1928+1967 Old Hickory Bridges over Cumberland River in Nashville, TN

(Archived Bridge Hunter; Historic Bridges; Satellite)

The 1,222' (372m) long bridge has a main span of 323' (98m). Average daily traffic is 30,080. [BridgeHunter]

We are facing westbound so obviously the northern (right side in photo) bridge is the older bridge.

I could not find an elevation photo of the bridges. Both bridges have three spans.

Old Hickory Bridge in Nashville in 2006
Larry Law: You needed a pass to enter Old Hickory during world war ll due to the secret work they were doing at DuPont and Rayon City. That’s why the bridge has those guard houses so police could stand out of the rain and cold.

The truss bridge replaced a suspension bridge that was built in 1918 for pedestrian traffic. That bridge had a 540' (165m) main span. Later, it was determined that it could handle cars and flagmen were stationed at each end 24-hours a day to regulate use of the one-lane bridge. [bridgemeister]

"While the bridge had two towers at each end, the 540-foot span had no supports to prevent sidesway and literally swayed back and forth, hence the name 'swinging bridge.'"
[I had noticed a Swinging Bridge Road in the area.]

For bridges that are high enough to clear shipping lanes, the approaches can be a challenge. Here a loop was used to gain elevation.

The bridge opened in 1993.
"The bridge, spanning a total length of 798 meters [half mile], features a two-layer structure: the upper deck accommodates the Metropolitan Expressway, while the lower deck is designated for general roads, pedestrian walkways, and the New Transit Yurikamome line."
The height of the towers was restricted because of the nearby Tokyo International Airport.

A lot of sources make a big deal about the solar-powered lighting, but the towers are normally white. They are lit up in rainbow colors during holidays.

Beebe Bridge (Wenatchee, Washington)
1962 U.S. Route 97 steel arch bridge over the Columbia River at Chelan Falls, Washington. The bridge is a continuous through truss tied arch. The bridge was built to replace a 1919 suspension bridge.

Here is a nice view of the old suspension towers as well as the bridge.

1919 Beebe Bridge
Photo by Mrs. Dale Yetter taken in the spring of 1919. This bridge was built by the Beebe Orchard Company to carry two 12-inch water flumes over the Columbia River from springs on the west side to an orchard on the east side.
A 12-foot wide roadway was later constructed between the water lines to transport fruit. The flumes were removed in 1926 and the private toll bridge remained in use until it was replaced by the current state bridge in 1963.
The concrete towers that supported the original structure can still be seen today.

I don't know why Historic Bridges didn't document this bridge; they have documented other bridges in Douglas County. It looks like the bridge uses rivets instead of bolts or welding.

1908 Camas Prairie Railroad Lawyer's Canyon Bridge near Craigmont, ID

(Bridge Hunter broke Mar 22, 2023; no Historic Bridges; Satellite)

According to a comment by Drew Mango on a post, an abandoned section of the Camas Prairie Railroad has over 40 wooden trestles. The movie Breakheart Pass was filmed on one of the wooden trestles.
Chris Jones: the locomotive used in that movie, Great Western 75, is now at the Heber Valley Railroad in Utah

As this sign explains, the route was jointly owned by NP and UP. According to a USGS map, it is now owned by Bountiful Grain & Craig Mountain.

2024 Chenab Bridge in India, "World's Highest Bridge"

(Highest BridgesSatellite, 305 photos)

The red&white structure in the upper-left corner in the photo below is one of the two towers that held the cableway that was used to construct the arch.
IndianExpress, Express Photo by Gajendra Yadav
"It stands at the height of 1,178 feet [359m] above the riverbed, making it 35 metres taller than Paris’ tourist icon, the Eiffel Tower."
Even though it has been over two decades since the bridge was approved in 2003, the construction of the arch took just three years.

TimesOfIndia, 1 of 9 photos
They have run a trial train over the bridge. The main arch is 467m (1,532', 0.3 miles). The bridge is 1.3km (0.8 miles) long. Part of the delay was that the mountain slopes required extensive stabilization to anchor the arch.

The construction of the arch of the world’s #highest_railway_bridge that soars 359 meters above the bed of the #Chenab river in Jammu and Kashmir was completed in #India.
The 1.3-kilometre-long [0.8 mile] bridge aims to boost connectivity to the Kashmir Valley and it is being constructed at a cost of ₹ 1,486 crores as part of the Udhampur-Srinagar-Baramulla Railway Link (USBRL) project.

Why Chenab Bridge has Single Track..?
The Chenab Bridge in India, a significant engineering marvel, has a single track primarily due to several technical and practical considerations:
1. The design of the bridge is optimized for a single track to ensure structural stability and safety. A single track allows for a lighter, more flexible structure that can better handle the dynamic loads of passing trains and environmental stresses like wind and seismic activity.
2. As the world's highest railway bridge, Chenab Bridge holds significant importance for tourism. To enhance the passenger experience, the bridge has been designed to be wide enough for passengers to stand on both sides and enjoy the breathtaking views & also can be used for maintenance purposes.
Furthermore Tunnel on either side of the bridge feature single tracks. Laying double tracks inside the tunnel poses a risk of destabilizing the surrounding mountains. 
3. The current and anticipated traffic on the railway line does not justify the need for a double track. The single track is sufficient to handle the expected train traffic, especially given the current stage of development in the region.
4. A single track reduces the complexity of maintenance and operational management. It simplifies the monitoring and upkeep of the bridge, ensuring long-term reliability and safety.
Overall, the single track design of the Chenab Bridge is a balanced approach that aligns with the engineering, economic, and operational requirements of the project.

