American/Chicago Shipbuilding Co. along the Calumet River

(Satellite, three slips allowed them to make six ships at a time because they were launched sideways.)
Later, they switched to fewer, but bigger ships. They were built in a dry dock and then floated out.

I-255+US-50 Jefferson Barracks Bridge over Mississippi River near St. Louis

Image
( Bridge Hunter , 3D Satellite ) I don't normally do yet another steel tied-arch bridge, but when you get a view as unique as this, I went for it. This is "reverse railfan." Specifically, it is a photo from a train instead of a train. And at the bottom is some photos of the cantilever truss that it replaced. William A.

CSX/B&O/M&O 1857 "Big Tunnel" near Tunnelton, IN

Image
Big Tunnel: ( Bridge Hunter , indianarrtunnels ) Big Tunnel:  Satellite plus Paint Originally built in 1857 for the Ohio & Mississippi Railroad and since controlled by the B & O, it is now a part of CSX. It was shortened and brick lined in 1898. A 1700 foot companion tunnel known as "Little Tunnel" was 'daylighted' (turned into a cut) in 1899. [Bridge Hunter] It was dug for a 6-foot gauge railroad. [ IndianaRRtunnels ] Two of the several photos posted by Carlton Crasher. Jacob Leukhardt   Should be one train a day Mon-Fri. The J783 local. I believe it runs between Mitchel and somewhere east of North Vernon. I believe it only runs one direction a day so for example, if it goes westbound to Mitchel on Monday, it should go east on Tuesday, then back west Wednesday and so on. Dennis DeBruler   Thanks for contributing photos to Bridge Hunter and for taking photos of B&O's CPL signals . One advantage of CSX not liking this B&O route is that they don'...

New York City water supply

Image
I've noticed that NYC and Los Angeles have to pay a lot for water supply whereas Chicago has to pay a lot for water removal. I knew NYC dammed rivers in the mountains that are north of the city and then used tunnels (aqueducts) to transport the water into the city. What I did not know, until I studied the Cannonsville Dam , is that they also get water from the Delaware River watershed, which is a lot further away. Since I found this overview map, I'm writing this post to record it. Project Description , page 6 from nyc.gov A NY Times article about a leak in the Cannonsville Dam focuses on the people aspect of the dam. If you look at the map, Deposit, NY is downstream of the Cannonsville Dam. The residents are still bitter that 1000 people, including entire towns, were displaced over a half-century ago when the dam was built. Now they are bitter that they have to worry about the risk of living downstream of a dam. Since a big river flows right through them, they question why N...
