This is where I got the name Typewriter Bridge for the above bridge that was next to Remington Arms. I think this bridge carried today's Catherine Street.

The lock was dismantled in 1936.

I could not find the lock on this map nor on a 1900 map. The next map available is 1943, and the canal no longer exists.

(Archived Bridge Hunter; Bridge Hunter; no Historic Bridges; Satellite)

Brian Jules posted seven photos with the comment: "Sunbury, Ohio with the repurposed railroad trestle of the Ohio and Erie trail. This railroad  trestle collapsed in 1886 and again in 1910! Finally made right with an iron span in 1910. Trestle spans Big Walnut Creek, location of a Berea sandstone quarry just to the north. Info referenced from The Berea Sandstone Quarries of Ohio, Ralph Pfingsten. Historical photos Big Walnut Creek Historical Society."

"The Ohio to Erie Trail is a dedicated multi-use trail crossing Ohio from southwest to northeast, stretching over 326 miles of regional parks, nature preserves, and rural woodland. With the completion of this new Sunbury Trail section, the trail is roughly 85% complete. The trail, named after its endpoints, extends from the Ohio River at Cincinnati to Lake Erie at Cleveland, integrating former rail trails and multi-use trails into a dedicated route​​."

It looks like they maintain their truss bridge.

Some docks and walkways are under water, but a good power wash should restore them.

"In 1894, the Town of Bracebridge established itself as the first municipality in Canada to own and operate a water-power electrical generating station." This was called Bird's Mill and produced 84kw.
"A second turbine was added that pumped water up a main street watermain."
In 1902, a 300kw unit was installed, and second 300kw unit was installed in 1905.

The 600kw station had a head of 10m (33'). "In 2012 the facility completed a series of upgrades, which have expanded the facility’s capacity to 2.6 MW.  Upgrades to the facility involved modifications to the existing powerhouse, turbine and generator replacement, installation of a new penstock, electrical system upgrades and deepening of both the intake and tailrace channels.With significant technology advances in the past century, the renovated facility now boasts one (1) Norcan S-Type Hydraulic Turbine as well as one (1) SAB Horizon Brushless Synchronous Generator, which are controlled by a Rockwell Automation ControlLogix system." [OntarioRiversAlliance]

The 2012 upgrade replaced all of the power generation equipment without damaging the existing buildings, "all while working in close proximity to a pristine water environment with stringent environmental protection measures and fish habitat protection." The flow was increased from 10m3 to 27m3 (353cfs to 953cfs).

Somewhere I saw that the upgrade cost $11m. but now I can't find that reference.

2008 US-50 Blennerhassett Island Bridge over Ohio River near Belpre, OH

The Blennerhassett Island Bridge carries U.S. 50 over the Ohio River and Blennerhassett Island between Belpre Township OH and Washington WV... just outside of Parkersburg, West Virginia. Pretty neat bridge. (I took this photo in April 2021 while I was passing through the area.)

"This is a network arch bridge- similar to a modern tied arch but more in common with a historic Bowstring truss with its diagonal hangers. Acts more like a truss than a tied arch under analysis." [Ian Anderson comment on ArchivedBridgeHunter]

"You mentioned the contractor, Walsh Construction, and to be complete, the designer, a joint design by Michael Baker Corporation and HNTB. I was the project manager for the design of the main span and plate girder approach spans and enjoyed the challenge of design of the second network tied arch on the North American Continent. The only other networked tied arch, currently, is on Interstate 195 in Rhode Island. The owner of the Blennerhassett bridge is the West Virginia Department of Transportation. It is now, according to my best information, the second longest networked tied arch bridge in the world. The longest was constructed in China just a few years previous to the opening of this structure although I have not personally been able to verify this information."

It is nice to see that a truss bridge is being maintained.

I&M Canal Feeder Canal from Fox River in Ottawa, IL

(Satellite, this is where the feeder canal joined the east/west main canal.)


While studying the I&M Canal Aqueduct over the Fox River, I discovered this feeder canal on this map. In the upper-right corner, the canal originates at the Fox river. Today's N 2959th Rd reuses the eastern part of the feeder's right-of-way. It looks like there were rapids just downstream for the canal's origin.
1915/15 Ottawa Quad @ 62,500

I was surprised to see the feeder canal continue South from the main canal. It was not needed to get rid of flood waters because the aqueduct about a mile to the east could spill excess water directly into the Fox River. Then I saw it labeled a lateral canal on a map. I think that means that it was a spur that was built to encourage more commercial development along the canal in the town. I don't see any locks in the south end of the lateral canal, so the connection to the river must have been to provide a flow in the lateral canal rather than to allow a connection with the river.

The lateral canal explains why the town has a Canal Street as well as a Canal Avenue. Today's Fulton Street reused the lateral canal's land.

1926 52mw Lake Lynn Dam on Cheat River near Cheat-Lake, WV

(Satellite)

Jackson-Township historical preservation posted
Lake Lynn Dam located on the Cheat River just below Point Marion, Fayette County in 1967.
Roy Patton: 90 percent of the lake it impounds is in West Virginia. Cheat Lake. The dam is upstream from Point Marion, not downstream. Downstream would be the Mon River since the Cheat River meets the Mon River at Point Marion, why it’s called a point.

JUST CHILL BY ZAZA , Aug 2024

Judging by the water downstream of the powerhouse, only half of the units are running.
Malenky, Apr 2023

Here, it looks like just 1 of 4 units are running.

This saves me from having to Google this dam. It is nice that the owners provided the basic facts.
