I've screwed up and there are quite a few construction photos in
Kentucky Dam.
This PDF file describes the construction of the new lock.
The
Kentucky Dam currently has a 110x600 foot lock. It is a bottleneck because 15-barge tows have to be split in half to go through a 600' lock. In fact, a Bing satellite image caught the upstream gates closing after the front part of a tow had been winched out of the lock. And you can see the rear part of the tow below the downstream gates waiting for its turn. You can also see that they have built the cofferdam and have begun excavation for the new 110x1200 foot lock.
A Google satellite image is more recent, and it shows that some of the walls of the new lock have been built. I believe there is just one barge in the lock in this image and that it hauls a liquid product. I have noticed before that liquid barges tend to be bigger than a normal materials barge.

The current lock is busy enough that we caught these two tows heading upstream as we drove over the dam to the Visitor Center. We were taking a picture of the
railroad bridge truss and probably did not notice the tows until later. Below is a photo I had already taken of three 1200' tows parked upstream. (There are two tows parked side by side on the right.)

Looking further upstream on the Google satellite image, I see there are four tows parked waiting for that liquid-products barge to finish locking through. There are also four coal barges tied up closer to the shore.
Later, after I had parked in the Visitors Center parking lot and was walking around is when I noticed the two tows heading upstream. You can look at the 3:17 photo above and compare to this 3:22 photo to see how far the tows have moved in five minutes.

As we left the dam, my wife took quite a few pictures from the US-62/641 bridge you see at the top of the above picture. I include the two yellow tower cranes that are helping to build the new lock. You can tell it is the same tow we saw in the previous pictures because of the two white barges in front. So 14 minutes later it is about to enter the lock. It took longer to cover the distance between the second and third photos than between the first and second photos because they slow down to less than a walk when they get close to the lock walls. The "blue bar" of the bridge's guard rail blocks seeing the joint between the second and third row of barges. It is obvious the tow has 15 barges, and it will have to be locked through in two segments.

posted two photos with the comment:
Riverview Boat Store & Tug Service's M/V JEAN MARIE seen here locking up at Kentucky Lock with a deck barge. This is at Mile 22.4 on the Tennessee River.
This lock serves as the lower gateway to over 700 miles of navigable waters on the Tennessee River from Paducah, Kentucky to Knoxville, Tennessee.
The lock was completed in 1942 by The Tennessee Valley Authority with the Kentucky Dam creating a 184 mile reservoir pool.

Kentucky Lock
posted eight photos with the comment:
Local Photojournalist Robert Offenback shared a few of his pics from the movement and placement of the 1.3 million pound concrete shell on the downstream side of Kentucky Lock. The shell is the first of 10 that will make up the new lock wall and will be used as part of the coffer dam during construction of the new lock. Thanks Robert for sharing your photos with us.
What if tows hits this while locking upstream thru the lock ?
We have a helper boat in place to help them by it. It will be filled with concrete over the next couple weeks, then it will be solid and good to go.

Barkley Lock can be used as a detour by using the

Kentucky Lock
posted nine photos with the comment:
There are 6 tower cranes, 2 crawler cranes and 2 wheeled cranes doing the heavy lifting (literally) at the Kentucky Lock construction project. The tower cranes all have a 262.5-foot boom and can lift between 22 and 27 tons each.
Cranes are essential to the project as they are the hands that assemble the formwork, reinforcing bar, concrete and materials to safely construct the lock monoliths and gate structures.
3 of the tower cranes use a 270-foot long conveyer system with an "elbow" near the middle to support placement of the concrete in the elevated areas of the project saving time and money. These cranes span an area greater than 1,600-feet.