Hometown Trestle over Little Schuylkill River

(no Bridge Hunter; no Historic Bridges; Satellite)

River Rail Photo posted
Hometown Hero At Hometown Trestle. With its restoration essentially complete and a few smaller test runs under its belt, the Reading and Northern Railroad - Passenger decided put RBMN T-1 2102 (4-8-4) to the real test. Not having operated from 1991 until this month, the engine was solo on the assignment to move 50 coal hoppers from North Reading, Pa to Jim Thorpe, PA and back to Tamaqua, PA on Tuesday, April 26, 2022. Just a few miles from ending its day, the train is seen crossing the Hometown Trestle in Hometown, PA. The 50 empty coal hoppers were determined to be approximately the same weight as the planned 18 car consists that this local fan favorite engine will pull in the very near future. A word from the wise: expect crowds onboard and along the route.

Hometown High
For this week's Steam Sunday here's a fresh one taken just last weekend of the one and only Reading and Northern 2102 on the famed Hometown High Bridge.  I have shot steam here twice prior but never got sun, so decided to give it another try.  Not sure if it was the sage smudging my gf insisted on the night before to ward off the negative energy after a horrible Friday, but whatever it was it sure did work because I finally scored with perfect light and even some early fall color.  Quite the Hometown High indeed! 
They are leading a 14 car train up from North Reading to historic Jim Thorpe across the most spectacular location along the route, the famous Hometown High Bridge, a more than 1000 ft [305m] long steel trestle that stands 168 [51m] (or 161 or 157 depending on where you look!) feet above the Little Schuylkill River at its highest point.  This is MP 107.3 on modern day RBMN's Reading Division mainline, though historically this was the Central Railroad of New Jersey's Nesquehoning Branch. 
A little history of the line courtesy of Rush Township's home page: 
The Nesquehoning Valley Railroad Company, part of the Lehigh Coal & Navigation Company, built a 17-mile rail spur from Mauch Chunk (modern-day Jim Thorpe) to Tamanend that was finished in 1870. It connected with rail lines that were leased and operated by the Philadelphia & Reading Coal and Iron Company near Tamanend. This major freight and passenger rail interchange was at the small village of Haucks, which no longer exists today but was near the current Air Products facility near Quakake. Throughout the late 1800s, there were railroad interchanges in Haucks, Tamanend, and Quakake. On March 23, 1871, the Nesquehoning-Tamanend line became part of the Central Railroad of New Jersey (CNJ), which leased many LC&N assets on that date. 
Millions of tons of anthracite coal and freight would pass over that rail line in the early 1870s, and the demand for anthracite coal reached historic heights. In 1874, a financial panic led to a downturn in anthracite demand that would last several years. The CNJ, which had continued to rack up debts as it leased other anthracite assets across Eastern Pennsylvania, could not meet its financial obligations. The company continued to operate until the 1920s, at which point the United States Supreme Court ordered CNJ and other railroads that owned coal companies to divest (that is, to separate the coal companies from the railroad companies) because their joint operations violated the Sherman Anti-Trust Act and the Hepburn Act. By 1921, the Central Railroad of New Jersey was out of the coal business – and railroad traffic on Rush Township railbeds continued to decline. 
The Nesquehoning-Tamanend line features the railroad “High Bridge,” which spans the Little Schuylkill River at a height of 157 feet. The bridge is cited in historical documents dating back to at least the early 1880s. The bridge, formally called the Hometown Trestle, is 981 feet long. The original bridge was a massive wooden structure, but it was rebuilt out of steel in 1931. 
As for 2102, the stout 4-8-4 was built in the Reading Company's own shops in 1945 and from the railroad's corporate website here is a bit of history: 
The company, using parts from a former 76-foot Class I-10sa Consolidation 1923 Baldwin locomotive, created a fleet of 30 middleweight engines in the T-1 series. The goal of building these locomotives was to be able to haul both freight and passenger traffic along the rails. 
The original Baldwin-built I-10 class, which were large 2-8-0 locomotives, would become the T-1 class, converted to much larger 4-8-4 engines by redesigning and lengthening the Boiler and replacing the Frame and Wheels with brand new parts. Baldwin supplied the parts, but the rebuilding was done in the Reading Railroad’s own Shops right in Reading, PA.

I included the Reading Railroad in this excerpt because I thought it was interesting how they used Pine Creek to climb out of the Little Schuylkill River Valley. They were already in the valley because they used the river to get past Locust Mountain.
