GM&O routes, so I researched who got this route because a satellite map shows that the track has new ballast. What blows my mind is that the owner changes between Prattville and the bridge.

The Gilpins Falls Covered Bridge is a Burr arch truss bridge near North East in Cecil County, Maryland. The bridge structure has a double-Burr arch truss. The bridge was originally constructed in 1860, and then restored in 1959 and 2010. It is listed on the National Register of Historic Places. A modern bridge has been constructed directly adjacent, so the bridge has been closed to traffic. However, it is preserved, with a small parking lot just off of Route 272 less than a mile from an exit on Interstate 95. Because it is so close to the main highway, and prominently visible to passing traffic, it gets a large number of tourist visits.

Road and Railroad Bridges over Kennebec River in Norridgewock, ME

1928 Road: (Archived Bridge Hunter; Bridge Hunter)
2011 Road: (Archived Bridge Hunter; no Bridge Hunter; Satellite)

According to a 1956 topo map, the railroad route was owned by Maine Central. ArchivedBridgeHunter_c1921 indicates that it is now owned by Springfield Terminal Railway (ST).

The three piers with vegetation growing on them would have been for the 1870s truss bridge. The concrete piers would have been added for the c1921 bridge because the steel-girder spans are shorter.

What surprised me is that the deck can evidently hold itself up without the arch.

I traced the Niagara Escarpment from a known location, Decew Falls, to here. The green (tree) line above Sherman Access Road in the lower-right corner is part of the escarpment. The roads slant across the green line to provide a reasonable grade for traffic. So the high ground at the high bridge must be another manifestation of the hard cap rock.

Given those steel tie rods, I wonder when this bridge was built. I've seen a lot better replicas.

Trail/Katy Tunnel and Moniteau Creek Bridge at Rocheport, MO

Tunnel: (Satellite)

The town as preserved the Katy depot as its city hall.

In the center of the bridge, through the railing, you can see the plate girders of the main span.
Rose Hewitt, Oct 2022

Alex Thomas posted four photos with the comment:
BUILDING A RAILROAD TUNNEL AT ROCHEPORT MO, CIRCA 1890
The Missouri, Kansas & Texas Railway network—the KATY Lines—completed a tunnel at Rocheport, Mo., in 1892, beside the Missouri River.
Today the tunnel remains as a feature of the Katy Trail State Park across Missouri, for hiking and bicycling.
"Located in Rocheport, this short tunnel carries the Katy Trail under Moniteau Bluff ... a 243-foot structure, blasted through rock," reports John Marvig, photographer/preservationist of railroad bridges in America.
"Work for the tunnel was contracted to the R.P. McCormick & Company of Kansas City, Missouri. The structure was originally intended to be 440-feet long, but was shortened due to the nature of the bluff."
"The walls of the tunnel are lined with cut stone, and brick has been added to portions of the ceiling at the west end to stabilize the tunnel. This tunnel is the only tunnel along the Katy Trail."

It looks like there is a truss bridge still left somewhere on the Katy Trail.
