C&NW Grain Elevator Along the Main Stem of the Chicago River

(Satellite, the land was occupied by Sun-Times and is now occupied by Trump Tower)

This elevator was served by the C&NW/Galina & Chicago Union railroad and it was located in its State Street Yard.

Mile 326.4 A cofferdam was built in 1902 so that workers could pour concrete for the subsection of the State Street Bridge. But the wooden barrier often leaked, which added to construction delays. This view is from the south bank looking northeast. The Rush Street Bridge is in the background. — The Lost Panoramas, May 16, 2013

A view from the Chicago River looking toward the east side of State Street on the north side of the Chicago River on February 25, 1902. The stairway at left leads up to the street and what remains of an old State Street bridge that was being replaced. The new bridge would be completed in 1903 and was later replaced with the current bridge in 1949.

The bridge that comes from Sweden turns into a tunnel under the sea and reappears in Denmark; both countries united by this wonderful work of Engineering.
It has a total length of 16 kilometers and connects Denmark with Sweden through the Øresund Strait. The Oresund Bridge was built in 2000 and allows the passage of cars (highway) and trains between Denmark and Sweden. Before its construction, all traffic between the two countries was carried out by ferry.(Las huellas del pasado quote)

Charles Olson: Fun fact: the transition from bridge to tunnel was originally planned to be built on a nearby island named Saltholm (Salt Island). For environmental reasons they decided to build an artificial island instead, and named it... Peberholm (Pepper Island).
James Simms: On the Copenhagen side, work was delayed as engineers & construction workers discovered numerous bombs fromWW2.
KevandSus Dickman: One way is about $55. If you have a season pass it's about $23 one way.

Oresund Bridge Between Sweden and Denmark is, Longest Bridge and tunnel in Europe !! 

The bridge that comes from Sweden turns into a tunnel under the sea and reappears in Denmark; both countries are united by this beautiful work of Engineering.

It has a total length of 16 kilometers and connects Denmark with Sweden through the Øresund Strait.

John Rich: The Chesapeake Bay Bridge-Tunnel in Virginia is 18 miles long or about 30 km.
Patrik Wirén: It's only the fifth longest bridge in Europe.

 The Öresund Bridge is a combined bridge and tunnel system that connects the Swedish city of Malmö to the Danish capital, Copenhagen. It is an impressive engineering marvel that spans across the Öresund Strait, connecting the two countries. The bridge is approximately 8 kilometers long and includes a 4-kilometer underwater tunnel. The Öresund Bridge serves as a vital transport link, facilitating both road and rail traffic. It has greatly improved connectivity and accessibility between Sweden and Denmark, making it easier for people to commute and travel between the two countries. The bridge has also had a positive impact on trade and tourism in the region.

I believe the type of "immersed tunnel" means that it is cut&fill like the Germany-Denmark Bridge rather than dug with a tunnel boring machine.

"The new 12-lane bridge includes 4 side-by- side, double leaf bascule spans, each with a 82m (270') center-to-center trunnion spacing and an overall bridge width of 76m (250'). The bascule span is supported on delta-shaped concrete bascule piers. Provides a 53m (175') horizontal channel for navigation. Open position affords unrestricted vertical clearance within designated channel and a 21m (70') minimum vertical clearance, span closed, for navigation."

"The $2.35 billion Woodrow Wilson Bridge Project was featured on the Discovery Channel’s Extreme Engineering Series and was termed 'the world’s largest drawbridge.' The Project has received over 70 major awards, including ASCE’s Opal Award, and has been referred as ‘Washington DC’s Newest Monument’ which has successfully eliminated the worst traffic bottle neck on Interstate 95 between Maine and Florida."
[I can't reconcile the $2.35b cost with the $600m and $680m figures I saw in other sources. Perhaps the billions include highway interchange improvements and environmental protection projects as well as the bridge itself.]
The 1000 steel pipe piles where up to 72" in diameter and 210' long. "Amazingly, over the course of 15 years of design and construction, the cost of the project was actually reduced by $86 million from the original estimate of $2.44 billion to the final cost of $2.35 billion, thanks to diligent program management and cost control by AECOM and our partners."

A cathedral of engineering--the Wilson Bridge spans the Potomac between Virginia and Maryland and is a place of grandeur and beauty. Beneath the 12 lanes of traffic that the bridge supports, the combination of the V-piers and the girder haunches form an architectural motif of arches suggesting cathedral vaulted ceilings. The details of the arched piers are what drives me to come here again and again to photograph. Even though there is the constant hum from the traffic noise above, people find sanctuary among the arches to picnic, ride bikes, play ball games, fish, jog.

Mark Ramey posted
Long before the Ship Canal Bridge and even before the University Bridge, there was the Latona Bridge!  Built in 1891 and demolished six weeks after the University Bridge opened in 1919.

Barbara Abelhauser: I'm a bridgetender at University bridge. I may have to print these pictures out and put them on the wall in the tower. Thank you for sharing them! And while it is a beautiful structure, it was wooden and falling apart quickly, so it had to be replaced. There was no choice.

Mark Ramey: Barbara Abelhauser How is the University Bridge holding up?

Barbara Abelhauser: Mark Ramey it's rusty, torqued so that it squeaks when it opens and closes when it's hot, and down below all the plaster is melting away because the dirty water from up above is seeping down. So, in a nutshell, not the best. But it rarely breaks down, compared to the other bridges in town, so it does keep on trucking. It's my favorite bridge to work on. Oh and it's badly in need of a paint job but that's a couple years off.

