1834 Sharon Mills/Ford Village Factory on River Raisin upstream of Manchester, MI

Street View, May 2023

This appears to be an exhibit about water power. On the left is a water wheel, in the middle is a Francis turbine and on the right is a Pelton wheel. The Francis turbine made the water wheel obsolete because it was more efficient. The Pelton wheel is used for high head, low flow dams. That is, the water has to be under high pressure.

Henry Ford's Hidden Power Plant

"Henry Ford virtually invented the GIANT factory, but at the same time, he evangelized tiny, water-powered micro-factories, which he called his Village Industries, and some of them still exist!

"Join me at Sharon Mills, Henry Ford's 13th Village Industries site, which started out as an 1834 Muley sawmill, then a grist mill, before turning into a water-powered auto parts factory in 1928 with the installation of a Francis water turbine.  Today, it's home to the last, working, hydroelectric power plant for these Village Industry sites."

This village factory made cigar lighters and electrical switches.

I'm back. (I'm done for now because of a Google bug)

About 2:30pm on Sep 9, 2026, when I tried adding a photo to a post, it did not work. Blogger did the upload, but the photo never appeared in the post. I tried some things to work around the problem such as a different post, a different photo, deleting an existing photo in case I was at some unknown limit, a different browser, waiting a few hours, waiting several hours, etc. Nothing worked. So, I'm giving up for now. I'll do a test each day to see if the photo upload got fixed. When fixed, I'll resume posting.

Update: within 24 hours they fixed the bug. That bug was so bad that they had to fix it. It confirmed my theory that Google doesn't test new versions of their blog software.

Miami & Erie Canal Lock #15, Canal Boat and Roller Mill in Tipp City, OH

Miami & Erie Canal Overview

A lock means there is a grade separation of water so a mill next to it makes sense.

Street View, Oct 2016

4 of 8 photos posted by Tim Snyder with the comment: "Visited two locks from the Miami and Erie Canal. The first four photos are from Canal Lock Park in Huber Heights, OH. Sadly, the park has no historical markers for the casual visitor. The next four are from Canal Lock Park in Tipp City, OH, which did indeed have a historical marker that identified the lock as Lock Number 15 on the Miami and Erie Canal. Adjacent to the lock is what appears to be replica canal packet boat in need of maintenance."

Vivian Davis: Canal boat in Tipp is not a replica

Randy Westfall: In Miami co there are still lock 16 which is on private property

The canal boat is behind the mill, and it appears they already did a lot of restoration work.

Schenley Bridge is a similar arch bridge that is a few blocks north of this one.

Postcard via BridgeHutner

"Significance: Schenley Park Bridge over Panther Hollow includes design elements from the City Beautiful movement while utilizing Pittsburgh's "native" industry: steel. An elegant three-hinged steel arch, the bridge is a contributing structure to Phipps Conservatory and the Schenley Park Historic District, both listed in the National Register of Historic Places. " [HAER_data]

This 640' (195m) long bridge has a main span of 260' (110m).
"This bridge is a very old and large example of steel arch technology, and is also a rare example of a three-hinged deck arch. Just as noteworthy are the bridge's stone arch approach spans. These feature the rare elliptical shape of stone arch."

A close up of the elliptical stone arches.

Steel City History posted
PITTSBURGH, THEN AND NOW 🌉 This is the Panther Hollow Bridge in Schenley Park, photographed in the early 1900s spanning the wooded ravine near what's now Carnegie Mellon University. Fast forward to today: the bridge just reopened to vehicle traffic after being closed since October 2024 for safety repairs. Same span, same hollow, generations of Pittsburghers crossing it.

This c. 1900 photo shows Schenley Park's Panther Hollow Bridge, built in 1896 to blend City Beautiful design with Pittsburgh's own signature material: steel. The bridge still carries visitors across the ravine near Phipps Conservatory today.

2012 photo by Joseph via BridgeHunter

"The 'Panthers' by Giuseppe Moretti (1859-1935) provide the signature which easily distinguishes the pair of structures. A bronze mountain lion stands ready for the hunt at each corner of the Panther Hollow Bridge." [pghbridges]

1928,1999-2018 Kanawha Falls Bridge over Kanawha River near Kanawha Falls, WV

(Bridge Hunter; Historic Bridges; Satellite)

Street View, Jun 2021

Southern West Virginia Online posted four photos with the comment:

The Kanawha Falls Bridge has now been closed for nearly eight years…

The bridge was shut down in November 2018 after a structural failure caused part of the bridge deck to drop about five inches. Inspections later uncovered additional deterioration and structural concerns. 

Today, the nearly century-old bridge across the Kanawha River remains closed to traffic.
