1844-73 Erie Extension (Beaver and Erie) Canal Overview and Lock #10

This canal connected Lake Erie with the Ohio River in western Pennsylvania. I knew of two canals in Ohio (Miami & Erie and Ohio & Erie) and one in Indiana (Wabash & Erie) between Lake Erie and the Ohio River, but I did not know of this one. I learned of this canal while researching the Shenango Dam.

The canal cut the travel time for passengers between Erie and Pittsburgh to 36 hours. [0:26 video @ 0:08]

See Girard Lock for the southernmost lock.

It was finished in 1841. [0:26 video @ 0:08]
It was finished in 1844. (All the other sources that I read agree with 1844.) The canal was built North from Beaver to Erie. It needed 137 locks. [ErieHistory]
It was 136 miles long. The 137 locks handled an elevation difference of 977' (300m). The 91 mile (146km) east/west Pennsylvania & Ohio Canal connected this canal at New Castle, PA, with the Ohio & Erie Canal. [blogspot]

"At Sharpsville, Pennsylvania,  lock #10, the only remaining lock, now has a walking trail through it."
[This explains why I could not find it in a satellite image, it is obviously covered by a tree canopy. I think it is along the Trout Island Trail.]

"In 1873, the destruction of an aqueduct across Elk Creek Gorge which had allowed canal boats to cross the deep river gorge spelled the end of the Erie Extension Canal. Some believed that railroad designers had deliberately caused its destruction. Railroads were becoming the preferred transportation of the period; the canal beds provided the perfect basis for the railroad bed." [memory]

The aqueduct was 500' (152m) long and 100' (30m) above the creek. This source put the collapse in Sep 1871. [blogspot]

Given this map, the aqueduct was here.

The Canal Museum in Greenville, PA, is at the location of Lock #22. (Greenville also has a railroad museum.)

Update:
Anita Breitweiser Chase Palmer posted ten photos with the comment:
In 1834, construction began on the Erie Extension Canal’s Beaver Division or the southern part of the canal.
The southern ending of the canal was the confluence of the Beaver River with the Ohio River in Beaver County, about 20 miles downstream from Pittsburgh; and the northern ending was in Erie county, ending at the foot of Sassafras Street in the city of Erie. The canal needed a total of 137 locks to overcome a change in elevation of 977 feet.
In the early 19th century, the Erie Extension canal system was a 136-mile-long waterway that connected Lake Erie to the Ohio River and Pittsburgh, it was sometimes used by enslaved people to escape from southern plantations. The Erie Canal Extension ran through the center of Girard, PA beginning around 1840,
German immigrants, who were paid $8 a month, and three jiggers of whiskey a day, dug a canal that was 60 feet wide and 10 feet deep. The primary challenge was in overcoming an elevation change of about 1,000 feet over the entire 136-mile stretch from the Ohio River to Lake Erie. The canal’s elevation was accomplished through the placement of 137 locks, 72 of which sat between Erie and Conneaut Lake. There were 28 locks alone in a two-mile stretch of canal through what is now Platea.
Regular travel began in the spring of 1845, opening a faster and more-workable form of transportation. The canal gave travelers a direct north-south route to connect with railroads that largely traveled east and west at the time. A trip from Erie to Pittsburgh that once took days by wagon or horseback, over rough country roads and Indian trails, could now be done in 36 hours by packet boat for $4. The new mode of travel helped boost the region's population and brought in some notable people, they included famed performer Dan Rice who rode the canal into Girard in the 1850s to set up winter quarters for his circus and to use the transportation system to travel south.
Eventually the Railroad was seen to be more efficient. It was cheaper to build and you could lay tracks almost anywhere. It wasn’t depended on the weather to have an adequate water level, like a canal system, and you could lay tracks way beyond the reach of any canal system.

The official end came in September 1871, when a 500-foot-long aqueduct that carried canalboats 100 feet above the Elk Creek gorge near Girard caved in. Some blamed it on lack of maintenance; while others suspected that people who had an interest in the railroad helped it fail.

The canal is remembered today, mostly by 12 roadside historical markers, all dedicated by the state in 1948 that marks various points in Erie and Crawford counties where the canal or its feeder systems were located.. the former canal bed remains visible in some areas to this day.

Digger Mincer: There is a canal museum in Greenville, Pa by riverside park. The canal ran through Greenville. You can check it out on on the web.
Gary Dufford: Our local canal extension was in use until 1919 when the big flood when all the dams were destroyed. As far as I know the barges just carried coal from the mines to the coke facilities up and down the river.

Detroit, Toledo, & Ironton [DT&I] tressel in downtown Washington Court House, Ohio, heading south for Wavery and Jackson. It now sits as an ornament on the city walking/cycling trail.
Troy Kleman: Henry Ford's railroad. The DT&I turned quite a profit under Ford's ownership.
Mike Kotler: My understanding is that the DT&I route via Waverly was abandoned because of a treacherous, sharp curve on the line that was notorious for derailments. They got trackage rights on a parallel route instead.
Tim Shanahan shared

The B&O had two routes through town, and the Pennsy also had a route through town.

The DT&I route north of  Washington Court House (WCH) is now owned by the Indiana & Ohio Railway (IORY). And the remaining B&O routes are also owned by IORY.

The DT&I and B&O paralleled each other between here and WCH. The IORY now uses the B&O route on this segment and the DT&I tracks are sometimes used for storage. Because the IORY uses the B&O route, the DT&I upstream crossing of the river is also abandoned. But we can still see the footings of the DT&I bridge.

