Walsh Construction has placed the first sections of bridge deck panels for the Downtown Span of the Ohio River Bridges Project in Louisville, Kentucky.

The First Structural Steel Girders For The Downtown Span are Installed

This post and the accompanying photos show how much progress has been made on the Downtown Span of the Ohio River Bridges Project in Louisville Kentucky.

I decided to try some black and white images of Ironworkers today. The image above is from The Ohio River Bridges Project.  Nothing fancy just used Aperture 3 for conversion to black and white of a HDR image that I had done in the past.

Jack Alpha is an Ironworker with T&C Construction who was working on top of the Big Four Bridge when I shot this image. I converted it to black and white in Aperture 3 using a single frame. This isn’t HDR but I still think it is full of detail.

Work On Southbound I-65 Bridges and Roadway Progresses

The southbound I-65 work is progressing well as the Walsh Construction crews build the new bridges and roadway that will replace the old I-65 infrastructure. In this photo you can see the steel bridge decking being installed in the center of the image while an Ironworker welds the supporting angle iron in place. I chose this image because I like the way the figures are arranged from the foreground through the frame. I also like the way the welding arc is sparking and the way the welder is positioned in the image.

As in most of my work this too is a HDR image created from a three frame bracket set of +2, 0 and -2 EV exposures. I had to use an anti-ghosting setting of 100% in NIK HDR Efex Pro 2 to address the many different poses the figures were in between frames. The ability to shoot handheld images of people movin

This second image also shows the Ironworkers welding and placing the steel bridge decking. The decking will support the concrete during the pouring of the roadway after the Ironworkers place reinforcing rebar across the completed bridge deck prior to pouring of the concrete. Once again you can see the power of the NIK HDR Efex Pro 2 anti-ghosting feature, especially in the way it has rendered the woman’s leg as she kicks the steel decking into place. As in the previous image I had to use a setting of 100% anti-ghosting in order to freeze the action and avoid ghosting artifacts.

I really liked the way the pre-stressed concrete bridge beams cast their shadows on the ground below them and the strong movement their placement gave to this image. This is also near Slugger Field where the new roadway is taking shape overhead. Once these bridges and roadways are completed traffic will be moved over onto this new roadway and demolition will begin on the old southbound I-65 infrastructure which will be replaced with new bridges and roadway. Once again I followed my normal HDR workflow of NIK HDR Efex Pro 2 and Aperture 3 processing.

This final image in today’s post is once again from beneath the concrete bridge beams for the new southbound I-65. I shot this using my 12-24 mm Nikkor lens and decided to take it into Photoshop CS5 after merging the bracket set in order to correct the lens distortion inherent in such a wide angle shot. This too is a HDR image created from a three handheld frame bracket set merged in NIK HDR Efex Pro 2 and finished in Aperture 3.

Going Up

The Ironworkers and Carpenters have been very busy over the winter and the North Tower of the Downtown Span is progressing well. In this first image you can see the tower base as it stands today. The Ironworkers are tying the rebar for the next section and as soon as that is done the Carpenters will form that section for the next concrete pour.

I regret that I was under the weather for the first two months of this year and unable to get out to the Ohio River Bridges project very often. In looking back at the images from the end of 2013 I can see that there has been a great deal of progress. I’m back on the job now and will be posting on a regular basis as I did throughout the end of summer and into fall.

All of these images today are HDR images processed in NIK HDR Efex Pro 2 and Aperture 3. As is my standard practice I shot everything handheld in three frame bracket sets of +2, 0 and -2 EV exposures. I applied 60% anti-ghosting during the merging of these three exposures and used the Balanced Preset as my starting point. After merging them and applying the preset I went back into the tone mapping settings and changed the Detail slider to Accentuated and the Drama slider to Deep. That is all I did in NIK HDR Efex Pro 2 before returning the merged file to Aperture 3 where I adjusted the color channels, sharpening, contrast and applied a small vignette.

In this image the Ironworkers are working with the crane Operator to lift more materials onto the tower scaffolding. They have to communicate with the Crane Operator using hand signals and radios to safely manage material transfers. I am always amazed at the skill of these crane operators to place everything from a small bundle of steel reinforcing to massive concrete forms on the job with pinpoint accuracy.

In this HDR image the concrete form is being removed from the angled surface of the eastern side of the eastern pier of the North Tower. The carpenters have unbolted it and rigged it for the crane Operator to lift it and transfer it to a waiting barge until it is needed again. Seeing the Carpenters alongside these forms gives scale to their size. Once again the Crane Operator and the Carpenters are working through radio and hand signals to safely move this massive piece of concrete form.

For this HDR image I chose to shoot the removal of the concrete form in a vertical format to better capture the cranes and the upward momentum that the project exudes as it progresses.

This HDR image shows both bases for the North Towers of the Ohio River Bridges Project Downtown Span. The progress that is being made really comes out in this HDR photo. The concrete forms have been removed from the base of the western side of the towers and scaffolding is surrounding the transition point as the base morphs into it final cylindrical shape which will be approximately 150 feet in the air when it is completed.

This HDR image shows a cooling manifold being lifted into place. It is used to distribute cooling water through the concrete as it cures. When concrete cures there is a lot of heat inside it; this is due to the catalytic reaction of the materials that are used to make concrete. Without cooling this reaction would cause the concrete to overheat and lose it’s strength. The cooling process goes on until sensors built into the structure provide the information to show that it is safe to stop cooling the concrete and allow it to finish curing.

I’m really glad to get back to shooting the Ohio River Bridges Project and posting my work again. I hope that small hiccup at the beginning of the year won’t be repeated and I can complete my project of documenting the Ohio River Bridges Project and the men and women who are doing it.
