Genesee Aqueduct, 1897 and 2025
The Erie Canal’s second aqueduct over the Genesee River was constructed in 1836-1842. In 1927 the canal bed in downtown Rochester was converted to a subway system, and a road for automobile traffic was build on top of the aqueduct. This structure became what we now call the Broad Street Bridge.
The subway system was abandoned in 1956.

[Several comments mentioned that downtown Rochester is now "dead." No people is one thing, but no cars is hard to imagine.]

As mentioned, the canal was moved south of town in 1919, and it now crosses the river here. I fired up the time machine to see where the canal used to cross the river.

The Lake Washington Ship Canal and this bridge opened in 1917.
The high-level Aurora Bridge opened in 1932 to relieve traffic congestion at this bridge.

Boat View, Mar 2016

I recognize the trusses as a Second Generation Chicago Style Trunnion Bridge. The high-level Aurora Bridge on the right opened in 1932. It was built to relieve traffic congestion because this bridge had to be raised so many times. (The Chicago-based design is confirmed in HisotryLink_bridge.)

IHB Gary & Western LCL Transfer Yard

(Satellite)

Korry Shepard posted
The entry to the former Indiana Harbor Belt Gary & Western LCL transfer yard at Ivanhoe Junction (CP Ivanhoe). I'm looking east while an eastbound Canadian National freight crosses the diamond ahead. Loving the old Griswold signal tower. It still works.

I looked for, and found, the above posting after I saw this posting.
Korry Shepard posted four images with the comment:
I got a lot of questions about the Gibson Transfer Yard, the LCL yard, so here we go.
An LCL or Less-than-Container-Load yard is a space railroads use to hold cargo for multiple customers that does not fill an entire railcar or container. 
What did they do? LCL operations consisted of truck shipments and packages from shippers, as well as their deliveries to the LCL yard. At the yard, clerks consolidated clearance and shipping documentation, resulting in cargo being loaded into railcars until the cars were full. Each railcar carried cargo for multiple customers traveling in the same general direction. Once loaded, workers sorted and placed goods on new trains for distribution to various customers or to a single location. This was commonly seen as more cost-effective from the shipper's perspective, as they only paid for a percentage of the volume they required for any given freight car. In other cases, shippers would share the cost of volume with one or more businesses.
Railcars were spotted on set tracks designated for particular destinations every day. If a LCL load arrived by train or a shipment arrived by truck, the company knew exactly where shipments would go once they arrived at the yard. 
Let's say multiple trucks brought a shipment of barley destined for delivery to a brewery in Gary. At the LCL yard, that specific cargo would always be spotted on, say, "track 7". There could be 13 half-filled barley cars on track 7 that could be filled with the new shipment. Or, shipments can be broken into different "spots" on "Track 7." Say Brand X barely would be spotted on Track 7 at the 5th spot, and Brand Y would be spotted at the 12th spot on Track 7, etc. IHB would fill the cars until each was full. Once done, they would be delivered to the brewery, the empties would be brought back, and so on. 
Sometimes the cars delivered would contain barley on one half of the car, and barley slated for another brewery on the other, or any variation thereof. Now replace barley with any deliverable commodity. Coal, gravel, barley, rye, ore,  stone slabs, or wet goods such as milk, petroleum, water, rubber, etc. If they were local-bound, they were likely sorted in the LCL.
Sometimes, freight arriving at the central Gibson Yard would need to be unloaded into different cars at the LCL Yard. If a shipment of fish came into Gibson from, let's say, Blue Island, and that fish is destined for the IHB freight office in Gary. This car, or associated cars, would be detached from the initial train and transferred onto a train bound for the LCL yard. Once there, the fish would be transferred to another car spotted on a designated track, and the original car would be returned to Gibson later. Once in Gary, the fish would be unloaded into a truck for distribution.
IHB was not the only laborer in the yard. By the 1940s, much of this work had been contracted to brokers. These brokers hired workers to handle specific freight in the yard on behalf of the cosigner or company. These contracted grunts would load freight into cars owned by their employers. IHB would have rented out spots on certain tracks for these types of workers. This freight would be transported on LCL trains from a specific location. 
Sometimes the destinations were not local, but were set to be transferred to another train for further transportation east of Gary, and IHB was the bridge between. There were also situations when specific freight required the car to be in a different spot on the LCL train multiple times until the car was empty. All of this work was done on precise schedules. Time is money on the railroad. The work was hard, long, tedious, and went 24/7. This was the time when a freight yard clerk position was coveted. They were the ones keeping track of all of this movement and work, without sophisticated software and computers to aid them. Trucks would also come to the yard to pick up shipments.
In the early 1910s, IHB was the only railroad handling LCL operations. The next railroad to enter that game was the Baltimore & Ohio in July of 1912. That same year, in response to a new LCL yard opening at Clearing Yard by then Chicago Union Transfer Railway and the Chicago and Western Indiana Railroad, New York Central announced its intention to build a brand-new LCL yard for IHB near Gibson. The City of Gary had not been touched by any major railroad entity about a new interchange and LCL yards. Kirk Yard and some smaller yards in its orbit were about the extent of this business. It was so new that its population didn't justify the cost of scraping out new rail yards within the city itself, especially for LCL business. The streetcar system was enough to handle Gary's traffic. The new IHB LCL yard, which began construction in 1913, was expected to meet Gary's future business needs, as it was anticipated to grow exponentially over the next decade.
By November 1913, grading was completed at the new Gibson Transfer Yard, and work began on the initial 14 miles of trackage. Numerous freight sheds were built to serve the IHB, Michigan Central, and Michigan Southern railroads. The yard had two units. A gigantic "wye" was constructed west of Kennedy Avenue, which would connect the new LCL yard with the main Gibson Yard, and provide passage for Michigan Central freights to the yard as well. They called this section "Unit 1." Unit 2 was east of Cline Avenue, beginning just west of Ivanhoe Interlocking. By spring, construction had included 32 additional miles of tracks, more office buildings, loading platforms, a two-story boarding house, a cafeteria, and employed 230 workers. 
 In 1917, a large sulphuric acid fire caused by unknown means resulted in the loss of a few miles of track and three smaller platforms. This hastened an additional investment in the LCL yard. It ensured that IHB's LCL Yard was, according to the Times, "the largest and most complete 'less than carload' freight transfer yard in the world." When 1917 rolled around, the LCL yard had a 200-foot-long building with loading platforms. The building had modern electric generators and other conveniences not typically seen in other LCL yards. It wouldn't be until 1924 that the entire yard would be completed, with an additional 30 tracks. Another fire destroyed an office building, destroying many records.
In 1958, New York Central began its new "flexi-van" truck-to-rail piggy-back service at Gibson Transfer Yard. It employed a new technique that allowed flat trailers to slide from the train car to highway wheels in about 4 minutes. When the truck reached its destination, it could slide back onto a railcar and start the process all over again. This was the first instance of this service anywhere in the United States. This service operated between Chicago and New York.
By 1960, there was too much competition with trucks and the further evolution of commercial interstate road systems. LCL freight movements fell rapidly due to trucking. IHB petitioned the Indiana Public Service Commission to discontinue LCL freight service. The petition was granted that June, and service immediately ceased. As the IHB railroaders aged, they lost their positions and subsequently began retiring in large numbers. In 1977, a railroad relocation project nearly saw the Chessie System utilize the Wabash 4th District to access the Gary & Western high line, allowing it to reach the old Gibson Transfer Yard, where it planned to repurpose the abandoned yard. However, this never materialized.
Rick La Fever: At one point, NYC/IHB had a transload service called Flexi-Flo on the site of Gibson Transfer Yard. Flexi_Flo was a series of rounded covered hoppers that I think could loaded and unloaded by air pressure. Since many of them were used for cement service, it would make sense to route some to NW Indiana since we were still building with concrete. USS Atlas Cement used to be at Buffington Harbor but closed in 1991. After that LaFarge unloaded cement at Buffington from barges or boats(remember Great Lakes Ships are commonly known as "boats" no matter how large.)

