1938 US-62 Bridge over Green River at Rockport, KY

"Design: Three-span cantilevered Warren through truss" [BridgeHunter]

In addition to a long through truss, the approaches have long deck trusses.

One reason for long approaches is a wide flood plain. But another reason is the high clearance of the bridge.

We can see the road bridge in the background of this photo of the PAL/IC Bridge. It also shows the high clearance of the road bridge. Note that the railroad bridge has a rather large clearance, but it still has a movable span.

Thanks to Tim Williams for sharing the picture of the Rockport Railway Bridge.

This documents the incredibly high clearance of the bridge. Steamboats were obsolete by the 1930s. I think 60' is the accepted clearance for barge traffic. So I don't know why this bridge is so high and has such steep approach grades.

Peabody did transport some big draglines on the Green River. But it started mining in this area in the 1950s, well after the bridges were built.

Kudos to KY DOT for maintaining the truss.

1894-2012 OOS/CSX/C&O Bridge over Gauley River at Belva, WV

Bridges & Tunnels by Sherman Cahal posted two photos with the comment:

The Belva Railroad Bridge carried the Chesapeake & Ohio Railroad (C&O) Greendale (Gauley) Branch between Gauley over the Gauley River in Belva, West Virginia. Constructed c. 1893-94, the 1,126-foot [343m] bridge was last used c. 2012 when the last coal mine on the branch was idled.

Stan Carlson commented on the above reel
Here is the construction of the arch. This was an overpass the BR&P built over the Kushequa RR. The actual location was originally called Newton, later named Backus. My Great Grandfather, and Grandfather were section gang foremen here with 70 years of service between them.

Stan Carlson commented on the above reel
My Grandfather’s and Great Grandfather’s gangs teamed up to raise the track on either side of the arch in August 1927. Great grandpa has the shovel wearing his Stetson Derby, and grandpa is holding the level. My great uncle is standing by the generator with an oil can. This and a couple of other photos were taken for the BR&P Ry employees magazine “Railway Life”. Only one photo made the October 1927 magazine.

Tom Huntoon commented on the above reel
This was the Kushequa Railroad. It went down the valley and under the Kinzua Bridge.

Before I saw the comments about the bridge being for a railroad rather than a creek, I wondered why the water of the Little Black Brook was so far from the bridge.

I don't normally note railroad overpasses, but the comments on this post provide a lot of information about the B&O branch

Need  some  help...

I’m  doing  research  on  a  CSX  single  span  through  truss  bridge  west  of  Indianapolis  that  spans  the  former  B & O  Rail  line:  GPS  Coordinates:  39°47'40.4"N 86°18'18.7"W.  Does  anyone  know  when  that  section  of  the  B & O was  closed  and  does  anyone  know  where  I  can  find  pictures/video  of  trains  on  that  section  of  B & O rail  line  or  of  trains  crossing  the  CSX  bridge  above?

AJ Clapp: Here is video from I believe the section foreman taken from the caboose of one of the last revenue trains. West out of Indy to I think somewhere west of Marshall, In

Delaware Dam on the Olentangy River.
Doug Chapman shared with the comment: "Delaware Dam near Delaware Ohio on the Olentangy River. Built 1951."

"The dam is 3.5 miles [5.6km] long and 92 feet [28m] high, and controls a drainage area of 386 square miles through the use of five gated sluices and six 25-foot by 32-foot tainter[Parker]/radial gates."

I was surprised by the length of the dam, so I took a closer look at a satellite image. The part that went east of the spillway to Horseshoe Road was obvious. Then I noticed that the western part goes North along US-23 and then turns west up by Wiley Road

In fact, US-23 appears to be an emergency spillway.

Street View, Aug 2025

There are campgrounds in the floodplain. So I hope they do a good job of getting the campers evacuated before the grounds become flooded.

Satellite

The spillway capacity is 96kcfs. [delaware-county]

A satellite image caught the dam with three of its sluice gates open.

Three gates is the max flow I saw looking at Google Earth images. When the flow is smaller, we can see the wall for the stilling basin.

It looks like the reservoir was holding flood waters in Spring 2019.

Nisutlin Bay Bridge in Yukon, CA, can't use new bridge because of abutment problems

15:35 video
Nisutlin Bay Bridge Mess
In this video, I discuss what are the likely geotechnical issues for a major bridge project in Canada that has resulted in the termination of the contracts with the bridge contractor and the bridge designer resulting in a current work stoppage for a the Nisutlin Bay Bridge in Teslin, Yukon Territory Canada.
"This bridge is the largest  construction project ever in the history of the Yukon." [0:10]
The old bridge was completed in 1956.

The bridge abutments use a relatively new design that was developed for Accelerated Bridge Design (ABC). The abutment consists of a standard pier and a Mechanically Stabilized Earth (MSE) retaining wall joined by a jump slab.

@ 9:10

I think the problem is that the MSE is subjected to landslide forces that it cannot handle.

@ 10:56

I could not find a photo in their construction photos that shows the stringers to see if they are steel or concrete girders. This photo shows the temporary trestle that was used to build the new bridge. Of course, this official site talks about environment protection but does not about abutment booboos.

This photo implies steel girders. In fact, they are made from weathering steel.

yukon_fun_facts

Their Facebook page does admit there is a problem, but that is all. The page ends with a Jun 4, 2025, post saying: whoops, we have geotechnical problems and we are investigating.

I did find a more recent FAQ. I've seen reference to money spent in Nov 2025 for remedial work on the old bridge. So, they must assume it is going to take a while to fix the abutments. Originally, the new bridge was supposed to open Spring 2026. It looks like it would have been on schedule if the abutments did not have a problem.

Since they discovered the problem in Jun 2025, they have been studying the problem for a year, but they still don't have a fix. That doesn't bode well.
