Pedestrian Bridge over Bladder Dam on Temp Town Lake (Salt River) in Tempe, AZ

Marko R, Sep 2014

BridgeHunter calls this a basket-handle through arch. But I believe in a regular basket-handle bridge, the arches just touch at the top rather than crossover each other.

The above photo, which is older, reminded me of the 1999 inflatable rubber bladder dam that was replaced in 2016 by a gated dam.

"Two Manitowoc 3100 series 2 cranes, with 180 feet of cable each, were used to lift the four assembled 87.5-ton bridge structures onto its bearing locations." [tylin]

The bridge was built over the bladder dam.

This view catches the crossed-arch design particularly well.

Third Welland Canal Spillway Gate (The Rush or The Showers)

Ron Dekker posted
Here we have a popular Summer destination back when I was a kid.  Been decades since I've been anywhere near it - and I don't know if the public still has access to it.  This is what I think is called the Spillway Gate on the Third Welland Canal.
[Several comments referred to it as The Rush or The Showers.]
According to some comments, gates now prevent driving there, but one can still walk there. But one is no longer supposed to walk in the outflow.]

Jon Lawrence commented on Ron's post
This was when they drain the reservoir up top. Only seen it happen once.

This is the reservoir to which Jon is reffering. It inundates locks 20-22.

CSX/Clinchfield Bridge over Nolichuncky River near Poplar, NC

(Satellite)

I looked in Yancy, Mitchell and Avery counties in Bridge Hunter, but I could not find this bridge.

When Hurricane Helene wiped out most of the Clinchfield route, I read quite a few comments on Facebook wondering if CSX would bother to rebuild the route. It looks like they are rebuilding the route.

Ron Flanary posted
This is a screenshot from the latest Designs in Orbit YouTube video update on the rebuilding of the former Clinchfield. The bridge at Poplar, NC is now finished with panel track in place. CSX salvaged most of the old spans by fishing them out of the river, repairing and reinforcing, and fabricating new approaches on either side. The piers were also reused but with new concrete added. This work is a triumph of superior engineering technology and modern construction techniques. Well done!

It looks like it has an observation tower at the top.

But it would be tricky to put an elevator in one of those tower legs.

This is not a particularly good view of the bridge, but I saved it because I was surprised to see the English word "Restroom" without a corresponding word(s) from the native language.

1887-1948,1989 Trail/UP/Boise, Nampa & Owyhee Guffey Railroad Bridge over Snake River south of Melba, ID

(Archived Bridge Hunter; Bridge Hunter; no Historic Bridges; Satellite)

"Built 1897, abandoned by railroad in 1948; saved from demolition in the 1970s; purchased & restored by Canyon County in 1989." [BridgeHunter]

"After the section of railroad south of the river was abandoned, Guffey Bridge was sold to Owyhee County for $1 in 1948.  Owyhee County sold it to the Idaho Historical Society in the 1970s.  Canyon County purchased the bridge in 1989 to include it in what later became Celebration Park.  The bridge has been refurbished so that pedestrians, equestrians, and bicyclists can use it to cross the Snake River.  The Guffey Bridge is the state’s largest historic artifact and was listed on the National Register of Historic Places in 1978."

1946 Lake Kickapoo Dam (Red River Basin) near Archer City, TX

(Satellite)

The river is so small that Google Maps doesn't put a name on it. It was built by The City of Wichita for water supply purposes and started filling in 1946. "the dam is rolled earthfill embankment of 8,200 feet long including spillway and maximum height of 62 feet. The tops of the dam have two elevations, 1,062 and 1,059 feet above mean sea level. Maximum design water surface may reach 1,060 feet above mean sea level. The uncontrolled service spillway is concrete ogee bears a crest at elevation of 1,045 feet above mean sea level. According to TWDB 2013 volumetric survey, the lake has a storage capacity of 86,345 acre-feet, encompassing a surface area of 5,864 acres, at its conservation pool elevation 1,045 feet above mean sea level. The dam controls a drainage area of approximately 275 square miles." [twdb]

May Flood 2025: It amazes me how straight and level the top of the spillway is because water is going over the full length.

This excess water will help fill Lake Arrowhead. "Wichita Falls officially picked up another inch of precipitation over the Memorial Day weekend. That brought total rain in 2025 to 17.23 inches, well ahead of the normal of 10.39 inches by this date in the year." [TimesRecordNews  Whoops, I forgot to record the link.]

Triple Locks on Dresden Sidecut Canal to Muskingum River in Dresden, OH

(Satellite)

They have eroded, but there were wide basins between each of the three locks so that boats could go in both directions and pass each other between the locks. The basins were just long enough to allow boats to pass so that the canal could rise 24' in a short distance.

Gaige Maitland, Jan 2023

These three locks lifted Dresden Sidecut Canal out of the Muskingum River Valley. This canal was a short canal that connected the Ohio & Erie Canal to the Muskingum River.

The maximum boat size was 14" by 80'.

Locks and dams were built on the Muskingum River to make it navigable from Dresden to the Ohio River. [CanalSocietyOhio]

To be researched: there is a fleet of three locks up by Coshocton, OH.
