1932+1989 USA-90 Danziger Bridges over the Industrial Canal in New Orleans, LA

1989: (Bridge Hunter3D Satellite)

The formal name for the Industrial Canal is the Inner Harbor Navigation Canal (IH-NC).

When the Industrial Canal was built in 1919, the Almonaster Avenue Bridge carried the Old Spanish Trail across the canal. That road was designated US-90 in 1926. In 1932 the new Chef Menteur Highway including the 1932 Dansiger Bridge was opened and US-90 was moved to that route. [Bridge Hunter Description]

I normally don't bother with a portal view, but this lift bridge design is unique and this is the only way to see the counterweight.

Almonaster Avenue is now closed across the canal. US-90 traffic was moved to the Danziger Bridge in 1932.

This is the Almonaster Avenue Bridge in New Orleans, LA. It is a bascule bridge that was built in 1919 and carries Almonaster Avenue and two railroad tracks over the Industrial Canal.

[That is a really high clearance for the I-10 bridge given how narrow the navigation channel is.]

The oldest view I could find was Oct 2007 and it also had a Bridge Closed sign.

Old Bridges and Dam at Alton, IL


I already have notes about the road and railroad bridges and L&D #26, but I wanted to provide an overview of the old bridges and dam since they are close together and they no longer exist.

They were near downtown Alton where the new US-67 bridge still exists.

Railroad bridge into Alton, Il.
Quite often This area is the confluence of the Illinois, Mississippi, and Missouri rivers The north bound portion of the highway is elevated, during the Big flood of 93 the water was lapping at the outside line on the highway.
[The old road bridge is on the left and the old Lock & Dam #26 is on the right.]

The western abutment of the old dam along with its earthen dike still exists.

Historic Allanburg Bridge (Welland Canal Bridge 11) in Allanburg, Ontario, Canada. The Parker through truss vertical lift bridge carries Regional Road 20 (Hwy 20) over the Welland Canal. The bridge has a 200 ft main span with a 120 ft vertical clearance when opened. It was built during the 1920s as part of the 4th Welland Canal expansion project (1913-1932).

See the Glendale Bridge (#5) for some photos of details of this standard lift bridge design on the Welland Canal and Historic Bridges for a description of the design.

Here we have the stunning Viking Octantis making her return trip northbound thru the Welland Canal at Bridge 11. So happy I was able to see her in person this afternoon.

On Aug 11, 2001, at 2050, the bridge was lowered on the Windoc before it cleared the bridge. "The vessel's wheelhouse and funnel were destroyed. The vessel drifted downstream, caught fire, and grounded approximately 800 metres from the bridge. Although the vessel's cargo of wheat was not damaged, the vessel was declared a constructive total loss. The bridge sustained structural damage, and the Welland Canal was closed to vessel traffic for two days. There were no serious injuries or oil pollution." [Report]

After working two 12-hour shifts in two days, the operator had a day off. He took pain killers for back pain and drank 2-4 glasses of line at lunchtime. Later he agreed to work an overtime shift later in the day. The accident occurred at 2050. The crossing was closed to  marine traffic for two days and to vehicle traffic for three months.

1920s Glendale Avenue Bridge (#5) over Welland Canal at St. Catharines, ON

(Historic Bridges; 3D Satellite)

This bridge is just upstream from Lock #3.

This bridge has a more extensive description by HistoricBridges than the other lift bridges on the Welland Canal since they are of similar design. I recommend clicking the link at the top.

The Welland Canal connects Lake Ontario and Lake Erie. It is part of the St. Lawrence Seaway, crossing the Niagara Peninsula from Port Weller to Port Colborne, bypassing the Niagara River and Niagara Falls. It is officially known now as the Welland Ship Canal.

New Bow Shapes ("backslash" and "just a bow) and Ducted Props

I've recently noted cruse ships that have what I think of as a "backslash" bow.

[It is going over the East Main Street Tunnel under the Welland Canal.]

Carl Burkett commented on his photo: "With her patented Ulstein inverted X-BOW, OCEAN EXPLORER will cleave the waves in such a way that internal noise and vibration is reduced and the hull's shape reduces slamming against the vessel with little spray on its deck."

I had concluded that the comfort of the passengers is more important than efficiently cutting through the water. But the following taught me that this design is more efficient as well.

Vlieborg departed Duluth this evening after loading beet pulp (animal feed) at the Gavilon elevator in Superior. The small ocean vessel with a unique bow is headed to Northern Ireland. 5/14/2022
MN C-Patch: Here is some information on the Vlieborg and its unusual bow design - a design gaining popularity, along with its unique propeller configuration.
James Burroughs: MN C-Patch She is an Ice Class also, pretty cool stuff.

Eric Saed commented on David's post
I keep hoping her fleetmate, the Egbert Wagenborg, makes a trip into the Lakes because it bears a strong likeness to what a modern day classic-pilot-house-forward Laker would look like.

I was going to title these notes "Backslash Bows," but then I came across this ship that I think of as "just a bow."
NL Maritime & Seafarers posted three photos with the comment: "Ramform Atlas & sister ship Ramform Titan have been in Newfoundland waters over the last number of years. And the Ramform Titan arrived in Bay Bulls yesterday to start the 2022 season.  These vessels are designed with 70-meter [260'] beam (wide) and 24 reals [reels] for a capacity of up to 22 streamers designed for Seismic surveys for oil and gas.  They are a class of amazing ships, the widest in the works."

Their website assumes you already know what these ships do and that you are interested in hiring a ship for your oil company. But I did finally find some overview photos of it in operation. In the middle of gthe photo below, we can see it towing six sounders (pictured further below). The sounders periodically make a big bang. The 22 streamers that are also pulled through the water have lots of microphones to record when the "bang" has reflected off rock below and returned. You can barely see the parallel ripples in the ocean made by the streamers.

This is a diagram of how the sounders and streamers are deployed. 

This view of Ramform Atlas shows why they need a wide ship, but they don't need a long ship. 
"Three variable pitch propellers provide 1.8 Megawatts [2400hp] of power, more than sufficient to tow her enormous spread of multisensor recording equipment. The propulsion system permits full operations with just two propellers, and just one of the fully-separated, dual engine rooms."

This 70m (260') beam ship is big enough to hold a basketball court and...

This is what one of the sounders looks like. I wonder what the sequence of "big bangs" do to marine life. Hopefully they start a survey with some small bangs and then increase the volume so that the marine life that can move understand that they had better get out of the area for a while.

Ducted Propellers

The comment above by MN C-Patch says that the Vlieborg has a "unique propeller configuration." The ship's web site explains: "Nb. 407 and 408 are equipped with a main engine delivering 3000 kW to a ducted propeller. The first ship in this series, Nb. 406 M.V. ‘Vikingbank’ was delivered with a 4000 kW engine with an open propeller." I don't think of a ducted propeller as unique. They have been used for a while on towboats. In fact, a USACE towboat with ducted props has been retired to a museum in Vicksburg, MS. But then it occurred to me that scaling this up to the size of an ocean-going ship could be unique. I was surprised by how much it reduces the horsepower needs of the ships.
