Peter Kilfoyle: Is that the working trestle? Or should I say the former working trestle?

Rob Meredith commented on Peter's comment

My guess is that Anita's photos are from the west bank because the abutment is on the outside curve of the river. The current of a river is strongest by the outside curve.In fact, some rivers will build a sandbar on the inside curve.

They did line the bank with some big rocks to try to avoid erosion of the bank, but they did not do the job. Fortunately, the abutment did do its job and continued to hold the truss in place.

US-163 Bridge over Comb Wash near Bluff, UT, washed out by Nov 1, 2026 Flood

(Satellite)
It is easier finding a bridge when you can look for the road closed markings on Google Maps. A popup says the road is closed until late Jan 2027.

Nov 1, 2026, flood

I can't tell if the bridge uses steel or concrete girders. Note the exposed pilings under the pier cap.
Facebook Reel
A section of the Comb Wash bridge along Highway 163 southwest of Bluff is gone. It was washed out Sunday night when flooding in the wash was just too much for it. Work crews are already figuring out how to get it fixed fast

If you look closely, you can see a puddle remaining in the wash.

This is the only street view that had significant water in the wash. But it is a long way from topping the bridge.

It looks like every span is skewed.

Indeed, the spans are skewed to keep the piers parallel to the flow of water.

Service Road Trunnion Bridge over Aux Lock at Mississippi L&D #14

(Satellite, approximate since it is new and does not show up on a satellite map)

This bridge accesses the island between the Le Claire Canal and the Mississipppi Lock and Dam #14. It goes over a lock that is used by the USACE maintenance equipment. The commercial lock is further east.

Jan Danielsen posted five photos with the comment: "Up and then down., The new Bascule Bridge in the canal near lock and dam 14. Pictures taken from Pleasant Valley, Iowa. 10-27-26."
Douglas Butler shared with the comment: "Credit to Jan Danielsen : The new Lock & Dam 14 Drawbridge is in Pleasant Valley, IA."

[The building and fixed bridge that is in this photo. So the new bridge is upstream from the old fixed bridge. The design of the bridge is simple; it uses two hydraulic rams to move it. In the photos below you can see the counterweight.]

In order to use this lock, they would have to removed the fixed bridge. Here is a view where they are placing a barge under the bridge to remove it.
Walkway View, Nov 2015

And here we see the bridge "parked" upstream of the upper gate from a boat that is going upstream in the lock.
Boat View, Oct 2015

And they probably have to put the bridge back after the boat leaves. The new drawbridge will save them a lot of hassle with the fixed bridge for each locking.

US-67 Bridges over Lake Wappapello/St. Francis River at Old Greenville, MO

1911 MO-25 1911 Bridge over St. Francis River


The spindly trusses on the right were the road bridge.
BridgeHunter_1911

The main span was a Pennsylvania through truss. It was pin connected.
BridgeHunter_1911

1931 US-67/Railroad 1909,1931 Bridge over St. Francis River


This bridge was built by the Williamsville, Greenville & St. Louis Railroad in 1909. It is the heavier truss in the above two photos. After the railroad went bankrupt and abandoned the bridge, it was widened in 1931 and replaced the 1911 bridge. The above two photos were taken during that conversion.

In 1927, MO-25 was designated as part of US-67. The conversion of the bridge was because of the new status of the route as a US highway; and the road was realigned, widened and paved. The conversion widened the truss by 6' (1.8m) and built new approaches. The 180' (55m) pin-connected truss was acquired from MoPac when MoPac replaced it with a double-track span. When the USACE had to replace this bridge, they reused the truss "over the USACE's St Francis Bay Ditch on Arkansas Route 42 by J. P. McNulty of Pine Bluff. [ArchivedBridgeHunter_1909]

The converted railroad bridge is on the left, and the 1941 bridge is being constructed on the right. The USACE didn't need to raise the bridge a lot to clear the Wappapello Dam's  reservoir.

1941 US-67 Bridge over Lake Wappapello


Because the Wappapello Dam was built in 1941, the USACE had to replace the converted railroad bridge.

Dakotah Green: How can i get more information on the history of that bridge I used to ride by it with my dad when I was little and always wondered about the history of it?
Rusty Weisman: Dakotah Green if you are ever at old Greenville, go to the old Bettis Ford just downstream from the new 4 lane bridge, where you will find a wayside interpretive panel about the history of that bridge and its predecessor that I produced when I worked at MoDOT. That work was done as part of compliance with Section 106 of the National Historic Preservation Act, which requires agencies using federal funds, or federal lands or requiring federal permits to consider the effects of their undertakings on historic properties, and when they are adverse or harmful to take steps to avoid minimize or mitigate the damage. To mitigate the damage to Old Greenville including removal of the 1945 bridge we developed a series of interpretive panels so the visiting public would have a chance to learn about the local history, including the 1945 bridge.

Nathan Holth commented on BridgeHunter_1941
Based on some digging through MoDOT info, apparently the attached sign is located at the former site of this bridge.

Actually, there are four signs at the bridge location.