As with many of our interstate bridges, this one is now falling apart. The parks under both approaches were closed in 2019 because concrete was falling from the bridge! "When asked why the Ship Canal Bridge was allowed to deteriorate, Secretary Roger Millar told the editorial board: 'Because we need to be spending $2 billion a year (on maintenance and preservation) and we’re spending $925 million dollars a year.'...The 182-foot tall structure carries more than 200,000 vehicles a day, and it’s vital to the state’s economy. It has been 22 years since the last major preservation project." [SeattleTimes]

"It is a steel truss double-deck bridge, which carries eight lanes of traffic on the upper deck and four reversible lanes of traffic on the lower deck." [Priscilla Long, License: Attribution-NonCommercial-NoDerivs (CC BY-NC-ND 3.0)]

The eight regular lanes go up and over the four reversible (express) lanes.

Street View

The original approaches to the University Bridge were built with temporary wooden trestles. The 1933 rebuild replaced the approaches and doubled the width of the bascule spans. To reduce the weight of the wider deck, the entire deck was replaced with a open-mesh steel deck. So it must have been a "hummer." The use of an open-mesh steel deck was novel in 1933. I cannot reconcile the description of how they added the extra lanes and walkways with the photos I see today. The description says the new lanes and walkways were cantilevered outside of the truss lines. But the photos show only the walkways are cantilevered. [Engineering News-Record]

As my flight was arriving in Seattle, I snapped a photo and today discovered I caught the University Bridge during an opening.

A 12:52 video starts with this bascule bridge  It refers to the this type of bridge as the "Chicago-style fixed trunnion bascule bridge." And the bridge uses pony trusses, which are above the deck as well as below the deck. At 3:00, the video provides details of the trunnion and the pinion gear in action. (The details may not be of this bridge in particular, but the trunnion designs would be similar.) At 3:39, the video describes the BNSF/GN Ballard Bridge. The video revisits the University Bridge at 8:21.

1917 Lake Washington Ship Canal and Ballard (Hiram M. Chittenden) Locks

(Satellite) The official name for the locks is Hiram M. Chittenden.

"The U.S. Army Corps of Engineers began construction of the Lake Washington Ship Canal and Hiram M. Chittenden Locks in 1911. They were dedicated on July 4, 1917. The 30-foot-deep canal connects Puget Sound on the west with Lake Washington eight miles to the east. A dam, gated spillway, fish ladder, gardens, visitors’ center and two navigation locks are located 1.5 miles east of the entrance on Puget Sound. The locks and canal materially contribute to the industrial, municipal, commercial, environmental and recreational development of the area while serving multiple functions: (1) Controlling the elevation of Lake Washington within a narrow range allows for east-west highway traffic across two floating bridges, Interstate 90 and Washington State Highway 520, which are key to commerce for Ports of Seattle and Tacoma. (2) This is the busiest navigation lock in the nation. The Alaska fishing fleet is home ported in Lake Union. The canal and locks provide a navigation link from freshwater Lake Washington and Lake Union to saltwater Puget Sound. (3) The fish ladder and locks are the only connection for salmon moving from Puget Sound to freshwater Lake Washington and its 607-square-mile watershed. (4) The Locks is a popular destination in Seattle and receives more than 1 million visitors per year." Once again, we have a major civil engineering project over 100 years old that has become a funding issue. In this case, a loss of pool would not only jeopardize a lot of commercial boating, but a $10b floating bridge infrastructure. (I-90 is one of those floating bridges.) [USACE-canal]

A video about the drawbridges over the ship canal

Canal bridges that I have documented so far are:

• BNSF/GN Ballard Bridge
• Lost/NP Bridge
• I-5 and University Bridges

Look at the number of pleasure, and maybe fishing, boats queued up in both directions to use the small lock. Maybe they should do a batch or two of boats through the big lock.

Satellite

It looks like they do sometimes put a batch of boats through the large lock.

The BNSF/GN Ballard Bridge is in the background.

BallardLocks, the map is interactive on the web site.

MyBallard
Once in the lock, the water level drops as much as 26 feet to bring the boats even with Puget Sound. The fresh water is exchanged with salt water. Ten to fifteen minutes after the process began, the boats are on their way. During busy times, though, long lines of boats form on either side of the locks.

MyBallard
A viewing area allows visitors to watch one of the last “weirs” before the spawning fish head into freshwater. The best time to see large, spawning king salmon is in mid to late-August. For coho salmon, late September. For sockeye, the month of July. And for steelhead, late February through March.

This aerial caught the dam spilling quite a bit of water. Since there is no hydropower plant here and there is a lot of rain in the Seattle area, the only priority for this dam is maintaining the correct water level for Lake Washington. The locks and dam also prevent saltwater intrusion.

USACE-lock
"The complex includes two locks, a small (30 x 150 ft, 8.5 x 45.7 meter) and a large (80 x 825, 24.4 x 251.5 meter). The complex also includes a (235-foot, 71.6 meter) spillway with six (32 x 12-foot (3.7 m), 9.8 x 3.7 meter) gates to assist in water-level control. A fish ladder is integrated into the locks for migration of anadromous fish, notably salmon. The grounds feature a visitors center, as well as the Carl S. English, Jr. Botanical Gardens."
This web site has several videos including a Fisherman's Terminal video (satellite) where much of the Alaskan fishing fleet spends its offseason.

I realize this photo is of the same bridge I posted (and photographed) yesterday...the Salmon Bay rail bridge, but I thought those who do not live in the area might be interested in the location WRT Seattle and what the area looks like where the bridge crosses the ship canal. The open waters of Puget Sound are to the right (west in the photo). This view is looking south from a pontoon plane I was on for a flight to Victoria, BC a few years ago.
Dennis DeBruler: And that is a nice view of the Ballard Locks.