The former-B&O bridges are also trestles.

Shenango Intake Dam Rehabilitation
To rehabilitate the Shenango Dam, Great Lakes had to install a cofferdam which would allow work to be performed while diverting the river water around the construction area. After the water was diverted, Great Lakes performed concrete repairs, a new sheet pile cut off wall, relocated the 24” waterline, and grouted rip rap.

USACE, Pittsburgh District posted four photos with the comment:
Have you ever spent a snowy winter day cozied up at home, enjoying a hot cup of cocoa/tea/beverage of choice, foregoing subzero temperatures in favor of a comfy blanket, and thought to yourself:
"If only I could ditch this junk and go sleep in a tent at a Shenango River Lake Old Duck Loop campsite."
Well, friend, we've got great news for you! 
Campsites in the Old Duck Loop campsites are now open year-round!
Details:
- Old Duck Loop campsites (192-225) now stay open all year
- Electric hookups, dump station, and shower house available (though visitors are encouraged to bring a generator)
- Reservations available at 👉 Recreation.gov 
Winter camping isn’t for everyone…but for the bold, the adventurous, or just the people who think hot chocolate tastes better next to a frosty tent flap - Old Duck Loop is waiting. 🦆

2013 1380m (4528') Hardangerbrua (Hardanger) Suspension Bridge in Norway

(Satellite, 1,196 photos)

VisitNorway
"The main span is 1380 meters [4528', 0.85 miles], the towers are 202 meters [660'] high, clearance below is 55 meters [180']."

At first I was confused because 1380m was used for both the length of the bridge and of the main span. Then I noticed that both ends go into mountains and the cables are anchored on the mountain. It amazes me how simply tapering the top of the towers makes it look so much more elegant. Yet it did not cost much to do that. I wish American civil engineers would learn that aesthetics need not be expensive.
(Actually, the main span is "only" 1310m. [ntnu])

Construction started in 2009 and it officially opened on Aug 17, 2013.

This is another example of other countries putting more value on non-vehicular traffic than does America. About a third of the used space is dedicated to non-vehicular traffic.

Norway Sky bridge Construction
The Marine Buff posted
The construction of the Norway Sky Bridge involves the use of ships to transport and position the massive steel pontoons and other structural components. These ships play a crucial role in delivering the prefabricated sections to the construction site on the fjord. The pontoons are anchored to the fjord bed using mooring systems that are installed and adjusted by specialized vessels. Additionally, crane ships are used to lift and place the heavy steel sections and other materials into position, ensuring precise alignment and secure assembly of the bridge's structure.
[As a comment pointed out, this is not the method that was used for this bridge.]
This method allows for efficient and accurate construction over deep water where traditional methods of building piers are not feasible.
The Marine Buff posted again
The construction of the Hardanger Bridge, Norway’s longest suspension bridge, began in 2009 and was completed in August 2013. The project was overseen by the Norwegian Public Roads Administration, with MT Højgaard responsible for steelwork and assembly. The bridge has a total length of 1,380 meters, with a main span of 1,310 meters, making it one of the longest suspension bridges in the world.
The structure includes two 200-meter-high concrete towers and two suspension cables, each made up of 10,032 wires with a combined weight of 6,400 tonnes. The steel deck was built using 23 pre-fabricated sections, each weighing 400 tonnes. These sections were assembled on-site and lifted into place using specialized cranes.
In addition to its two traffic lanes, the bridge also accommodates pedestrians and cyclists with a dedicated path, reducing travel time between Oslo and Bergen significantly by replacing a ferry route across Hardangerfjord.

You drive out of a rock face right onto the bridge. It’s pretty impressive, especially the first time when not expecting it at all.

This was an interesting tidbit I discovered in a result documenting that this Norway bridge is longer than any suspension bridge in the USA.

Trail/Milwaukee Bridge over Chippewa River near Durand, WI

(Bridge Hunter broke Mar 22, 2023; Historic Bridges; Satellite)

Bob Smrtz posted
Old Milwaukee Road bridge crossing the Chippewa River near Durand Wisconsin. This branch line ran between Red Cedar and Menominee Wi and was abandoned in 1973. It is now a hiking/ biking trail.
Tim Schneider: I believe this bridge was moved from the main line at spring green,wi
Bob Smrtz: Tim Schneider yes, it looks like part of it was. Reading the history that Coroi Alexandru Mihai posted it looks like all 3 spans originally came from different locations and were reused here. Very interesting.
Scott Rogers: Yes, this is the Red Cedar State Trail. This is just north of the junction with ex-MILW Chippewa River State Trail that runs from Durand to Eau Claire. There are also 2 former Milwaukee Road bridges within the City of Eau Claire that are also bike/pedestrian trails.

Jordan Palmer posted seven photos with the comment: "Truss/trestle bridge over the Chippewa River in the Dunnville Bottoms, part of Milwaukee Road’s line to Menomonie, WI. Just south of the bridge the branch connected to the line up to Eau Claire, the two branches were part of the Chippewa Valley Line. Following failure to try and keep the line alive once it entered state ownership both routes were converted to trail use. My photos from fall of 2024."
Greg Bunce: The large truss was moved from Iron Mountain, MI where it crossed the Menominee River. It was replaced by another bridge in 1902. It was common for railroads to reuse bridges by replacing lighter bridges with heavier bridges and sending the replaced bridge to a branch line.
