A grey bridge against a grey sky is a bummer, but I can't change the weather. Fortunately, cranking up the contrast did help some.
|I drove down a side street trying to get a closer view.|
|But the closer I got, the more the obstructions got in the way.|
Over the river, they reused the old bridges piers, but in the approach they changed to a steel trestle. However, they let the old truss piers stand. Illinois Central Railroad Scrapbook The approach trestle on the Kentucky shore is not original. By the early 1930s the trestle was falling apart due to a combination of heavy use and brine dripping from reefers. So, the original trestle was replaced by an all new approach trestle. Incidentally, believe it or nor, there also was a steel approach trestle on the north side of the bridge. Around 1903-1905 it was replaced by the massive fill and freight yard that still exists.

"LOOK OUT BELOW!!"
Between 1950 and 1952 the IC rebuilt its Ohio River bridge at Cairo, IL. To save costs the existing piers were reused, and new spans were constructed on a floating platform next to the bridge. Once the new span was ready, the old span was pushed out of the way and the new span was rolled into position. This technique had never been attempted before on bridges of this size.
After each span was replaced, it was stripped of rails, ties, wires, etc. The steel skeleton was then dropped into the Ohio River, accompanied by a massive SPLASH, and divers would then cut up the span for scrap. In this view from August 21, 1951, the third span is taking the dive. This view is looking from the Illinois shore towards Kentucky. Collection of Cliff Downey
Alex Sansone How exactly was it pushed over ?
Illinois Central Railroad Scrapbook When each span was replaced, it was rolled onto a steel platform next to the pier (the platform is visible in the photo above). At the top of the platform is a "sled" that attached to the bridge span, and the sled was on an incline. The pins holding the sled were pulled, a barge would give a gentle tug, and then gravity did the rest.
Lou Maxberry I was present at one of the replacement sections. As info. The contractor that removed the steel from the river was blind also all of his divers were blind.
Mike Thompson Just layer rail over that a few years ago
Cliff Downey posted two photos with the comment:
In recent weeks I've posted several photos of IC's Ohio River bridge at Cairo, IL, taken in the early 1950's when the bridge was rebuilt. Here are a couple more, but a little background info is needed to understand these photos.
On November 14, 1951, crews from American Bridge Company (the contractor on the bridge project) replaced the 400' through truss span on the far southern end of the bridge with a pair of 200' deck girder spans.
During the move the old span was moved onto a platform next to the bridge and afterwards was stripped down to a bare frame. Once stripped, the old span would be dropped to the ground so it could be cut up for scrap and hauled away.
By the afternoon of November 28 all was ready for the span to make its great fall. In one of the photos, the old span can be seen resting on the temporary platform. Note that the span is sitting atop a skid, which itself is mounted on an angled ramp. Once the all-clear is given, a few bolts and pins under the ramp were removed, and a winch mounted on a barge gave a good tug.
Gravity then took over and the span fell onto the river bank below. As seen in the second photo, on the day the span fell, the river bank was partially flooded. Note that at the end of each of the old spans was a beam with the words "Cairo Bridge" cast into it, along with 1889, the year the bridge was completed.