Here is a close-up of Unit 2, from 1951. IHB Gibson Transfer Yard, LCL. You can see the trucks and other vehicles parked in the yard, along with other yard facilities. I annotated the image.

Korry Shepard commented on his post
Here is the LCL yard from 1983. It had ceased operating as an LCL yard for over 20 years by now.

I have to learn to completely read a posting before I research the topic! Obviously, the yard in question are the two sets of tracks between Kennedy and Cline. What surprised me was the lack of freight houses. Normally, freight houses are the center of operation for LCL freight. But those operations handled package freight in boxcars. According to Korry's description, this facility handled bulk LCL freight. (This map explains the "baseball diamond" looking facility at US-20 & Cline in the above aerial photo. It was a drive-in theater.)

Since I got an aerial looking for freight houses, I'll include it. It appears that I found the same photo. IHB's big Gibson Yard is out-of-frame to the left.

Today, the yard has gone full circle in terms of providing an interface to the "last mile:" transloading. By using IHB's yard, the transload company can service all six Class I railroads.

Welland Canal Bridge 17 - Dain City Railway Bridge (Welland, Ontario)
Historic Dain City Railway Bridge (Welland Canal Bridge 17) in Welland, Ontario, Canada. This section of the canal was bypassed by the Welland Canal Relocation Project (realignment around the city of Welland) in 1973.
The bridge is a Parker through truss vertical lift railroad bridge, although it no longer opens for water traffic. It was built ca. 1927 for the Canada Air-Line Railway (later the Canadian National Railway (CNR)) as part of the 4th Welland Canal expansion project (1913-1932). It is used today to serve local industries only.

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.
