1911 MO-25 1911 Bridge over St. Francis River


The spindly trusses on the right were the road bridge.

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

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 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.

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.

I hope those campers don't need that bridge to get back home. Actually, do they need it to get to higher ground.

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.

Upper & Lower Goldwater Dams: (Satellite) I could not find a name for the creek that runs through here.
Willow Creek Reservoir: (Satellite) This is fed with a pipe from the Watson Dam.

Nov 1, 2026: It is designed to handle 10' (3m) of over topping. Note how water is blasting out of the outlet conduit, as it should be.
Facebook Reel
Latest update from our City Mgr Dallin Kimble as of Sunday 11/1 at 11:30 am below.  The net is please stay home today! Our rescue crews have their hands full and don’t need to rescue you too.
Watson is rising 3" about every 2-3 minutes. The recharge pipeline is open, the 36" valve is open, and the pipe to Willow is open, there is water flowing over the spillway, but there is just too much water coming into the lake. The dam is rated for water to be able to flow up to 10 feet over the top of the dam, but any amount of overage creates structural risk.
SEE NEW VIDEO!! As of 11:30 am:  We're now topping at Watson and Upper Goldwater. There's only about 6 feet of capacity left in Lower Goldwater. It will top as well. We're notifying the affected neighbors downstream.
There are various areas around the city where we may need to close roads, including Willis. LaGuardia Bridge is doing well. The Prescott Lakes Parkway bridge is also holding up.
Beyond our borders, Fain Lake Dam is overflowing in PV. They're also very concerned about Lynx Creek.
Senator Highway has washed out and there are rescue operations underway in Groom Creek.
A fire task force from Phoenix is on its way to help on the Verde side.
Please stay home today Prescott!

Because of the 27-year draught, there was plenty of room in the reservoir for the flood waters.

I couldn't reconcile the Facebook image with the satellite image until I used Google Earth to find an image of a more full reservoir. Then it became obvious that there is a spillway on the right descending bank and the reel is at the end of that spillway.

The deck truss was torn down a year or so before the girder bridge was finished. According to a video, the locals were glad to see it go because DOT kept closing it for repairs. One person said that it should have been replaced a couple of decades ago.

"Demolition underway on Lake Herrington's Kennedy Mill Bridge"
It was in such bad shape that it was torn down piece by piece before the new bridge was done.


The Walsh Group posted
Throwback to October 2017, when we placed Miraculous Medals in the first concrete pour for the new Kennedy Mill Bridge over Herrington Lake in Harrodsburg, Kentucky. The project included the replacement of a 93-year-old, 804-foot-long bridge, along with  demolition and removal of the existing structure.

It looks like a combination of steel and concrete girders, mostly steel.

Dix Dam


"Upon completion in 1925, the dam was considered an engineering marvel, Kentucky’s first hydroelectric dam, the world’s largest rock-filled dam and the highest dam east of the Rocky Mountains." [lge-ku]

Jushua James Pretzer posted eight photos with the comment: "Dix Dam, Kentucky."
Joshua James Pretzer: Painter now part of E.W. Brown Generating station that they built nearby. I was told that having the hydro plant has allowed the coal fired units to continue operating when similar plants have been shut down. And that the coal side is now used to experiment with new cleaning process to learn how to update aging coal plants.
Of course I don't know if any of that is true I'm just the crane guy. And now that I think of it I think most of the coal units have been down for a while. Only 1 of 3 units seemed to be active when I was there.
Steven Painter: Joshua, What a neat old plant, How many megawatts does this produce? too bad they are shutting down all the coal plants, this will not be good.
Joshua James Pretzer: 33MW
[A Google Maps label says the dam is permanently closed.]

At 249' (76m) deep, Herrington Lake is the deepest lake in Kentucky.

weku, 1 of 12 photos on this webpage.
The dam is 287' (87.5m) tall with a base of 750' (228.6m).

Google AI says it is 1,087' (331.3m) long. It gave pplweb as the source, but I could not find that fact on that web page.