During the 19th century, travelers passing through Old Greenville had an important decision to make. How would they get across the St. Francis River? There was no bridge crossing the river required use of either the ferry or the ford.
The firm gravel river bottom and wide shallow channel allowed travelers to safely use the ford for much of the year, However, during periods of high water and cold weather, fording the St. Francis River at Old Greenville was both impractical and dangerous.
Cost was a factor for many travelers. The ford was free, but for a traveler on foot, the ferry cost an hours wages and for a four-horse team and wagon, the fare was an entire day's pay. Those who were unable to pay for the ferry could either turn back, wait for the river to fall, or risk their lives in the current.
The earliest description of the river crossing was recorded by Henry R. Schoolcraft. In 1821, he published a journal describing his travels through the Ozarks in 1818-1819. On January 28, 1819, when Schoolcraft arrived on the opposite shore, rather than wade across the river, he chose to employ the ferry. However, he lacked the coins to pay the exact 10-cent fare and found that the slave operating the ferryboat had no change. In his journal, Schoolcraft noted that the ferryman solved their problem at a nearby oak stump "according to the Kentucky mode," where an ax was used to cut a 10-cent slice of silver from one of his half-dollar coins.
The bridge was built here in 1892 for the WG&StL Railway. In 1899, that bridge collapsed beneath a log train. Wayne County contributed $750 to help the railroad build a replacement structure with a dual-use bridge deck that also allowed use by foot and wagon traffic. By 1908, that wooden 100' Howe truss bridge had deteriorated and public outcry compelled the railroad to replace it. The railroad acquired a used steel bridge (A) and set it on new concrete piers. That relocated steel Pratt truss railway bridge opened in 1909.
The railroad steel bridge was not designed for dual use. So in 1911, the county contracted with Stupp Bros. Bridge & Iron co. of St.Louis for a separate county road bridge (B) remained in use until 1930. It was replaced by the State Highway Department who acquired the railroad's then abandoned steel bridge. The Highway Department widened that old steel truss by six feet and built new concrete approach spans and new road deck, converting the railway bridge for use by U. S. Highway 67 (C).
The modified 20'-wide former railroad bridge (C), carried Route 67 over the St. Francis River from 1930 until 1941. In 1941, when a replacement at higher elevation became necessary, due to construction of the Wappapello Dam 20 miles downstream, a new bridge with a 170' Warren through truss main span was built (D). It remained in service for 70 years. The 1941 bridge was demolished in 2011, after completion of the current four-lane Route 67 Expressway Bridge (E).

They must have painted the steel girders white because the above looks like concrete girders but this construction photo shows that it used steel beams.

A lot of falsework was needed to build the truss.

The description on the above "Historical Wayne County, Missouri" post mentions "Old Greenville."
Greenville used to be down by the river. By the 1966 topo map, the town had been moved to its present location on a hill.

Sabino Dam


Meteorologist Chris Nunley posted
Significant flooding is underway in Arizona! Stranded visitors are being rescued due to flooding. This is Sabino Dam in Sabino Canyon Recreation Area in the Coronado National Forest. Do not attempt to cross washes or canyons.
Larry Gruetzmacher: Where is all this water going?? Anyway to divert it to where it's needed??
Kevin DeFilippo: Larry Gruetzmacher the water goes from the washes to the Rillito river and Santa Cruz river to the Gila river..
[I traced the Gila River. The Colorado River goes into Mexico soon after the Gila River joins it. This is probably downstream of all the USA Colorado River reservoirs.]
Heather DuVall: Parts of Camp Verde and Cottonwood under 5 feet of water.
James Andrew Mac: Everyone knew this was coming 4 days ago , why were people still allowed there?
Lawrence Walker: Same as Kerr County, Texas, in both 2025 and 2026, where so many people ignored the severe weather forecast.

As a farmer, we love water. All aspects of it. How it sustains life here in the desert. How we catch it and keep agriculture and the population going on drought years.
Lots of people have asked us where does all this water that’s now running down the rivers end up? For the salt river that’s flowing through Phoenix now, it ends up in the Gila River. And then the Gila River ends up in the Colorado river. From there, it makes its way down into the sea of Cortez in Mexico. Most years there is no water flowing down the river, and so very little water ends up hitting the sea of Cortez. On our wet years like this one it will.
all this happens after our immense man-made reservoirs are full. Those reservoirs were built by our pioneer ancestors to supply life giving water in the drought years. It’s a wonderfully engineered solution to the problem of water here.
[Roosevelt Dam and Painted Rock Reservoir catches the water in the Gila River watershed before it reaches Mexico.]

Eight days apart. Same spot! 🌵
With flash flood warnings all around us, here’s some of the flooding near Queen Valley from the dam.  It’s amazing how quickly the desert can change with significant rain. 
Never underestimate the power of Mother Nature!

Stella San Miguel: Where is this please?
Dennis DeBruler: Stella San Miguel It looks like the outlet for the Whitlow Dam upstream of Queen Valley, AZ: https://maps.app.goo.gl/uoekLGqSFnBKTdRg6

This looks like a surge basin dam. That is, the reservoir is normally empty and the amount of water that goes down stream to Queen Valley is limited to the capacity of the outlet works. In this view, we see an empty reservoir and the control works house for the outlet works in the background.
John, Oct 2026

They must be confident in their estimate of the needed capacity because it is an earth dam, but I don't see an emergency spillway.

SEVERE FLOODING | SOUTHWEST COLORADO
This is the force of flooding currently impacting southwest Colorado.
The worst may still be ahead. Rivers across the region continue to rise, with some of the most severe flooding expected late tonight.
Residents are urged to stay away from flooded roads, bridges, and waterways as dangerous conditions continue throughout the region.

Google Maps doesn't know about "Hermosa." At  least this bridge needed a lot of debris to help take it out.
