"Anacostia" tower

This tower is at the Junction of the CSX Capital Sub. 

It's still there as a bridge tenders Office for the Local Lift bridge ( Mostly in the summer)

Here is a photo of the tower I shot from the train, during one of my many trips from Potomac Yard. This was during the Chessie System era and prior to CSX. I am not sure of the exact date.

The fence messed up the autofocus, but there appears to be a second story roof on the right side of this view. That is the location I selected for the satellite link at the top. However, that location is on the north side of the tracks. However, the bridge and yard tracks in Richard's photo implies the tower was on the south side of the tracks. But the only thing I saw there was the Benning Yard Office, which clearly looks different.

1909,2003 Shelby Street and 2004 Gateway Bridges over Cumberland River in Nashville, TN

I presume the name of the Shelby Street Bridge was changed to the John Seigenthaler Pedestrian Bridge in 2003 when it was rehabbed as a pedestrian bridge.

The 1,777' (572m) long Shelby Street Bridge has a main span of 318' (97m). [HistoricBridges]

The 1,600' (488m) long Gateway Bridge has a main span of 545' (116m).

"Significance: The bridge possesses state level engineering significance as an example of the through Parker and camelback truss types and for its uncommon concrete trusses. The bridge possesses local significance as a historic river crossing connecting downtown Nashville with East Nashville." [HAER_data]

1909 is getting rather late for pin-connected construction. It is nice that an historic truss was preserved.

Well, I wasn't sure it would happen BUT I did find something appropriate to post for you Ship Junkies in Nashville today!  Tug Carolyn Lamprey (built 2019 by Bourg Drydock) and her barge came pushing along the Cumberland river with a full load, just when I was on top of the John Seigenthaler pedestrian bridge taking in the sights.

*Tug Carolyn Lampley, is named for the sister of the late Ron Hunter, who founded and was president of Hunter Marine Transport—a barge and towing company with more than a dozen towboats—that Kent Furlong bought in 2018. Hunter died in 2017 after a 40-year career, the capstones of which were building the barge line as well as developing a bulk terminal operation and a sand and gravel dredging enterprise.

That's all I got!!

HistoricBridges explains that the concrete trusses on the west side had to be replaced after just a few years because the defective concrete started spalling. But I see they lasted on the east side. This is why the label "bridgeArch" was added to these notes.

8/29/22: Officially the Maurice J. Tobin Memorial Bridge, most know it simply as the Mystic River Bridge that connects Boston to Chelsea, Massachusetts. Built between 1948 to 1950 it’s New England’s longest bridge at 11,906 long, 36’ wide with three lanes on two levels.

We’re looking north here from Boston Inner Harbor.

Why do the northbound and southbound lanes have different heights?

Because it is a double-deck bridge. [HistoricBridges]

"The bridge provides three travel lanes northbound on its lower level and three lanes southbound on the upper level." [wfrjr]

On the Chelsea (north) side, there are local lanes as well as through lanes.

Little Mystic Channel truss span

Did they build across the navigation channel from the far pier to the temporary pier with no intervening falsework? A span with no live load may be strong enough for that. Normally, cantilever bridges are built from both ends and meet in the middle to avoid falsework in the navigation channel.

We see the predecessor swing bridge that used to open 7,000 times per year. [BostonRoads]

Carol Donahue: My four children were on the bridge when it collapsed. They had to stay on the bridge until all the cars behind them turned around back to Chelsea in order to get off. The driver in the truck that caused the accident was killed.

Kathleen Manganelli: I called the police on this one. THe crash woke me up!

One of the problems with AI is that nothing has any attribution. In particular, what was the source of the renaming information?

1845-1899 Old Beauharnois Canal and Aqueduct

The Old Beauharnois Canal was completed in 1845. The Soulanges Canal opened in 1899. The Beauharnois Power Canal opened in 1932. The two locks at the end of the power canal were added by 1959 as part of the St. Lawrence Seaway project. The Soulanges Canal was closed when the Seaway opened because those two locks could do the work of the five locks on the old canal.

"Swing span currently locked in open position. Proposal has been made to semi-permanently close this draw span (which sits over heavily silted, now-non-navigable waterway) and incorporate it into local waterfront trail system." [ArchivedBridgeHunter]

I captured this view as well because I was surprised that a big sanbar disappeared during a couple of years.

Most of the bridge is still a wood trestle.

Being in the passenger seat of a tractor trailer for once allowed me to take these pictures of which I normally wouldn't be able to get them.

I've never noticed WM on maps of Baltimore, so I went back to basics to see where it entered the city.

Given that it came in from the northwest and Jim's comment about going to Port Covington Yard, I was able to find the WM route through town.

Port Covington no longer has any freight business.
